▼ This thesis presents a cost-benefit analysis of
tidal
power generation with specific reference to the installation of a
300MW
tidal farm in the Minas Passage, in Nova Scotia, in 2020, as
a case study. Nova Scotia has set aggressive targets to increase
the share of renewables in the province’s electricity generation
mix and
tidal energy is considered to be the ?sleeping giant?
amongst renewable energy sources. After having estimated the many
costs and benefits and having calculated the net present value of
such a project, it is concluded here that the project should not
proceed as its costs greatly surpass its benefits. However, it is
recommended that further studies evaluating the costs and benefits
at different levels of
tidal penetration be conducted for the
province.

▼ ABSTRACT:
Tidal networks are characterized by an intricate hierarchy of channels and shoals, acting as one of the most striking morphological features in coastal and estuarine environments. Located at the land-sea boundaries, they are shaped by feedbacks between a variety of processes operating over a wide range of temporal and spatial scales. The aim of this thesis is to investigate the effects of the major processes and their associated feedbacks on the long-term morphodynamics of
tidal networks.
Through a comparative study of physical and numerical modeling of
tidal networks, this research indicates that fast- and small-scale models can reproduce the long-term morphological evolution of
tidal networks. Quantitative comparisons in terms of a variety of different geometric measures are conducted and suggest that numerical modeling is a useful tool to unravel the mechanisms underlying the morphodynamic behaviors of
tidal networks. This research also constructs a comprehensive framework to study the river-influenced
tidal network system and explores the physics governing the distribution of different types of sediment on intertidal flats.

▼ Io is Jupiter's innermost Galilean satellite and the most volcanically active body in the Solar System. Its volcanism is driven by tidal heating generated by its interaction with Jupiter and maintained by other Galilean satellites. The tidal forces acting on Io also cause significant stresses on its interior. It is investigated if tensional stresses play a significant role in the formation of volcanic centers on Io. On a global scale, it is investigated if the locations of maximum tensile stress coincide with the locations of maximum volcanic activity. On a local scale, it is investigated if chains of Io's volcanoes follow the directions of the tensile stresses. The results on a global and local scale are shown to be consistent with the hypothesis that tensional stresses play a significant role in the formation of volcanic centers on Io. However, tensional stresses alone are insufficient for the formation of volcanic centers.

▼ This thesis discusses the importance of tidal turbine support structures through analytical and computational modelling. A head-driven analytical channel model was first developed to determine the sensitivity of the flow to the presence and type of support structures. It showed that there was a significant potential reduction in farm power output even when only considering approximate force coefficients for rotor and support structure. To confirm these findings, computational simulations were performed on a full-scale turbine to obtain more accurate force coefficients considering full rotor-support structure interactions. The flow interaction effects between the rotor and its support structure were studied using Computational Fluid Dynamics (CFD) for different support structure shapes for a range of tidal velocities including the power-capping zone. The integrated rotor force coefficients were higher in the presence of the cylindrical support structure than the elliptical support due to the higher opposing thrust from the cylinder in the channel redirecting the flow and increasing the flow velocity over the top half of the rotor. The presence of rotor caused a drop in the stream-wise forces on the support structure. The amplitude of the stream-wise sectional forces along the support structure height was lower in the case of an elliptical than a circular cylinder due to more streamlined shape of the ellipse. At device scale, the computational model was used to study the turbine performance in the power-capping zone by pitching the blades to feather. The influence of pitch-to- feather power-capping strategy was examined by studying the forces and angle of attack on the turbine blades, and the wake at three different blade pitch angles. Increasing blade pitch angle resulted in a significant drop in the average load on the blade. Also since the tidal channel flow has a shear in its velocity profile, the influence of shear on turbine performance was studied by comparing it to the same turbine in a uniform flow. The analytical channel flow model was used to investigate the characteristics of tidal stream energy extraction for large tidal farms deployed in tidal channels with specific focus on the limitations to realizable farm power due to turbine support structure drag and constraints on volume flow rate reduction. The force coefficients dataset from computational modelling was used to obtain a better estimate of the farm power output. Support structures were seen to contribute significantly to the overall resistive force in the channel and thus reduce the overall flow rates in the channel, leading to losses in realizable power. Over a wide range of channel characteristics, realistic levels of support structure drag lead to up to a 10% reduction in realizable power, and an associated reduction in the number of turbines that can be economically installed.

▼ This thesis investigates sublittoral epibenthic assemblages, the ecological processes associated with distributions of benthic assemblages and potential ecological impacts arising from the de-ployment of tidal energy devices (TEDs) at a key tidal energy development site. An extensive field campaign was undertaken to collect fine-scale, in-situ data for local hydrodynamics, seabed structure and epibenthic assemblages. Data from a two-dimensional hydrodynamic model com- plemented in-situ flow data and provided an insight into possible changes to local tidal patterns after the deployment of a tidal array. The study revealed a highly complex tidal stream structure with maximal velocities reaching 4.2 ms1 during spring tide. The seabed was predominantly formed by scoured bedrock. Deployment of a tidal array was predicted to decrease tidal flow within and downstream of the array by up to 24 % for peak flows, whereas effects on the seabed were thought to be minor. Epibenthic assemblages were typical for tide-swept channels with a fringe of dense kelp forest along the shallow, sheltered waters of the channel, followed by a 'tran- sition zone' dominated by foliose red algae in the mid-depth ranges and animal turf assemblages in the deeper, very tide-swept waters. Multivariate analyses identified depth and bed-shear stress as being strongly associated with the distribution and composition of assemblages. In conjunction with presence-only data for epibenthic species, depth and bed-shear stress were used as predic- tor variables to develop site-specific habitat suitability models (HSMs) for a baseline and TED deployment case. Comparison of probability of occurrence values between the respective HSMs indicated a potential increase of suitable habitat for species inhabiting the deep, very tide-swept circalittoral following the deployment of TEDs, whilst assemblages along the fringes of the channel were mostly unaffected. This is the first attempt of using HSM as a tool for identification of potential changes in distributions of benthic species arising from the deployment of TEDs. The good overall performance of the models shows this tool may be valuable for for impact analysis of tidal energy development projects.

