▼ Due to the importance of soil moisture in many fields of study, and given the sparsity of systematic research on radiative transfer features of moist soil in the optical domain, this dissertation focuses on both the spectral reflectance and transmittance features of dry and wet soils. In this work, the spectral reflectance and transmittance of soil are examined. The experiments lead to possible physical explanations for the spectral and directional features of reflectance spectra, and the results suggest how optical and proximal remote sensing might be useful in observations of soil moisture content. The first experiment considered the change in spectral reflectance of soil samples during evaporative drying. The water absorption band depths at 970 nm and 1160 nm, in near infrared, decreased monotonically as the water content decreased, but they were not detectable in all samples; these water absorption bands will not be generally useful for observing surface soil moisture. In contrast, the band depths of the 1440 nm and 1930 nm absorption features were very responsive to the water content over the entire drying cycle. The change in band depth at 1930 nm was particularly interesting since the direction of the change reversed simultaneous with soil water evaporation rate change. A simple mathematical model suggests that the pattern of change in the band depth is related to the near extinction of light at the band center relative to the band shoulders. The second experiment examined the degree to which light transmitted through quartz sand samples would maintain any directional characteristics. Transmittance decreased monotonically as the illumination angle increase, but slowly at all wavelengths. This indicates that directional radiation transmitted through the sand layer becomes diffuse with a millimeters-thin sand layer. For the saturated samples, the influence of water on light transmittance in the VNIR (350-1300 nm) was the reverse of that in the SWIR (1330-2500 nm) wavelength region. In the VNIR, transmittance increased in the saturated sample relative to the dry sample, while transmittance decreased sharply after 1330 nm, with obvious spectral features characteristic of water absorption. Analysis of transmittance by quartz sand samples suggests that most of the directional variation due to the change in illumination angle can be attributed to surface reflective loss. The implication is that the directional reflection may be treated as a surface phenomenon, with the volume reflectance contributing a diffuse component. The third experiment considered directional spectral reflectance of soil samples under dry and saturated conditions. When the samples were dry, the directional reflectance changed obviously with the phase angle, showing a stronger backward reflectance, while the forward reflectance was generally lower. For saturated soil samples, the directional characteristics of spectral reflectance apparent with dry soil were substantially reduced. In particular, the strong backward scattering weakened.

▼ The presence of Arctic sea ice currently limits surface ship travel in the Arctic for most of the year. However, due to rising temperatures from global climate change, Arctic waters are becoming increasingly navigable for a greater percentage of the year. As interest in surface travel within the Arctic increases in the coming years, the safety of a ship operating in this context must be considered. Specifically, the possibility of ice accumulation on the topside of a ship is heightened due to environmental factors within the Arctic, including the presence of sleet, snow, freezing rain, and freezing spray. This additional mass on exposed topside surfaces, at the most extreme, could result in capsizing of a vessel. The present research develops a framework to monitor evolving mass properties for a ship in Arctic operation, in order to ensure safe travel through the Arctic. As with any real-world application, the data for this work are limited and noisy, and the system is complex. When the real-world data are limited, when the signals of interest are noisy, or when mechanistic models are unavailable, stochastic inference can enable informed decision making regarding the natural and built worlds. Thus, this work leverages stochastic inference in order to investigate the real-world problem of Arctic travel. First, the dissertation presents a proof-of-concept for applying this framework to identify a single mass parameter for the Research Vessel (R/V) Melville with no icing and in quiescent seas, both at model-scale and full-scale. Second, the framework is extended to consider multiple mass parameters of the R/V Melville while undergoing potential ice build-up configurations. The third component of the dissertation looks outwards to the sea, to gauge the near-field wave forcing acting on the ship. In particular, the present work reports on a validation experiment of an existing algorithm to determine scale and sea state from an uncalibrated camera. Taken together, the chapters prepare a foundation from which an ice monitoring system could be implemented. The chapters also provide insight to the specific challenges that exist for the full realization of the proposed framework. While the presence of ice is a focus of this work, the framework could easily be translated to a ship operating in within a context in which any mass property is evolving; those systems may require the monitoring of different mass parameters, but the underlying framework and approach proposed here would remain unchanged.

▼ Ground based water resources monitoring systems are often difficult to maintain consistently in developing countries. The decline in the number of stations, data quality and changes in the data holding policy has made water resources data less reliable for use in operational purposes. The objective of this dissertation is, therefore, to evaluate the utility of existing freely available remotely sensed images to monitor water resource systems. In this dissertation Moderate Resolution Imaging Spectroradiometer (MODIS) images were evaluated on the basis of their capability to (1) measure total suspended solid (TSS) and turbidity and generate historical TSS data, (2) estimate the water storage variation of Lake Tana and (3) monitor the state of biomass in the upper Blue Nile basin . The usability of historical TSS data in hydrologic modeling is also tested. Lake water samples were collected concurrent with the satellite overpass over the lake at the entry location of Gumera River, a major tributary to the lake. Reflectance in the red and near infrared (NIR) 250 m-pixel images taken on sampling days were correlated and validated using measured TSS and turbidity. The validated correlations were applied to the ten year image archive of MODIS to generate a 10-year TSS time series for the lake. In addition, MODIS images of the years 2002 - 2003, where the lake level variation was at its minimum, were used to generate the lake near-shore bathymetric model. The new near-shore bathymetric model reproduced water level measurements with a better accuracy than the existing bathymetric model of the lake. The usability of the TSS data was tested by initializing a hydrologic model for the Gumera watershed using the Soil and Water Assessment Tool (SWAT). The ten year TSS data generated were used to calibrate the model. The model was capable of predicting the monthly TSS variation. The potential of MODIS images in monitoring biomass recovery was also assessed at river basin scale. The enhanced vegetation index (EVI) - land surface temperature (LST) relation is used to map the trend in the disturbance of plantations put in place as conservation measures. In this dissertation the potential of satellite imagery as a data gap filling alternative to ground based monitoring systems in data scarce regions is tested.

