▼ The mangrove Avicennia marina var. australasica is rapidly colonising intertidal sandflats within a number of estuaries of the North Island of New Zealand. Many local residents perceive this change to be detrimental to the ecology and aesthetics of their estuaries, yet little empirical data is available to support these perceptions. Coastal managers are presently developing management strategies associated with either the maintenance or the removal of mangrove habitat with limited information available to predict the impacts of either course of action. This study was developed to investigate the physiognomic characteristics of the mangrove stands, and the physical and ecological impacts of their expansion within three embayments of Tauranga Habour: Welcome Bay, Waikareao Estuary and Waikaraka Estuary. Removal of mangrove vegetation within Waikaraka Estuary provided an ideal site to assess the physical changes that occur in response to this activity. Detailed field measurements of plant physiognomy of the mangroves within Welcome Bay, Waikareao Estuary and Waikaraka Estuary identified a limited vertical growth of < 10 cm per year, resulting in mean plant heights < 1.5 m. The climatic conditions limiting plant growth appeared to also limit the development of below-ground biomass (root mass). The 2 to 4 kg per m-2 of mangrove biomass under mangroves within Waikaraka Estuary is one of the lowest reported to date. Some mangrove sites within Tauranga Harbour produced pneumatophores at densities of ~ 700 m-2. This high density of pneumatophores increases the structural complexity of the substrate which was found to dampen the strength of tidal currents, in turn promoting sedimentation and limiting sediment re-suspension. The morphological reflection of this process was measured using Rod Surface Elevation Tables (RSETs), buried base plates, erosion pins and sediment traps. Typically surface sediments within mangrove colonies were mud-dominated, and sedimentation provided substrate accretion up to 21 mm yr-1 in the upper reaches of the study sites. Substrate accretion was also observed on un-vegetated sandflats in some upper-estuary and mid-estuary locations which may promote continued mangrove colonisation by elevating topography relative to the lower elevation limits for seedling survival of between 0.0 and 0.3 m MSL. A perception that mangrove colonisation has displaced bivalve populations was disproved in this study, at least within the upper estuary environments. A similar suite of benthic macro-invertebrates were encountered within both the mangrove and the un-vegetated tidal flat habitats. These benthic communities were dominated by deposit-feeding organisms such as polychaetes, and an absence of bivalves was common across both habitats. Approximately one hectare of above-ground mangrove vegetation (10% of the total coverage) was removed from Waikaraka Estuary between 2005 and 2007, which resulted in a lowering of the surface topography at average rates of 15 to 17 mm yr-1. Some textural change of the surface… Advisors/Committee Members: Healy, Terry R (advisor).

▼ Large volumes of aeolian sand and dust are deflated from unconsolidated till deposits, and supraglacial debris surrounding McMurdo Sound, Antarctica. This material is transported offshore with windblown snow onto extensive winter-formed sea ice in the southwest Ross Sea, and is subsequently released into the water-column during summer sea ice breakup. Aeolian sediment samples were collected from a ~600 km² area of sea ice in western McMurdo Sound to determine the magnitude of deposition and identify sediment sources. A new 2-dimensional numerical aeolian sediment transport model (NaMASTE) tuned specifically for the McMurdo Sound area, was used to explore the ability of the local wind system to move sediment from source areas to sea ice and to determine the pattern and extent of aeolian sediment dispersal to the southwest Ross Sea. Debris deposits on the McMurdo Ice Shelf debris bands are the most dominant sediment source for the area. Unconsolidated deposits between Cape Bernacchi and Spike Cape, and the Taylor Valley mouth are significant secondary deposits. Mass accumulation rates varied between 0.15 g m⁻² y⁻¹ and 54.6 g m⁻² y⁻¹, equating to a background aeolian sediment accumulation rate, excluding extremely high values, of 1.14 ± 0.59 g m⁻² y⁻¹ for the McMurdo Sound coastal sea ice zone. This is 3–5 orders of magnitude more than global background dust fallout for the Ross Sea. Modal grain size is very-fine sand to coarse silt. Notably, much of this material is distributed in localised, high sand content plumes that are oriented downwind from source, with finer deposits found outside these zones. An average seafloor linear sedimentation rate of 0.2 cm ky⁻¹ is calculated for McMurdo Sound, which is minor compared to biogenic sedimentation for the region. This equates to ~0.7 Gg y⁻¹ aeolian sediment entering McMurdo Sound during sea ice melt. Application of NaMASTE successfully simulated the general aeolian sediment distribution pattern. Testing of model variables suggests that aeolian material is mainly transported during strong (>20 m s⁻¹) wind events. Modelling also suggests aeolian material from McMurdo Sound can be transported north to the Drygalski Ice Tongue, ~250 km from source, but only in very trace quantities.