▼ The long term evolution of the relative rotation of the core super fluid in a neutron
stare with respect to the rest of the star is determined through Legase modal.The core
superfluid rotates at a different rate ,while spinning down at the same steady-state rate as
the rest of the star, because of the assumed pinning between the superfluid vortices and
the superconductor fluxoids.We find that the magnitude of this rotational lag changes with
time and also depends on the distance from the rotation axis; the core superfluid supports
an evolving pattern of differential rotation. We argue that the predicted change of the lag
might occur as discrete events which could result in a sudden rise of the spin frequency of
the crust of a neutron star, as is observed at glitches in radio pulsars. This new possibility
for the triggering cause of glitches in radio pulsars is further supported by an estimate
of the total predicted excess angular momentum reservoir of the core superfluid. The
model seems also to offer resolutions for some other aspects of the observational data on
glitches. The goal of this project is to show the
tidal effect on the differential motion of
the crust with respect to the core of the neutron star from that we find the redistribution
of angular velocity and
tidal locking time for the crust core interaction of neutron stare.

▼ In this thesis the position of
tidal divides is studied by means of a simplified model and the Dutch Wadden Sea. To study the parameters influencing the location of the
tidal divide, two basins are schematized to a rectangular channel with at each side an incoming
tidal wave. These two incoming waves can differ in amplitude and have phase difference. The
tidal divide is shifted towards the channel end with the largest wave amplitude or the end where the wave enters last. If the phase difference and/or wave amplitude ratio between the two incoming waves is too large, there is no
tidal divide at all. It turned out that a distinction between two cases can be made: a linear case with very low wave amplitudes and flow velocities, in which the bottom friction is neglected; and a nonlinear case with higher wave amplitudes and velocities resulting in a dominant role of the bottom friction. The limit of the phase difference for the Wadden Sea means that the barrier islands should have a certain length and/or that the basin should be relatively shallow. In the linear case, the difference in amplitude between the two waves is most important in determining the location of the
tidal divide. The contribution of the phase difference is minimal. When bottom friction becomes dominant, the phase difference is governing the position of the
tidal divide and the influence of the amplitude ratio is very small. The depth of the channel is an important parameter, because it influences the importance of the bottom friction. In the Wadden Sea, both the phase difference and the difference in
tidal range in the inlets is contributing to an eastward location of the
tidal divides. In this thesis, a distinction is made between a hydraulic
tidal divide and a morphological
tidal divide. A hydraulic
tidal divide is the line splitting the basins in terms of drainage and can be defined as the position where the standard deviation has a minimum. Engineers are looking for a clear line, because then the hydraulic
tidal divide can be used as a basin boundary. In reality there is no line, which makes it difficult and arbitrarily to define a line. This has to be kept in mind when analyzing hydraulic
tidal divides. In the Wadden Sea, the morphological
tidal divide has the shape of a spine. The centre line of this spine does not necessarily coincide with the highest bed level. The morphological
tidal divide is the footprint of the hydraulic
tidal divide on the bed and indicates where the hydraulic
tidal divide is or has been. The height of the morphological
tidal divide can tell something about the equilibrium of the basins. The hydraulic and morphological
tidal divide can move due to changing circumstances, like closure of a part of the basin. The hydraulic
tidal divide can move instantaneously, but its shift is bounded by the morphological
tidal divide. The morphological
tidal divide first has to be lowered by increased flow velocities and then the hydraulic
tidal divide can move more freely. The morphological
tidal divide then heightens again at the new…

tidal flats, and floodplains.
A total of 28 trace fossil forms were identified in the upper Sego and Neslen fms including 14 fully marine traces, 11 facies breaking traces, (those traces that can exist in fresh, brackish, or marine salinities), 1 freshwater trace, and 2 continental traces. Ichnology was critical for refining paleoenvironmental interpretations and was used to distinguish between deposits of distal
tidal-fluvial channels and proximal
tidal-fluvial channels, and
tidal flats and floodplains. The Teredolites ichnofacies was used as an indicator of marine flooding events.
Neslen sandbodies preserve inclined heterolithic stratification in point bars of estuarine
tidal-fluvial channels. In contrast to recent studies, bayhead deltas and deltaic deposits were not identified in the Neslen near Harley Dome. Carbonates that include stromatolites and oolites are identified for the first time in the Neslen. The predominance of distal to proximal
tidal-fluvial channels and
tidal flats, abundant marine ichnology, the recurrence of the Teredolites ichnofacies and carbonates, and the lack of bayhead delta or wave-modified deposits suggests deposition within a distal, yet protected estuarine environment.
The Neslen Fm near Harley Dome provides an analogue for a heterolithic, paralic reservoir system. Due to the heterogeneity that is evident at multiple scales within tidally influenced systems, the outcrops of the Neslen Fm in the Harley Dome, UT area provide an analogue to examine the distribution of various heterogeneities and facies in estuarine deposits that could ultimately affect reservoir performance.

▼ This research describes the position, strength and variability of the mixing front along the East Shetland coast and the geostrophic current associated with the front. Between 2004 and 2010, new current meter measurements have been made at two mooring sites on the East Shetland shelf. By combining the current meter datasets with other surface temperature and salinity observations, such as surface underway data from the ferry MV “Norröna” and existing hydrographic datasets, this research provides new insights into the seasonal variability of the currents on the east Shetland shelf. The results show that in this region of the northern North Sea the balance of heating-stirring results in a tidal mixing front close to a (log10( h/u3)) of 3.4. Along the steeply sloping shelf to the east of Shetland a mixing front is found in water around 100m depth and results in significant geostrophic currents of up to 20 cm/sec between June and August each year. Monthly volume transports associated with broad scale wind forcing are estimated to be between -0.27 and -0.51 Sv during the well mixed periods (December to March). During the summer months (June, July and August) wind driven transport reduced to an average of -0.27 Sv, at the same time the persistent southerly flow associated with the geostrophic transport contributes an equivalent transport (-0.24 Sv). Taking the east Shetland shelf as a whole (coast to 1.5°E) the maximum volume transport is estimated to occur in Autumn (September to October) when density driven currents remain significant and wind speeds begin to increase. In the narrow region close to the coast, however, monthly mean volume transport is observed to be highest during the summer months as a result of the strong jet-like currents that flow along the density front.

▼ The design of complex technological systems required an early outlook of institutional issues. The paper suggests a design methodology to combine institutional design and engineering design. The design methodology is applied to a case study of tidal power development in the Klabat bay, Indonesia. In the case study it is shown that there are interactions between institutional design and technological design. Ignoring the institutional environment the financial and economic performance of tidal power in the Klabat bay is poor for all options. Incorporation of institutional design allowed for creative thinking that could allow for the decision to continue feasibility research. The inclusion of institutional design therefore proved valuable. The design process did become more complex.

▼ The fairway connecting Holwerd and Nes forms the main transport route between Friesland and Ameland (the Dutch Wadden Sea). It consists of several
tidal channels that funnel the majority of the
tidal currents propagating through the
tidal basin. Over the past decades, several channel bends have expanded leading to a fairway length-increase of about 1 km, and the channel in front of Holwerd has become
subject to sedimentation. Since 1990 this channel was dredged and the volume of dredged material has increased exponentially. A relation between dredging activities, channel migration and frequent delays of the ferry has been suggested. The main goal of this thesis is therefore to explain the difference in evolution between the non-natural (intervened) and natural
tidal meanders in the Ameland basin. To achieve this goal, the evolution of geographic channel dimensions are analyzed by assessing bathymetric data and the outcome is linked to the physics by means of hydrodynamic modeling. Channels have been classified based on their locations and dimensions. Three meandering stages have been identified that describe the basic channel behavior. The first meandering stage is the developed meander, characterized by a clear sinusoidal shape and with flood chutes. In this stage, the depth at a cross-over is approximately two times smaller than at the channel section with a maximum curvature (the channel top), where the width profile is funnel shaped. The developed, variable meander has similar characteristics, but differs by a lower correlation in width and depth, and closer to the
tidal watershed the ebb channel location varies more in time. The third stage is the undeveloped meander, which is characterized by small and relatively straight channels, the absence of flood chutes, and a rather constant width- and depth-profile along the channel. In this study, the channels are evaluated that have similar meandering features and distance from the Ameland inlet as the dredged channels. In general, the examined channels showed a width reduction that dominates over the bed level decrease. An irregularity in the width and/or depth profile is an indicator for the development of a bifurcation or flood chute. Numerical modeling of the
tidal currents revealed a correlation between the depth averaged velocity and the funnel shaped channel top. From the depth averaged velocities it is found that flow accelerates around the channel tops, where flood dominance prevails and flood chutes (are able to) develop. During ebb, a similar acceleration occurs towards the point of inflection, where ebb dominance prevails. Increasing meanders correspond to a shift towards ebb dominance in both natural and non-natural channels. By evaluating the secondary flow velocities along the channels, an eastward shift of the cross-over location is observed. Whether the shift corresponds to the channel migration, or that it strengthens the potential for channel splitting is not proven. However, an indication is found that a correlation exists between the distance…

▼ In river and tidal stream power assessment, uncertainties arise from model assumptions and the inexact specification of physical and numerical model parameters. Combined, such uncertainties can greatly affect power estimates for a given site. The thesis examines the effects of bed roughness and turbine drag uncertainties on turbine power estimates. An analytic model is developed for transfer of bed friction uncertainty to power extracted from turbines in a strait, representative of a river. A validated finite volume solver of the shallow water equations is developed and applied to simulate flow driven by a constant head difference through a one-dimensional strait. The presence of a turbine fence is included using enhanced bed friction. A parameter study examines the effect of uncertainty propagation from bed friction to power. Excellent agreement is obtained between the analytic and numerical power uncertainty estimates for a given input bed friction PDF. Perturbation methods are used to determine the leading-order effect of bottom friction uncertainty in tidal stream power assessment. The theoretical models consider quasi-steady flow in a channel completely spanned by tidal turbines, a similar channel but retaining the inertial term, and a circular turbine farm in laterally unconfined flow. It is found that changes to expected power depend on the dynamic balance in the channel, the turbine configuration, and the geometry of the site considered. Bottom friction uncertainty increases estimates of expected power in a fully-spanned channel, but has the reverse effect in laterally unconfined farms. The optimal number of turbines under bottom friction uncertainty is lower for a fully-spanned channel and higher in laterally unconfined farms. The effect of uncertainty in turbine drag is also considered. A standard methodology is presented for uncertainty propagation using general computational models. The methodology is tested using a shallow flow model of the Pentland Firth, where power statistics are determined according to input bed friction probability distribution, and the results compared against those from the (simplified) analytic perturbation approaches. Although the analytic models for channels perform reasonably well regarding the estimate of expected power, the predictions from the unconfined analytic model were not so satisfactory owing to the model assumptions. The methods for uncertainty transfer presented in the thesis could readily be applied to many other problems encountered in hydraulic engineering, such as river flow routing, urban flood risk, reservoir sedimentation, etc.