▼ The Tauranga Harbour is a mesotidal lagoon that is actively infilling with sediment. The southern basin of the harbour is important from both ecological and socio-economic standpoints. An understanding of sediment dynamics is necessary for the management of the harbour. Previously, the Tauranga Harbour Sediment Study (THSS) analysed the terrigenous flux of sediments into the harbour. It identified predominantly silt-sized sediment yields, from catchments, which remains confined to entry points into the harbour, or get exported out to the open coast. However, mapping of the tidal inlet and parts of the Western Channel through to Rangiwaea Island, has identified that accretion involves sand-sized sediment. The presence of eroding cliffs has provided speculation that sediment is primarily derived by local source erosion, as opposed to terrestrial or marine inputs. However, little is known about the sediment dynamics through the central harbour region. This thesis involved seismic reflection surveying through the Western Channel, from Rangiwaea Island to Matakana Point, utilising a Knudsen Sub-Bottom Profiler that operates on a chirp sonar system. Through the seismic analysis, patterns of sandwave occurrence were analysed to discover how sediment dynamics varied along the Western Channel. Additionally, three fault sites were identified in the seismic profiles. Two of these faults occur parallel to a previously mapped fault at Omokoroa, where doming has been suggested. The third fault occurs in the southeast where subsidence has been identified. Vibracoring was utilised to collect intact, contiguous, and undisturbed cores through the field area. Sand is identified as the primary contribution to ongoing sedimentation in the harbour. A general coarsening trend of sedimentary texture is observed from the central intertidal flats through the upper Western Channel towards the tidal inlet. This pattern is disrupted where current amplification or close proximity to a sediment source is associated with the accretion of coarser sediment to form sandwaves. Rates of sedimentation through the Western Channel over the last 7,200 years, ranged from 0.0482 mm/yr approaching the tidal flats, to 0.436 mm/yr where extensive sandwave were identified. A sedimentation rate of 0.0977 mm/yr was calculated within the channel where no sandwaves were present. The primary source of sediment appears to be local erosion of coastal cliffs, with sedimentation rates strongly correlating to erosional sites.

▼ In Zambia, the need to conserve water resources through technologies that can easily be managed by the local communities has resulted in the construction of small dams. However, small dams are adversely impacted by sedimentation due to soil erosion in the catchment area. The aim of this study was to assess the water storage capacity loss for the selected small dams due to sedimentation in Lusaka Province. The studied small dams were; Lwiimba, Silverest, Morester and Katondwe dam. Data was collected by bathymetric survey for each small dam using hydrographic boat with echo sounding. The shape and area of each reservoir were determined by mapping reservoir perimeter with a boat equipped with DGPS, by taking several position points along the shore line. The initial storage capacity data were collected from the dam owners and through interviews with three key informants on the effects of sedimentation on dam uses and on the existence of sediment control measures. Analysis of data involved determination of reservoir surface area and storage capacities using the Area and Volume tool under ArcGIS 3-D Spatial Analyst. The deposited sediment volume was estimated by subtracting the measured storage capacities from the initial storage capacities of reservoirs. Thematic analysis was applied in analysing the effects of sedimentation on dam uses and the existence of sediment control measures. Results of the study revealed that the measured reservoir storage capacities for Lwiimba, Silverest, Morester and Katondwe dams were 101,051.43 m3, 368,331.5 m3, 14,724.32 m3 and 10,714.88 m3, respectively. The estimated sediment volumes equivalent to storage capacity loss for each dam were; Lwiimba (99,044.57 m3), Silverest (379,480.5 m3), Morester (13,805.68 m3) and Katondwe dam with 9,937.12 m3.The accumulation of these sediment volumes have led to capacity losses, drying of reservoirs especially in the dry season and reduced life spans of the dams. The estimated rates of sedimentation for Silverest dam was found to be 14,595.40 m3yr-1. At this rate, the reservoir lifespan was 26 years; Lwiimba (2,200.99 m3yr-1), with the lifespan of 46 years; Katondwe (283.92 m3yr-1), 38 years, and for Morester dam the rate was 251.01 m3yr-1 giving a lifespan of about 58 years. Natural vegetation cover was found to be the main sediment control measure used in the catchments to reduce sediment deposition by runoff. It is concluded that the studied small dams are seriously affected by high rates of sedimentation from the time of their construction. This calls for periodic dredging of deposited sediment in small dams in order to increase reservoir storage capacity for sustainable use of the water resources. More sedimentation studies need to be conducted in Zambia.

▼ Colloidal crystallization in sedimenting systems is an incompletely understood process, where the influence of interparticle forces on the three-dimensional (3-D) microstructure remains to be fully elucidated. This dissertation outlines work that is intended to improve our knowledge of this subject by studying sedimentation equilibrium and phase behavior for electrostatically repulsive systems, as well as the interfacial crystallization of attractive depletion systems. Towards this end, several analytical and experimental tools have been developed to explore the thermodynamic behavior of these systems. For example, the experimental challenges necessitated the development and implementation of the following in this work: (1) core/shell silica particles incorporating molecular fluorophores or semiconductor nanocrystals; (2) modification of silica particle surfaces; (3) the design of specialized sedimentation cells; and (4) the development of a novel fluorescent intensity-based approach to quantifying colloidal sediments. Analysis of the experimental data required the use of the following tools: (1) location of particle centers from images; (2) deconvolution of intensity profiles using a novel Monte Carlo-type algorithm; and (3) prediction of colloidal phase diagrams using perturbation theory. On the basis of this work?s experimental and simulation data, it is concluded that competing orientations of crystal grains may suppress crystallization at grain boundaries, resulting in a non-uniform depth of the fluid/solid transition. Also, it was demonstrated that the grain size in depletion crystals formed from quantum dot-coated silica particles can be increased by localized annealing with the confocal microscope?s laser. Additional findings include the ability of the intensity-based approach to measure interparticle forces in colloidal sediments, as well as the inability to use perturbation theory to predict two-dimensional colloidal fluid/solid transitions. While significant progress has been achieved, work on 3-D imaging of colloidal depletion crystals in a refractive index-match medium is ongoing. This work improves our understanding of 3-D colloidal crystallization at interfaces, as well as provides new tools for future research. Also, this work demonstrates a potential route for zone refining of colloidal crystals, a technique that may be important in the search for low-defect 3-D arrays that can be used as templates for photonic bandgap materials.