▼ Computer technology is growing fast in recent years. Modeling technique is used in predicting or in planning engineering works and even in preventing disaster. Modeling is widely used in many domains and unmanned Real-time online operation modeling systems on prediction become popular. Model may become inaccurate due to a number of uncertainties in the approximation and by numerical reasons. Data Assimilation technique is developed to solve this problem. Measured data is used to improve the model results. In this research, the Cressman scheme was chosen as the data assimilation scheme and used for correcting the modeling system.
An idealized model was constructed first as Taiwan Strait. In order to test the stability if data assimilation system several geographical variations and data availability cases were designed, eg adding varying bottom topography, an island added in the domain, different measurement data locations. In order to test the model sensibilities an error was inserted to the boundaries. Model results were first corrected with data assimilation system for a period of time, a Harmonic Analysis was, then, used for reanalysis the corrected time series on the boundaries. The new boundary condition is used in the new model run for making predictions. A true topography and island system as Taiwan Strait was tested with the true astronomical tide as the boundary input.
The data assimilation system using the Cressman scheme could reduce the RMSE effectively. The factor that affects the efficiency of the data assimilation system is the number and the location of the measurement data.

▼ Ever since Van Veen (1950) described the different
tidal channels in the Western Scheld, people
have known of their existence. Ebb and flood use different
tidal channels in an estuary, and form
certain patterns to lead these different tides through. The exact process that forms these ebb-flood
tidal channel pairs remains a mystery however. Previously it was not possible for scientists to
investigate this formation with something different than modelling, but with the introduction of the
‘tilting flume’ it has become possible to imitate
tidal behaviour on an experimental scale. This study
has been done to try to find the factors determining the formation of
tidal channels and whether
they form an equilibrium or not.

▼ Current technology and theoretical methods are allowing for the detection of sub-Earth sized extrasolar planets. In addition, the detection of massive moons orbiting extrasolar planets (“exomoons”) has become feasible and searches are currently underway. Severalextrasolar planets have now been discovered in the habitable zone (HZ) of their parent star.This naturally leads to questions about the habitability of moons around planets in the HZ.Red dwarf stars present interesting targets for habitable planet detection. Compared to the Sun, red dwarfs are smaller, fainter, lower mass, and much more numerous. Due to their low luminosities, the HZ is much closer to the star than for Sun-like stars. For a planet-moon binary in the HZ, the close proximity of the star presents dynamical restrictions on the stability of the moon, forcing it to orbit close to the planet to remain gravitationally bound. Under these conditions the effects of tidal heating, distortion torques, and stellarperturbations become important considerations to the habitability of an exomoon.Utilizing an evolution model that considers both dynamical and tidal interactions, I performed a computational investigation into long-term evolution of exomoon systems. My study focused on satellite systems in the HZ of red dwarf stars and the dependence of exomoon habitability on the mass of the central star. Results show that dwarf stars withmasses < 0.2 M© cannot host habitable exomoons within the stellar HZ due to extreme tidal heating in the moon. These results suggest that a host planet could be located outside the stellar HZ to where higher tidal heating rates could act to promote habitability foran otherwise uninhabitable moon. Perturbations from a central star may continue to have deleterious effects in the HZ up to « 0.5 MSun, depending on the host planet’s mass and its location in the HZ. In cases with lower intensity tidal heating, stellar perturbations mayhave a positive influence on exomoon habitability by promoting long-term heating rates above a minimum for habitable terrestrial environments. In addition to heating concerns, torques due to tidal and spin distortion can lead to the relatively rapid inward spiraling of a moon. The effects of torque and stability constraints also make it unlikely that long-term resonances between two massive moons will develop in the HZs around red dwarf stars.My study showed that moons in the circumstellar HZ are not necessarily habitable by definition. In addition, the HZ for an exomoon may extend beyond the HZ for anexoplanet. Therefore, an extended model is required when considering exomoon habitability in comparison to exoplanet habitability.

▼ Understanding the circulation of the oceanic currents provides information to mitigate the impact of hazards and to respond timely in the case of an emergency by making critical decisions promptly. In early 2016, the Geochemical and Environmental Research Group (GERG) started the installation of a High-Frequency (HF) radar network in Texas to improve the spatial resolution of the in situ oceanic measurements presently collected by the Texas Automated Buoy System (TABS). Both systems, HF radar and TABS, are operated and maintained by GERG. The present research thesis analyzes 2 out of the 3 HF radar sites (Rollover and Surfside), and 4 out of the 9 TABS buoys (B, F, W, and R), for a period of ~17.5 months, from June of 2016-November of 2017. During this analysis the summer reversal for 2016 and 2017 is captured, noting that it occurred in mid-June – mid-August, and a few days earlier in 2016. Based on correlation coefficients, SSDE performs better than RLVR, particularly when compared to buoy F. Bathymetry and salinity impact the performance of the HF radar, and there is potential attenuation on RLVR by ship navigation. Variance ellipses tend to follow the 50-m isobath, in agreement to Nowlin et al. (2005) inshore-offshore isobath limit definition, with a dominant NE-SW orientation of the major axis, with a higher variance associated with regions of less data density and steeper gradients in the bathymetry. Power spectra showed an increase in the energy in the diurnal and semidiurnal frequency, with a predominant clockwise rotation as indicated by rotary spectra. Coherence analysis showed coherence >95% confidence interval near the inertial band is indicative of rotation due to inertial response. The main
tidal constituents found in this thesis are O1, P1, K1, M2, and S2. Wavelet analysis also showed an increase in the diurnal and semidiurnal period, as well as an increase in the energy in the weather band (2-15 days), and high power content on the diurnal band during the summer for the detided record, suggesting that this is due to sea-breeze effects and inertial motions, given that the local inertial period is 24.78 hrs.

▼ A one-dimensional, implicit, finite-difference model is
developed, calibrated and verified for three estuaries along
the central Oregon coast. The model is used to generate controlled
data for a large number of hypothetical estuaries.
Two non-dimensional coefficients, K[subscript F], and. K[subscript I], are developed
incorporating physical characteristics of the estuary which
summarize the effects due to friction and inertia, respectively,
These coefficients are used to explain the variability of tidal
response throughout the complete range of hypothetical estuaries
investigated. A predictive algorithm based on the derived
relationships is presented and examples of its application to
real estuaries is given.
The results of this study can be used to predict modifications
in tidal response due to proposed physical changes in an
estuary, such as entrance dredging or filling of tidal flats.
Field data of velocity, temperature and salinity for the
Yaquina, Alsea and Siletz estuaries is included with the paper.

▼ The distributions of the semi-major axes and masses of close-in planets (planets within 0.1 AU of their host stars) provide clues to their origin. Over billions of years, the mass and orbital distance are constantly evolving.
Tidal forces and atmospheric mass loss, driven by stellar ultraviolet flux, can influence the observed planetary distribution. Coupling these effects can lead to a greater understanding of how the observed distribution was shaped and may help to explain the gaps in the distribution of mass and semi-major axes for these close-in planets.
To study the effects of mass loss and tides, we applied a numerical model to many hypothetical populations of close-in planets and compared these hypothetical populations to the observed population. The evolutionary paths determined by the model depend on two as of yet poorly-constrained factors: the
tidal dissipation factor (Q*) and the heating efficiency (ε). By statistically comparing the observed distribution of close-in exoplanets with the hypothetical population, modeled under different ε and Q'* conditions, these values are tested. Under all conditions the two populations were statistically dissimilar, indicating that the population was either not initially evenly distributed, or that there is another important factor in planetary evolution.

▼ Braided rivers are complex, fascinating fluvial pattern, which represent the natural state of many gravel and sand bed rivers. Both natural and human causes may force a change in the boundary conditions, and consequently impact the river functionality. Detailed knowledge on the consequent morphological response is important in order to define management strategies which combine different needs, from protection of human activities and infrastructures to preservation of the ecological and biological richness. During the last decades, research has made significant advance to the description of this complex system, thanks to flume investigations, development of new survey techniques and, to a lesser extent, numerical and analytical solutions of mathematical models (e.g. Ashmore, 2013). Despite that, many relevant questions, concerning the braided morphodynamics at different spatial and temporal scales (from the unit process scale, to the reach scale, and eventually to the catchment scale) remain unanswered. For example, quantitative analysis of the morphological response to varying external controls still requires investigation and needs the definition of suitable, stage-independent braiding indicators. In addition, the morphodynamics of the fundamental processes, such as bifurcations, also needs further analysis of the driving mechanisms. General aim of the present study is to develop new methods to exploit, in an integrated way, the potential of the new possibilities offered by advanced monitoring techniques, laboratory models, numerical schemes and analytical solutions. The final goal is to fill some gaps in the present knowledge, which could ultimately provide scientific support to river management policies. We adopted analytical perturbation approaches to solve the two-dimensional shallow water model; we performed laboratory simulations on a large, mobilebed flume; we analysed existing topographic measurements from LiDAR and Terrestrial Laser scanning Devices; and we simulated numerically the river hydrodynamics. Within each of the six, independent, research chapters, we interconnected results from the different approaches and methodologies, in order to take advantage of their potential. Summarising, the more relevant and novel outcomes of the present work can be listed as follows:(i) We explored the morphological changes during a sequence of flood events in a natural braided river (Rees River, NZ) and we proposed a morphological method to assess the sediment transport rate. In particular we propose a semi-automatic method for estimating the particles path-length (Ashmore and Church, 1998) on the basis of the size of the deposition patches, which can be identified on the basis of DEM of differences. Comparison with results of numerical simulation confirmed that such an approach can reproduce the response of the bedload rate to floods of different duration and magnitude. (ii) We developed a new indicator of the reach-scale morphology and, on the basis of existing laboratory experiments, we explored its dependence,…

▼ Tidal barrages could contribute to mitigating climate change, but their deployment is not without potential welfare costs attributable to the degradation of ecosystem services. Economic valuation of natural resources provides a common metric for quantifying the disparate costs and benefits of barrage construction in a way that provides transparency when trade-offs are considered. However, very little is currently known about the value of environmental impacts associated with tidal barrages. Using the Taw Torridge estuary in North Devon as a case study, this research proposes an Environmental Benefits Assessment methodology that supports application of the ecosystem services concept to local environmental impact appraisal, and facilitates economic valuation. This methodology is novel in that it evaluates benefits, as opposed to services, and considers a comprehensive suite of benefits in a single assessment: an approach rarely attempted in practice, but essential if ecosystem services approaches are to fully support resource management needs. The subsequent empirical valuation uses stated preference techniques to examine the different ways people use and value the estuary ecosystem, determine how strongly they rank different costs and benefits of tidal barrages, and elicit willingness to pay (WTP) to reduce the habitat loss resulting from a tidal barrage development. The study provides the first empirical valuation of UK estuarine mudflats, but makes a further contribution to the environmental economics discipline by deploying both contingent valuation and choice experiment methods. Additionally, a novel application of the Analytic Hierarchy Process (AHP) is used to examine the consistency of WTP with expressed preferences for habitat protection in relation to other barrage attributes. The alternative stated preference techniques result in comparable WTP values and the importance attached to habitat loss (as measured by the AHP) is strongly associated with WTP and also with its scope sensitivity, indicating that WTP is largely driven by environmental preferences.

▼ Every marine energy source presents advantages and disadvantages. For example, they are not atthe same stage of maturity. Tidal range power is fully mature but the limited number of sitesavailable, combined with the large environmental impacts and investment costs limit itsdevelopment. The idea of artificial lagoons that will be offshore tidal range plant could create a newinterest for this technology. But for the moment, no plant of this type has been constructed yet. Tidalstream power is the next mature technology of marine energy after tidal range. Its development willrequire public subsidies but is supposed to be commercial in 2015. Systems are already indemonstration in several countries (UK, France and Canada). Wave power is less mature but it willbenefit from the development of tidal stream power and will probably be commercial in 2020. Somesystems are also in demonstration but challenges seem greater in wave power than in tidal power.Wave power conversion systems have to extract energy from the waves, even the largest ones, butat the same time resist to them. Contrary to tidal stream which has a predictable resource, waves areway less predictable and systems will have to be able to resist and valorize waves. OTEC (OceanThermal Energy Conversion) has been studied for years but it is still not mature. Its development forelectricity production needs technology research to develop cheaper and more compact systems(heat exchangers, pipes…). Air conditioning applications are developing and also require the use ofpipes and heat exchangers. Advances in this utilization could maybe help the development of OTECsystems for electricity production. Osmosis is the less mature and the most challenging technology. Atechnological breakthrough in the membrane could allow a rapid development. This breakthroughwill probably come from other sectors so it is important for the industries to get ready in order todevelop the system as soon as this technological improvement will be made.