▼ Excess sedimentation began affecting the wetland dynamics of Pine Gully in Seabrook, Texas during the first quarter of 2004. This sedimentation was sudden and became a serious problem for the dynamics of the Pine Gully wetland because the fine, well sorted, quartz rich sediments began plugging the main channel of the previously tidally dominated wetland. Progressive sedimentation has produced overbank deposits in the marine grasses, contributing to the death of wetland grasses by sediment chocking. The main purpose of this study is to determine the new source and mechanism of sedimentation in Pine Gully, document changes from sedimentation, and determine a solution to prevent future sedimentation. Sedimentation in Pine Gully and coastal areas adjacent to Pine Gully has occurred in a region that has experienced subsidence and sea level rise. The sedimentation in Pine Gully is a direct result of new and sustained sediment at the mouth of Pine Gully. These new sediments are transported into Pine Gully by displacement waves from ships moving through the Houston Ship Channel. Beach renourishment at Wright Beach, located a half mile north of Pine Gully, occurred as Pine Gully experienced sedimentation. Construction of a breakwater at the mouth of Pine Gully and subsequent removal of sediment in Pine Gully itself is ultimately the solution to revitalizing the wetland to its pre-sedimentation state. Replanting of native vegetation killed off by sedimentation is recommended and would hasten the recovery of the wetland. Documenting the effects of this unique sedimentation in Pine Gully has implications for the future. Beach renourishment or coastal projects that may contribute excess sediment to the coastline should be concerned with unintended effects they may cause. Although an historically eroding shoreline exists, the effects of excess sedimentation can be severe. A coastal study should be done before sediment is added to the shoreline to identify any areas within the sphere of influence of the project. Ecosystems determined to be within the sphere of influence by a coastal study should implement preventative measures at those locations to avoid an ecological disaster similar to that in Pine Gully.

▼ The Ninetyeast Ridge (NER) is a ~5000 km-long aseismic volcanic ridge trending NS in the eastern Indian Ocean basin. It is widely accepted that NER formed from the trace of a single hotspot as the Indian plate moved northward during the Late Cretaceous and Early Cenozoic due to the linear age progression from 43 Myo at the southern end to 77 Myo at the northern end. What is not fully understood is the geologic history of the ridge since its formation. This study examines the stratigraphy and sediment thickness on the ridge using new seismic data to describe the sedimentary history of NER. More than 3700 km of 2D multichannel seismic reflection profiles were collected along NER at seven sites between 5.5 degrees N and 26.1 degrees S during cruise KNOX06RR of the R/V Roger Revelle in 2007. Scientific objectives were to obtain site survey data for proposed drilling and to understand the sedimentary layers, sediment distribution, and geologic history of NER. Seismic survey sites were chosen primarily based on proximity to existing Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP) drill holes (Sites 758, 216, 214, and 253) for interpretation and correlation with existing lithologic data. Seismic data were processed (filtered, stacked, and time-migrated) and interpreted using standard seismic stratigraphy principles. Three major horizons were interpreted, correlated with those previously recognized at the DSDP and ODP sites, and traced throughout the seismic data. Seismic data were categorized into three units based on distinct acoustic properties including changes in reflector amplitude, wavelength, continuity, and geometry. Seismic Unit I comprises a succession of pelagic sediments and sedimentary rock draped over Seismic Unit II, which consists of pelagic carbonates mixed with volcaniclastics. Seismic Unit III is volcanic basement. Sediment layer thicknesses and distribution were mapped at each site, and bathymetric data were correlated with seismic data to interpret geologic features. Seismic and core data indicate a common sedimentary history at each site: volcaniclastic-rich sediments deposited during or shortly after ridge formation topped by a thick drape of pelagic sediments. This history likely happened in three stages over the last ~77 My: 1) the initial subaerial or submarine emplacement of the volcanic ridge, 2) the deposition of shallow water sediments and volcaniclastics, and finally 3) the subsidence of the ridge followed by deep water pelagic sediment deposition.