▼ Four different composite material systems are subjected to nine months of in situ exposure at a potential tidal energy site. These four systems are fiberglass/epoxy, carbon fiber/epoxy, fiberglass/vinylester, and carbon fiber/epoxy pre-preg system. The loss of shear modulus due to this exposure is observed and these values are compared to unexposed samples of these same material systems. The measured reduction in shear modulus of the four systems following nine months of in-situ exposure is 66%, 26%, 13% and 7% respectively. In addition, three panels of the fiberglass/vinylester system are exposed to accelerated testing in the laboratory and the change in shear modulus due to this exposure is also calculated and compared. These panels lose 38%, 33% and 33% following 30 days of exposure to artificial saltwater at 30˚C, 40˚ C and 50˚C respectively. It is recommended that tidal energy device developers interested in using composites should focus future developmental efforts on fiberglass/vinyl ester composites, due to their low cost and reasonable long-term durability, or on carbon fiber/epoxy pre-preg, due to superior long-term durability.

▼ Internal gravity waves are complex oscillations widely found in fluids exhibiting density stratification, such as the ocean. Such waves may be produced by tidal currents flowing over rough seafloors; they are then called internal tides. As they travel away from the seafloor, internal tides tend to attain high amplitudes and break into turbulent eddies. Their ability to carry and dissipate part of energy make them of utmost importance in physical oceanography. Their intensive study in the past decades revealed that the breaking of internal tides may provide a large part of the power needed to mix the deep ocean and sustain the deep part of the meridional overturning circulation. The fraction of energy that those waves locally dissipate and the resulting vertical mixing distribution are crucial data for the parametrization of oceanic models, yet they remain poorly quantified. In this work, we provide the first estimate of the worldwide three-dimensional distribution of internal tide dissipation by means of large-scale numerical simulations. We couple linear wave theory with a simple nonlinear breaking scheme and use global topography, stratification and tidal current data to reproduce the generation, upward propagation and energy dissipation of internal tides. We show that exceptionally high dissipation is commonly attained at a few hotspots, confined above mid-ocean spreading ridges in the Southern Hemisphere. As expected by earlier studies, we find that a large part of the resulting mixing follows an exponential decay with height, with strong bottom intensities. We however show that substantial mixing over smoother flanks follows a so far unreported non-monotonic vertical profile with significant mid-depth maxima.

▼ A 2Dnumericalmodel is set-up for the tidal bore in the Sittaung River. This model is used to analyse the effect of the bottom friction, bathymetry, tidal range and river discharge on the propagation of the tidal bore. To obtain information about the tidal bore the Sittaung River is visited two times. During the second visit, depth measurements were carried out. It became clear that the tidal bore occurs only a few days after full and new moon at the village Kyaik Ka Thar. The tidal bore is also observed near Kyaik Ka Thar as an undular bore with a height of ± 0.3 m. Downstream in the estuary the tidal bore is larger and occurs 5 till 7 days after full and new moon. A numerical model is set-up for the region from Madauk till the Gulf of Marteban. The bathymetry is based on various datasets. Only a few cross-sectional profiles were available for the upper part of the model. The SRTMmap was used to determine the bottom slope of the river, whereas the cross-sections were used to determine the cross-sectional profile. From the depth measurements the initial depth for the bottom slope was obtained. The Navioncs webapp is used for the lower part of the domain (Gulf of Martaban). Both parts of the bathymetry were connected by using linear interpolation. From the Landat pictures the locations of the intertidal areas were obtained. As an upstream boundary a river discharge is set. A tidal signal is used as the downstream boundary. This downstream signal consists of two components: a daily double high water signal (D2) and a daily quarter high water signal (D4). The calibration is based on the propagation of the tidal bore. When the water level changes are larger than 0.2 m within 2.5 minute it is assumed that the tidal bore has propagate through a grid cell. On this way, the model results could be calibrated with data obtained from the field. For verification the relation between the cross-sectional area and the tidal prism was checked. For the sensitivity analyse the bottom friction, tidal range, bathymetry and river discharge were varied in various simulations. From these results can be concluded that the river discharge has no influence on the tidal bore, whereas the other parameters has a significant effect on the tidal bore. This implies that damming the Sittaung River, resulting in a change of the discharge, will not affect the tidal bore. Thus, changes of the propagation are only caused by the geometry and bathymetry of the estuary. Secondly the variety of the tidal bore is only caused by the tidal range, because this is the only parameter which change throughout the year. At least the effect of the tidal bore on the erosion is checked, but it is very difficult to relate the tidal bore to the erosion due to the lack of data. Upstream in the estuary the tidal bore is a small undular bore, which will not cause must erosion. Downstream of the estuary the tidal bore is larger and could have much more effect on the erosion.

▼ This thesis examines methods for designing and analyzing kinetic turbines based on blade element
momentum (BEM) theory and computational
fluid dynamics (CFD). The underlying goal of the
work was to assess the potential augmentation of power production associated with enclosing the
turbine in an expanding duct. Thus, a comparison of the potential performance of ducted and
non-ducted turbines was carried out. This required de ning optimal turbine performance for both
concepts. BEM is the typical tool used for turbine optimization and is very well established in
the context of wind turbine design. BEM was suitable for conventional turbines, but could not
account for the influence of ducts, and no established methodology for designing ducted turbines
could be found in the literature. Thus, methods were established to design and analyze ducted
turbines based on an extended version of BEM (with CFD-derived coe cients), and based on CFD
simulation. Additional complications arise in designing
tidal turbines because traditional techniques
for kinetic turbine design have been established for wind turbines, which are similar in their principle
of operation but are driven by flows with inherently different boundary conditions than
tidal currents.
The major difference is that
tidal flows are bounded by the ocean floor, the water surface and channel
walls. Thus, analytical and CFD-based methods were established to account for the effects of these
boundaries (called blockage effects) on the optimal design and performance of turbines. Additionally,
tidal flows are driven by changes in the water surface height in the ocean and their velocity is limited
by viscous effects. Turbines introduced into a
tidal flow increase the total drag in the system and
reduce the total flow in a region (e.g. a
tidal channel). An analytical method to account for this was
taken from the eld of
tidal resource assessment, and along with the methods to account for ducts
and blockage effects, was incorporated into a rotor optimization framework. It was found that the
non-ducted turbine can produce more power per installed device frontal area and can be operated
to induce a lesser reduction to the flow through a given
tidal channel for a given level of power
production. It was also found that by optimizing turbines for array con gurations that occupy a
large portion of the cross sectional area of a given
tidal channel (i.e.
tidal fences), the per-device
power can be improved signi cantly compared to a sparse-array scenario. For turbines occupying
50% of a channel cross section, the predicted power improves is by a factor of three. Thus, it has
been recommended that future work focus on analyzing such a strategy in more detail.

Reynolds stress and turbulent kinetic energy (TKE) density in a coastal
tidal channel.
The velocity profiles have been used to reveal the existence of a log-layer. The
data collected with the ADCP have been combined with fine- and microstructure
data collected with a moored instrument (TAMI) to examine the TKE budget and turbulence characteristics in
tidal flows.
The ADCP was rigidly mounted to the bottom of the channel and the instrument
was set to rapidly collect samples of along-beam velocities. In the derivation of the
mean flow vector and the second-order turbulent moments, one must assume that the
mean flow and turbulence statistics are homogeneous over the distance separating
beam pairs. A comparison of the estimated mean velocity against the “error” velocity
provides an explicit test for the assumption of homogeneity of the mean flow. The
number of horizontal velocity estimates that pass a simple test for homogeneity increases
rapidly with increasing averaging distance, exceeding 95% for distances longer
than 55 beam separations. The Reynolds stress and TKE density are estimated from
the variances of the along-beam velocities. Doppler noise causes a systematic bias in
the estimates of the TKE density but not in the Reynolds stress. With increasing
TKE density, the statistical uncertainty of the Reynolds stress estimates increases,
whereas the relative uncertainty decreases. The spectra of the Reynolds stress and
the TKE density are usually resolved; velocity fluctuations with periods longer than 20 minutes
contribute little to the estimates.
Stratification in the channel varies with the strength of the
tidal flow and is weak below mid-
depth. The ADCP measurements provide clear examples of secondary circulation, intense up/down-
welling events, shear reversals, and transverse velocity shear. Profiles of the streamwise
velocity are fitted to a logarithmic form with 1% accuracy up to a height, defined as the height
of the log-layer, that varies tidally and reaches 20 m above the bottom during peak flows of 1 m
s ⁻¹. The height is well predicted by 0.04u*/ω, where u * is the friction velocity and ω is the
angular frequency of the dominant
tidal constituent. The mean non-dimensional shear, [special
characters omitted],is within 1% of unity at the 95% level of confidence inside the log-layer.
Estimates of the rates of the TKE production and dissipation, eddy viscosity and diffusivity
coefficients and mixing length, are derived by combining measurements with the ADCP and TAMI
located at mid-depth. Near the bottom (z = 3.6 m), the production rate is 100 times larger than
all other measurable terms in the TKE equation. Hence, the rate of production of TKE must be
balanced by dissipation. The observed rate of production is proportional to the rate of
dissipation calculated using the observed TKE density and…

▼ Two exotic modes of collective excitations of
nuclei have been investigated in this work: the multiphonon
excitations in the vibrational nucleus,
102Pd and the phenomenon of chirality in the
133Ce nucleus. The vibrational yrast states
in
102Pd are described semiclassically as
quadrupole running (“tidal”) waves on the surface of the nucleus,
and the propagating
tidal wave interpreted as a rotating condensate
of interacting, spin-aligned d bosons. The
tidal wave concept has
been investigated experimentally by measuring lifetimes of levels
in the yrast band of the
102Pd nucleus using
the Doppler shift attenuation method (DSAM). The extracted reduced
transition probabilities, B(E2), for the yrast band display a
monotonic increase with spin, in agreement with the interpretation
based on rotation-induced condensation of aligned d-bosons, and the
observed constant B(E2)/J ratios imply that the gain in angular
momentum originates from the increase of the wave amplitude
(deformation). In the second investigation, two distinct sets of
chiral-doublet bands based on the three quasi-particle
configurations

(lower-energy, positive parity) were identified in the nucleus
133Ce. The properties of these bands were
observed to satisfy the established fingerprints of nuclear
chirality and were found to agree with results of calculations
based on a combination of the constrained triaxial relativistic
mean field (RMF) theory and the particle-rotor model. They
constitute a multiple chiral doublet (MχD), a phenomenon first
predicted by RMF calculations. This study has provided the first
experimental evidence for the existence of the MχD phenomenon, that
represents, in general, a confirmation of triaxial shape
coexistence.