▼ The Carnegie Ridge is an aseismic ridge that bounds the south flank of the Panama Basin. Dynamic sedimentation around Carnegie Ridge is shown by evidence of erosion, dissolution and re-deposition of pelagic sediments where erosive episodes have carved out relict landscapes. I examine three aspects of these features: 1) What are the mechanisms involved in the erosive episodes; 2) Can the ages of the erosive events be constrained; and finally 3) Can the transport mechanism be identified? The extent of erosion and re-deposition was studied during the R/V Melville cruise MV1014 from October to November 2010 to compare with geochemical estimates of sediment focusing. The MV1014 cruise acquired geochemical, geological and geophysical data to compare with earlier surveys and scientific drilling. Large-scale erosion, presumably driven by massive, density-driven deepwater spillover events from the Peru Basin, created a prominent valley named Sand Dune Valley in the study area. A second, smaller valley, known as Western Valley, was likely formed by medium-scale erosion catalyzed by a ridge jump with subsequent normal faulting forming a fault scarp which has intensified near-bottom currents. Smaller-scale erosional events created small-scale surface sediment truncation. Utilizing a seismic stratigraphy developed by comparing seismic horizons to the sediment columns at DSDP Site 157 and ODP Site 846, and exposure of diagenetic chalk along the valley floors allowed a reconstruction of the timing of these highly erosive episodes. Two major erosive episodes are proposed to have occurred at ~5 Ma and ~3Ma which removed as much as 75 km3 of sediment. The erosive episodes may be linked to a ridge jump of the Galapagos hotspot at ~5-4 Ma and the final closing of the Isthmus of Panama ~3Ma. Sediment transport regimes for the Quaternary were determined using horizons dated at 2 Ma (PL-2), 1.7 Ma (PL-1) and 84 ka (Q-84). Isopachs created using the three horizons concluded that the dominant transport regime occurs to the NW of the study area with strong lateral transport to the sides of the valleys.

▼ Onshore-offshore and onshore wide-angle reflection and refraction seismic data are analysed in order to constrain the crustal P-wave velocity structure within Wanganui Basin and the southern Hikurangi margin, western North Island, New Zealand. Two, two-dimensional, P-wave velocity models are constructed using reflection and refraction phase travel-times based on forty-four onshore-offshore receiver gathers, twelve onshore shot gathers and two marine multi-channel-seismic reflection profiles collected along two transects within Wanganui Basin. The profiles are orientated both sub-parallel and perpendicular to the strike of the Hikurangi margin. Within Wanganui Basin, a north-south increase in Moho depth is resolved sub-parallel to the strike of the Hikurangi margin from 25 km depth north of Mt Ruapehu to 36.5 km within offshore Wanganui Basin at the latitude of Foxton. This increase is punctuated by an abrupt step in Moho depth of 7±3 km over a lateral distance of < 30 km from 25 km to 32 km depth slightly south of Mt Ruapehu. Perpendicular to the strike of the Hikurangi margin, the Moho is resolved at a depth of 35.5 km near the southern edge of the basin. A comparison between the Moho interpreted on multi-channel-seismic-reflection stacks and wide-angle reflection models suggests that the wider-angle Moho represents the highest amplitude reflector in a band of reflectivity that represents the Moho on the vertical incidence reflection stack. In this case, the Moho may be an extra ~ 5 km thicker than that determined in the wide-angle models. Nonetheless, these models confirm the crust in Wanganui Basin is anomalously thick, yet may be thinner than the previously thought maximum thickness of > 42 km by up to 5 km based on wide-angle data. The Australian/Pacific plate interface is imaged as a relatively smooth surface at depths of 28.15 - 35.6 km between the latitudes of Paekakariki and Foxton with apparent dip to the north-north-east increasing from 2.3 to 9.5°. Perpendicular to the strike of the Hikurangi margin, this interface increases in depth from 16 - 33 km with an increase in dip of 5.4° beneath Featherston to 19° beneath central Wanganui Basin. P-wave velocities range between 5.8 - 6.5 kms-¹ in the upper ~18 km of the crust within Wanganui Basin. These are interpreted to represent mid and lower-crustal rocks that have been emplaced in the upper crust by exhumation during the Miocene. In the lower crust P-wave velocities are inferred as 6.5 - 6.85 kms-1 sub-parallel and 6.5 - 6.65 kms-¹ perpendicular to Hikurangi margin, suggesting a lower crustal P-wave anisotropy of up to ~ 3% This may reflect the preferential alignment of mineral fabrics in the direction of relative transpressive plate motion during the Neogene and/or structural anisotropy parallel to the strike of the Taranaki Fault Zone and Kapiti-Manawatu Fault System. The structure of the Pacific plate crust is resolved as two layers. The top layer is inferred as a low-velocity sediment sheet with a P-wave velocity of 5.00 - 5.20 kms-¹ and thickness… Advisors/Committee Members: Stern, Tim, Lamb, Simon.