▼ The tidally-influenced fluvial zone (TIFZ), or ‘fluvial-tidal’ transition, is an environment characterized by unidirectional fluvial, bidirectional
tidal, and oceanic oscillatory currents. TIFZ environments (i.e., deltas to estuaries) occur everywhere rivers meet ocean basins, and thus are important to understand from a geomorphological, morphodynamic and sedimentological perspective. However, most of the few existing studies of modern TIFZs have investigated a single region within a TIFZ, or relied heavily upon sediment cores and/or trenches. A large percentage of current knowledge of TIFZs thus comes from ancient outcrop studies, where the boundary conditions of the environments being studied are unknown. Therefore, most sedimentological models of TIFZs are built upon interpretations and qualitative discussions, and not via direct observations. There is thus a need to systematically investigate modern TIFZs using geophysical data collection techniques beyond sediment cores and/or trenches, in order to refine current sedimentological models with observations made within the context of known boundary conditions. The aim of this research is therefore to integrate a number of geophysical datasets collected within two modern TIFZ environments: (a) the single-threaded lower Chehalis River, Washington, USA, and (b) the multi-threaded lower Columbia River (LCR), Oregon/Washington, USA, in order to characterize the morphology, sedimentology, and internal sedimentary architecture of the bedforms and barforms in these systems. These results will be used to further the current understanding, and sedimentological models, of single- and multi- threaded TIFZs.
New data are presented defining the large-scale TIFZ hydraulic environments along the lower Chehalis River using Power Spectral Density (PSD) and wavelet transform analyses of water elevation time series data. These findings were used to provide a large-scale hydraulic context for sedimentological results/interpretations gained from (a) Ground Penetrating Radar (GPR), (b) Parametric echosounding (PES) sub-bottom profiling, (c) shallow (≤ 5m in depth) vibracores, and (d) time series of aerial imagery of point-bar deposits across the lower Chehalis River TIFZ. These results show that point-bars located within the fully-fluvial to mixed
tidal-fluvial regimes undergo relatively rapid laterally-oriented migration (> 1.5 myr-1), and possess an internal alluvial architecture consisting of lateral-accretion packages composed of continuous vertically-stacked sets of parallel strata. However, point-bars located within the tidally-dominated, fluvially-influenced regime experience relatively slow laterally-oriented migration (< 1.5 myr-1), and possess an internal alluvial architecture consisting of lateral-accretion packages composed of discontinuous- or chaotically- bedded vertically-stacked sets of strata. These vertically-stacked discontinuous strata are the product of bidirectional
tidal-current reworking of initially deposited parallel strata.

▼ Abstract
The Tanshui river is the second largest of the rivers in Taiwan, including three major tributaries, Da-han stream, Shin-dian stream and Keelung river. The large fresh water outflow induced strong stratification of the estuary and coastal region. In this region of fresh water influence (ROFI), the flow is dominated by barotrophic tide, with modification of density induced baroclinic flow.
This research tries to explore the variations of vertical structure of
tidal current. The causing of the changes will be discussed based on hydrodynamic parameters. Data used include a year long bmADCP records and sea level elevations. The sampling period is Septemper 24 of 2003 to July 12 of 2004. The sampling site is 4km offshore of river mouth. Additional data are winds, precipitation, solar radiation (from CWB) and river discharge (from RMO).
The results of analysis show that (1) strong flow during spring may induce large
tidal ellipse, while the ellipticity degenerates during neap. (2)
Tidal ellipticity increases when large freshwater discharge which induced strong stratification at the surface 1~ 2 meters. (3) Wind is a minor factor of ellipticity, even during strong wind over 10 m/s. (4) Influence of solar radiation and seasonal variation of
tidal ellipticity is insignificant.
In summary, the analysis indicates that the vertical structure of
tidal current is modified by (1) spring- neap tide (2) freshwater discharge and (3) winds. Especially, during spring tide with large river outflow, the
tidal ellipticity increase significantly due to frictional effect and vertical stratification.

▼ Tauw bv proposes
tidal creek restoration to bring back the tide into the upland area of
Zeeland in a safe and controllable manner. This will positively contribute to the Water
Framework Directive, ecological values and attractiveness of the region. However
tidal
creek restoration may also lead to negative effects on the surrounding land use, current
knowledge is merely focused on the success rate of the ecological restoration. Within
this research a framework has been developed to evaluate locations for
tidal creek
restoration, based on the effects on the surrounding land use. This framework will be
used to evaluate three locations, Zierikzee, Colijnsplaat and Sint Maartensdijk, which are
selected by Tauw bv.
The framework is mainly formed by a literature study and expert meetings, and handles
the relevant factors concerning evaluating locations for
tidal creek restoration: safety
preconditions and wishes of stakeholders, show the possibilities and restrictions for
tidal
creek restoration. The lateral extent of groundwater fluctuations and salinity intrusion
combined with their valued effects and the surface area of the affected types of land use
are the criteria which show the impact of
tidal creek restoration on the surrounding land
use.
The preconditions in the Netherlands are set by “Wet op de Waterkering” of 1996 and
“Waterwet” of 2009 (www.wetten.overheid.nl). In order to ensure these safety standards,
the incoming tide via the
tidal creek needs to be controlled and damped by water
constructions.
Tidal creek restoration with the help of a water construction diminishes the
wave energy, so the
tidal energy is the most important factor from the
tidal regime. The
wishes of the stakeholders are set by expert meetings
To predict the lateral extent of groundwater fluctuations and salinity intrusion, landscape
analysis is needed to find the relevant parameters. The lateral extent of groundwater
fluctuations depends on whether the adjacent aquifer is a confined or unconfined
aquifer. Unconfined aquifers (Colijnsplaat; ± 200 m) showed a far less extent of
groundwater fluctuations compared to the confined aquifers (Zierikzee, Sint
Maartensdijk; ± 1,000 m). All the locations showed that the amplitude of the groundwater
fluctuations decreases exponentially with the distance. The lateral extent of the intrusion
of salinity is not depended on locations characteristic, only on the
tidal period (which is
the same for all the three locations), and has a fixed distance of 60 meters.
The value of the effect is depending on the land use type, which for Zeeland ca be
divided in the following groups: urban areas, agriculture and nature areas. Groundwater
fluctuations have especially a negative influence to wooden foundations of constructions
in urban areas, due to bacterial decay. The most prominent negative effects of an
increase in salinity are on agriculture and most terrestrial nature areas as forests. Finally
a quantification of the surface area of a certain land use type with the given valued effect
is needed as it makes it…