▼ Eutrophication is the enrichment of water body by nutrients; especially nitrates and phosphates. These nutrients are used by phytoplankton such as algae and Cyanobacteria. High nutrient concentration cause algal bloom; if this is Cyanobacteria; it creates a big health problem to human and cattle depending on drinking water reservoirs by releasing toxic substance. This study investigates and quantifies the nutrients at Dire reservoir so that it is easy to identify the potential source of nutrients to the Dire reservoir which was constructed by Addis Ababa Water and Sewerage Authority for drinking water supply. Furthermore, the trophic status of the reservoir was identified in comparison to the amount of Chlorophyll-a. In doing so, Reconnaissance survey was made through systematic stratified sampling design where the soil, sediment and water in and around the reservoir and the tributaries flowing to the reservoir were sampled and analyzed in the laboratory for their nitrate and phosphate contents. A total of 22 waters, soil and sediment samples were taken for each of the sample types namely: water, sediment and soil in December and February, dry season. These were one from upstream and another from downstream of the tributaries flowing towards the reservoir such as Legedadi, Silmicha and Berek. In addition, five soil, five sediment and five water samples were taken inside and around the reservoir independently for the two months. The data obtained are tabulated to be analyzed using Microsoft Excel and SPSS software. Accordingly, analysis of variance and correlation of the parameters are evaluated. There is high nutrient deposition in the sediment compared to the soil and water; it is more concentrated at the downstream than the upstream of the tributaries which are an indication of erosion of upstream soil during the rainy season and aggravated by crop cultivation in the watershed. Surprisingly, the chlorophyll- a concentration (0.35μg/l) is not as much as the nutrients due to low light penetration. The reservoir is phosphorus limited and is hyper- eutrophic. The nutrients in the reservoir are mostly contributed by sediments of Legedadi (18.6mg/kg) and Silmicha (34.9mg/kg) Rivers. Hence, IWM must be applied by the stake holders paying attention to Silmicha followed by Legedadi and Berek tributaries. Advisors/Committee Members: Mekuria Argaw(Dr.) (advisor).

▼ Cone penetration tests (CPTs) have been developed for engineering investigations of sands and finer sediments. CPTs produce high resolution, repeatable and continuous records to depths of several tens of metres, and resemble wireline logs used in the petroleum industry. It is the objective of this dissertation to demonstrate that they can be used for facies analysis in a similar manner, by using these data to develop a facies model for the modern Fraser River delta, British Columbia, Canada. CPT data provide reliable estimates of sediment type and gram size, so that bed thicknesses, sharp and gradational contacts, coarsening and fining upward sequences, bed continuity and dips can be readily identified. The facies model of the Fraser delta is based on a database of over 800 CPTs and 20 continuously cored boreholes. These data demonstrate that the topset is dominated by a nearly continuous sharp-based sand unit that is 8 to 30 m thick, fines upward and is interpreted to represent a complex of distributary channel deposits. The widespread distribution of this sand unit is the result of distributary channel migration in a tidal flat setting and avulsion or channel switching in the upper delta plain. The sand unit is gradationally overlain by a thinner sequence of interbedded sands and silts deposited in tidal flat, abandoned channel and floodplain environments. Deposits of the upper foreset (<60 m) dip up to 7° seaward and are dominated by silts, interbedded and interlaminated with sands. Several intergradational facies, ranging from dominantly silt to dominantly sand, occur and represent increasing proximity to active distributary mouths. These sediments are organized into metre-scale sandy and silty coarsening-upward sequences that are interpreted to represent annual deposits, and sharp-based sand units that represent sedimentary gravity flow deposits. Deeper foreset deposits are dominated by bioturbated silts. The distribution of facies on both the topset and the foreset has been controlled by the interaction of tidal and fluvial processes. CPT data played a key role in developing this facies model of the Fraser River delta. Most facies have distinct CPT signatures. For example, the topset sand unit and overlying deposits have a CPT signature comparable to the “bell-shaped” gamma ray log signature typical of channel deposits. In the foreset, the seaward dips, the coarsening upward sequences and the sharp-based sands are readily observable on CPT data. Although cores were essential to confirm the facies significance of these signatures, the large volume of CPT data permitted recognition of facies distributions and relationships “at a glance” throughout the delta, rather than at the relatively few site where continuous cores were available. Furthermore, CPTs can be acquired for a fraction of the cost of continuous cores, so that CPT data are potentially an invaluable tool for stratigraphic investigations of other modern sedimentary environments dominated by sands and finer sediments.

▼ Embedding of subsea pipelines for protection purposes is usually done in a ‘Trench – Install – Backfill’ operation. The pipeline can also be embedded after it is installed on the seabed. This method is called post-trenching. When using a trailer suction hopper dredger for post-trenching, a large water jet erodes the soil underneath the pipe creating a temporarily trench in which the pipeline can sink. Large steel pipelines are inflexible and need a considerable free span to sink to the desired depth. The length of the trench is limited as the eroded sand that is brought in suspension starts to settle in the trench when the velocity of the suspension decreases. To be able to predict the length of the trench, the sedimentation velocity in jet induced flow is investigated in this research. The research describes the experiment series that is performed to investigate the behavior of a trench that is created by a vertical jet flow, trailing over a sand bed. The focus is on the sedimentation part of the trench. Concentrations and flow velocities are measured to determine the shape of the trench, the distribution profile and velocity profile. The experiments show a clear relation between the depth of the trench and the length that the trench is open. A deeper trench (due to a higher pressure or lower trail velocity) results in all experiments in a longer trench. The near bed concentration and the sedimentation velocity do not change a lot for different settings of the jet. To see if the theory on the sedimentation process can represent the post-trenching process, a calculation model is made that uses the theoretical concentration profile to calculate the sedimentation velocity. A good similarity was found between the model and the experiments. The experimental research on the sedimentation velocity in a trench that is created in a post-trenching process, indicates that sedimentation velocity is largely independent of the jet parameters. To make the trench longer, it has to be deeper to lengthen the path that the bed has to travel. A test with a second run over the bed proved highly effective due to the high porosity of the sand that settles in the first run, the maximum excavation depth is twice the depth of the first run. By implementing a pipeline in the experiment it is investigated if the pipeline has an influence on the flow conditions and sedimentation velocity.

▼ The study focuses on the impact of human interventions on the natural behaviour of estuaries in response to sea-level rise. In particular it focuses on the affect of managed realignment on the critical sea level rise (SLRcrit) for the Poole Harbour. Numerical model ASMITA (Aggregated Scale Morphological Interaction between a Tidal inlet and the Adjacent coast, Stive and Wang, 1996) is used to study the response of the system to the external forcing (both natural and anthropogenic). ASMITA model schematises the tidal-inlet system and characterises each model element by a single variable volume. Volumetric data of the Poole harbour inlet elements obtained through the digitisation of the historical admiralty charts was used to calibrate the model. The model assumes that the each inlet elements tends towards an equilibrium volume which can be defined using the empirical equations. These equilibrium equations consist of equilibrium parameters that depend on the regional properties like hydrodynamics and topography of the Poole harbour. Once the model is calibrated, simulations were performed with various sea level rise scenarios (historic and future SLR) to observe the natural behaviour of the Poole harbour. Managed realignment is being introduced in the model and a range of values of critical sea-level rise was obtained and compared with the predicted sea-level rise rate given in the literature for the next century. Results suggest that the “hold the line” management scenario (current situation) would not result in the complete loss of inter-tidal flats and the coastal flooding is unlikely to occur over the next century, as a result of critical sea-level rise values exceeds the predicted rate. However research suggests, introducing realignment (coastline retreat management scenario) reduces SLRcrit values for the estuary; thus making the estuary more sensitive to the predicted future SLR rates.

▼ Fairway Maintenance of the river Ijssel The inland trade is a very important economical activity in The Netherland. Therefore to maintain and improve waterways is a common activity. The main problems that threaten the safety in the shipping are the erosion and sedimentation on the banks, especially in the bend banks. So some studies are necessary to know the best method to avoid the sedimentation and erosion in these places. This study is focused in the effect of a sand trap in the River IJssel over the sedimentation and to try to answer questions about its effectiveness and if it is possible to find a better layout for the sand trap. To carry out this research is necessary to set-up a mathematical model which can reproduce the behaviors of the river and the sand trap. So a mathematical model has been built using the Delft3D software. So, the effectiveness of the original sand trap has been studied and three possible alternatives have been studied too. The alternatives are: - Two different sand traps with same volume of the original one, but shallower, longer than the original one and nearest to the sedimentation zone (alternatives A.1 and A.2). - Sand trap with more volume than the original one and nearest to the sedimentation zone ( alternative B). The results of this study show that the effect of the sand trap over the sedimentation in a bend located 2 km downstream of the sand trap is non-existent. Also the results show that the alternatives A.1, A.2 and A.3 are more efficient, it means that they catches more sediments, but they dont produce any effect over the sedimentation zone. To study the effect of a bigger sand trap and nearer to the sedimentation zone is necessary. Also it is recommended to improve the data about sediment transport, bed levels and discharges in the lower stretch of IJssel. These data will be necessary to carry out a better mathematical model.

▼ The northern sector of Waihi Beach is an example of chronic erosive tendency. The sediment deficit along the area of beach fronting the seawall means that there is often no beach at high tide. This existing situation, and the various remedial options suggested, has created an emotive issue for beach residents. Accordingly, the current study was undertaken to identify and evaluate the fundamental coastal processes impacting upon the erosion at northern Waihi Beach. Methods used to investigate this problem included: beach profiling and shallow water hydrographic surveying; mapping of sediments and the distribution of bedforms on the inner shelf using side-scan sonar, identification of nearshore sediment transport pathways from sediment textural analyses; collection and analysis of nearshore wave and current data; and numerical modelling of wave refraction and sediment transport processes. A side-scan sonar survey, ground-truthed by surficial sediment analyses and underwater video and diver observations, indicated that the shallow inshore zone is characterised by a relatively featureless seabed dominated by fine sands. Large shore-normal sand ridges (η=0.4-2.5 m, λ=300-1400), with crests oriented northeast to southwest were identified between 15-30 m water depth offshore northern Waihi Beach. These very pronounced features consist of coarse megarippled (η≈0.12 m, λ≈1 m) sediment. Sediment textural analyses revealed that offshore sediments vary from fine to coarse sand, showing a seaward-coarsening progression. Beach sediments consist of predominantly fine sands, with a slight inferred fining in grain size that occurs towards the northern end of the beach. This is possibly a result of lower wave energy when subject to swell and sea waves from the north, due to sheltering in the lee of Rapitiotio Point. 80 days of wave and current data were collected offshore northern Waihi Beach, during two separate deployments in Nov/Dec 2007 and May/June 2008. The summer deployment was characterised by waves from a northeast-east origin (Hs=1.09m; Ts=7.13s). Similar conditions were exhibited during the winter deployment (Hs=0.95m; Ts=6.79s). Observed relationships between wind direction and near-bed current direction, combined with calculated sediment entrainment rates, enabled predictions of the frequency of shoreward sediment transport by bottom currents to be made. Onshore currents, associated with winds from the southwest, prevailed during the deployment period. However, observed current velocities alone were generally incapable of inducing sediment motion. Analysis suggests that wave properties are likely to govern the frequency of sediment transport in the nearshore, as their presence is required to lift sediment into suspension for dispersal by ambient background currents. Onshore movement of sediment was estimated to be ~11,800 m3/year or 2.6 m3/m. Monochromatic wave statistics measured during the field study were used to calibrate a numerical wave refraction model. The wave refraction influence of Mayor Island…

▼ There are many small dams in Zambia constructed for the purpose of collecting and storing runoff from the catchments. The flow of water into dams is accompanied with sediment resulting from soil erosion within reservoir catchments. The deposition of sediment in reservoirs has implications for their sustainability and thus future water supplies. However, accumulated sediment in reservoirs can be dredged to extend the useful lives of dams. This study aimed at evaluating the burden of sediment and sedimentation in selected small dams in Lusaka and Southern provinces of Zambia. A survey research design was employed to gather data from the sampled dams in Lusaka and Southern provinces of Zambia. A cost-benefit analysis was performed to determine the cost and value of burden of sediment and sedimentation on selected six small dams. A Contingent Valuation of Willingness to Pay was conducted to find out the possibility of local peoples’ support of a possible programme of dredging the accumulated sediment in the reservoirs to restore the lost storage capacities. of the dams. The results of the study showed a clear scenario of the burden of sediment to local communities and the potential restoration of lost reservoir storage capacities to sedimentation. The study established that 25 - 52 percent of studied reservoirs initial water holding capacities had been lost to sediment accumulation in 26 – 60 years of dam operations. The rates of sediment accumulation ranged from 283.92 m3 yr-1 to 29,118.63 m3yr-1, indicating that the surveyed reservoirs had less than 60 years of useful lives beyond the year 2015. Sediment and sedimentation was found to lower the annual benefits from reservoirs intended water uses in monetary terms. The Net Present Value (NPV) for removing and selling the accumulated sediment was found to be high and positive for all the dams while the NPVs for operating reservoirs with sediment in them were found to be low and sometimes negative values were recorded. It is concluded that the studied small dams in Lusaka and Southern Provinces were experiencing severe sedimentation which lowers the benefits from intended dam uses. Because of the high potential benefits that could be derived from sediment, localcommunities and dam owners should be encouraged to exploit this abundant natural resource in their areas.

▼ Cultural eutrophication is caused by the excess addition of phosphorus to aquatic ecosystems, and has long been a water quality management issue in Lake Erie. Despite successful reductions in external loading of phosphorus in Lake Erie the in lake total phosphorus (TP) concentrations are increasing recently and symptoms of eutrophication are apparent. In this study I examined the sedimentation velocity of particulate phosphorus and how it is affected by stratification and plankton community composition over the growing season. Diatoms had the highest sedimentation velocities and a shift to slower settling species with greater form resistance (Synedra sp. and Fragilaria sp.) was observed during the stratified period possibly in response to the shallower mixed layer. No significant variation in sedimentation velocity was found with trap depth, plankton size or temperature; hence the individual plankton cells were employing methods to change their sedimentation velocity in accordance with changing environmental conditions. Phosphorus sedimentation was most closely related to silica sedimentation, which largely represents the sedimentation of the diatoms. Thus any shifts in community composition will affect phosphorus-settling rates. The sedimentation rate of phosphorus decreased from June 2nd until August 26th during the stratified period at station84 and from June 2nd to August 5th at station 452. The decline of total phosphorus was less than the sedimentation rate, hence, sediment resuspension and redistribution from the littoral sediments along with atmospheric deposition are important sources of phosphorus to the central and eastern basins of Lake Erie. The sedimentation rates of P, N and C did not follow the Redfield ratio. The sedimentation velocity of P was much less than that of C and N, indicating that P is conserved in the epilimnion and possibly that C and sedimentation contains more non-living material. Therefore, modelling phosphorus sedimentation after carbon and nitrogen sedimentation is inappropriate. Laboratory sedimentation towers can be used to measure phytoplankton sedimentation velocity including net upward movement, which traditional sedimentation traps are unable to do. Determination of the sedimentation velocity of the phytoplankton community to variables such as light, temperature and nutrient status, using this method, may eventually lead to a dynamic phosphorus model that could more effectively reduce eutrophication effects in Lake Erie.

▼ In many applications, it is desired to separate unwanted fine particulates from a liquid by gravity settling. An efficient separation, however, will be feasible only if a combination of aggregation and sedimentation occurs. To understand the kinetics of such a process, a mathematical model that accounted for aggregation and sedimentation was developed. The simulation was based on Smoluchowski’s equation of population balance, with the collision frequency determined by Brownian motion and differential settling, while treating the aggregates as fractal objects as the particles collide and aggregate. One of the most important issues here is that aggregating systems, especially those encountered in particle technology and separation processes, often involve non-uniform particle distributions. Situations with evenly distributed aggregates are very rare in practice, but this continues to be the “default assumption” in many theoretical treatments. This study addressed this issue by developing a series of experiments and numerical model to properly account for non-uniform particle sizes and their spatial variations. Our results showed that the rate of settling could be improved significantly if the particles aggregated (the settling time may be reduced from hours to minutes). Experimentally, we showed that, depending on the strength of interaction between the particles, different settling regimes were observed. It was also observed that under certain experimental conditions, an initial ‘induction time’ appeared before the apparent onset of sedimentation. It appears that the particles required some ‘waiting time’ before commencement of aggregation. Our simulations showed that the observed ‘induction period’ may in fact be a kinetic phenomenon that was independent of the nature of the inter-particle forces (i.e. on the microscopic scale, the particles began to aggregate immediately without any delay). Our simulation showed that inter-particle attraction could significantly affect the rate of aggregation and sedimentation. Larger attractive forces also resulted in a perceptible clear liquid-suspension interface; as such forces diminished, the clear liquid-suspension interface became more diffuse and eventually appeared as a gradual concentration gradient. A novel approach was used to predict formation of this ‘mud line.’ We have also demonstrated that sedimentation kinetics are largely insensitive to the initial particle size distribution; an explanation for this observation is discussed.

▼ The Brazos River, located predominantly within the state of Texas, has the highest water and sediment discharge of all rivers in the state, and ranks second behind the Mississippi River in terms of sediment load delivered to the Gulf of Mexico. This river is the only Texas river that consistently drains directly into the Gulf of Mexico forming a wave-dominated delta. The delta has experienced dramatic and rapid changes over the last 100-plus years. These changes have resulted from both natural and anthropogenic alterations to the coastal zone proximal to the river mouth and within the rivers watershed. By utilizing high-resolution geophysical data, sediment cores, water column data, and historic shoreline data this study investigated the mechanisms in which sediment is transported to the coastal ocean, the fate of that sediment as it becomes preserved in the modern geological record, and the evolution of a modern delta. Results from this study show that during for a majority of the time a salt-water intrusion in the lower river traps sediment, preventing export to the coastal ocean. The trapped sediment forms an ephemeral mud layer in the lower river that may be remobilized during increased river discharges. When river discharges increase above an observed threshold of 300 m³/s the salt wedge is pushed seaward of the river mouth and sediment is exported via a buoyant plume. As export of sediment is episodic, accumulation of sediment on the subaqueous delta characterized as non steady-state, and resembles typical foreset delta attributes. These include physical stratification of sediment layers, episodic but relatively high rates of accumulation, and little bioturbation. Currently sediment is primarily accumulating west of the river mouth, and the majority of sediment is bypassing the system. Over the history of the delta, changes both anthropogenic and natural have shifted the relative balance of fluvial sediment supply and marine sediment dispersal. These changes have resulted in dramatic changes in the shoreline, and phases of activation and abandonment of deltaic lobes, which can be seen through historical data and imagery, and is preserved in the recent sedimentary record.

▼ The investigation of the geological history (i.e., stratigraphy and sedimentology) and the dynamics of coal depositional environments, in particular, the forces responsible for changes in the accommodation space (e.g., subsidence vs. sedimentation rates) in the Permian coal-bearing Karoo strata in the Central Kalahari Karoo Basin (Botswana) revealed new details about the depositional processes and environments. Detailed review of the temporal and spatial stratigraphic variation of the coal-bearing Ecca Group successions via the analysis of facies changes based on core descriptions, gamma logs, field observations and palaeo-current measurements, lead to the identification of two main informal stratigraphic units, namely the Basal and Upper Units. The Basal Unit is characterised by an upward-coarsening succession, and it is interpreted as a product of a progradational deltaic setting (i.e., regressive deltaic cycle). This is followed by five sequences of fining-upward successions of sandstones and siltstones in the Upper Unit, interpreted as deposits of distributary channels (the basal arenaceous member) capped by finer argillaceous sequences of the deltaic floodplains (the upper coal-bearing member). The Upper Unit thus is interpreted as a delta plain facies association which was formed during transgressive phases when conditions for coal-quality peat accumulation (e.g., high water table) were present and the available accommodation space was partly controlled by tectonic uplift (repeated?) at basin margins. Limited palaeo-current analysis indicates deposition by channels flowing from the east, south-east and north-east. The lack of good quality exposures hampers the reconstruction of the plan form of the channel patterns. However, the little available evidence indicates a high-energy fluvio-deltaic system with irregular discharge and a high proportion of bedload sediments. Coal-seam thickness in the upper coal-bearing member reflect the complex control of the geological processes associated with and following peat formation, such as differential compaction of the underlying lithology, and the erosive or protective nature of the immediately overlying lithology.