▼ In this dissertation, internal waves (IWs) and turbulence in the stably stratified ocean are studied via a series of numerical simulations. First of all, internal wave beams that are representative of high-mode internal tide originated from the ocean topography and constituent element of turbulence-emitted IWs are studied via direct numerical simulations (DNS), with an emphasis on their reflection at the sea surface as modelled by a free-slip rigid lid. Nonlinear effects due to wave-wave interaction, such as mean flow and harmonics, are investigated; in particular, the amplitude of the wave-driven Eulerian mean flow is found to match the theoretical prediction of an inviscid weakly nonlinear theory. The IW beams can also degrade at late time of reflection due to parametric subharmonic instability. Subsequent particle tracking is performed based the DNS dataset, in an attempt to examine the mass transport driven by the reflecting IW beams. These fully nonlinear computations reveal a horizontal dispersion of ocean tracers with a dispersivity scaling with O(A4 ), where A is the steepness of the IW beam, while small-amplitude analysis accurate to O(A2 ) suggests an exact cancellation of Eulerian mean flow due to wave-wave interaction and the wave-driven Stokes drift. The second topic of the dissertation investigates the manifestation of submerged-turbulence-emitted IWs at the sea surface and the correlation between the IW characteristics to turbulent source of IW. The turbulent wake of a sphere of diameter D towed at speed U is investigated using three-dimensional implicit largeeddy simulations, in a linearly stratified Boussinesq fluid with buoyancy frequency N and kinematic viscosity [nu]. Six simulations are performed at Reynolds numbers Re ≡ U D/[nu] ∈ {5 x 103 , 105 } and Froude numbers Fr ≡ 2U/(N D) ∈ {4, 16, 64}, with the wave-emitting wake located at a fixed distance of 9D below the surface. As the wake evolves for up to O(300) units of buoyancy time scale 1/N , IW characteristics, such as horizontal wavelength [lamda]H and wave period T , are sampled at the sea surface via wavelet transforms of surface horizontal divergence signals. The statistics of amplitudes and orientations of IW-induced surface strains are also reported. The normalized mean observable wavelength [lamda]H /D at the sea surface decays in time as (N t)[-]1 , which is due to the waves' dispersion, the dominant process in the far-field, and is in agreement with a linear propagation model that is independent of the wake Re and Fr. This agreement suggests that, within the Re range considered, the most energetic waves impacting the surface originate from the early-time wake that is adjusting to buoyancy. Questions remain about the efficiency of late-time buoyancy driven stratified turbulence in radiating waves with ˆ considerable energy content. The most energetic wavelength [lamda]H , when normalized by D, is found to scale as Fr 1/3 and decrease with Re, which causes the arrival time (in N t units) of the strongest waves at the surface to scale… Advisors/Committee Members: Diamessis,Peter J.

▼ Motivated by the ubiquitous nature of turbulent surface features that are present on the surface of naturally occurring shallow flows, this dissertation leverages information contained within these signatures to remotely monitor bathymetry, bed shear stress and volumetric discharge. A series of Large-Scale Particle Image Velocimetry (LSPIV) and Acoustic Doppler Velocimetry (ADV) experiments are conducted in a wide-open channel for a variety of different bathymetric conditions. A methodology is developed that remotely and accurately determines volumetric flow rate from free surface imagery. This methodology takes advantage of the ubiquitous nature of counter-rotating vortices in wide-open channel flows, which have been demonstrated to scale with the flow and influence the pattern of velocity on the free surface. This approach to remote volumetric discharge monitoring is more efficient and cost-effective than current direct methods of determining volumetric flow rate. It reduces hazards to USGS personnel and yields the same or better accuracy relative to current methods. A second technique is developed that permits remote and large-scale assessment of bed shear stress. This is accomplished through correlation of dissipation measurements on the free surface with dissipation measurements in the upper portion of the water column. In open channel flow the distribution of dissipation in the water column follows a semi-theoretical relation developed by Nezu & Nakagawa (1993), which includes friction velocity. Hence, by understanding the correlation between free surface and near-surface values of dissipation, full depth profiles of dissipation can be approximated and the friction velocity, and subsequently bed shear stress, can be determined. The development of this technique has important implications for the prediction of sediment transport.

▼ Glaciers outside the icesheets currently supply roughly the same amount of water to sea level rise (SLR) as Antarctica and Greenland and will likely constitute a significant fraction of SLR through 2100. SLR is one of the biggest challenges facing humanity, and much uncertainty remains regarding the contribution of glacier mass loss to SLR. Here we examine glaciers in the Patagonia region of southern Chile/Argentina, the Russian High Arctic (RHA) and Alaska, which have all contributed disproportionately to SLR, a trend that is expected to continue through 2100. The RHA is projected to be among the largest contributors, with total mass loss exceeding Alaska for 2006-2100 despite its smaller ice volume. We focus on several icefields, including two that have received relatively little attention, the Cordillera Darwin Icefield (CDI, 69.6? W, 54.6? S, 2,600 km2 of glaciated area) in the Patagonia region of southern Chile, and the Novaya Zemlya Icefield (NovZ, 65? W, 76? N, 22,100 km2 of glaciated area) in the Russian High Arctic. We also examine the Juneau Icefield (JIF, 58.3? N to 59.7? N, 3,830 km2 ) and Stikine Icefield (56.75? N to 58.5? N, 5,800 km2 ) in southeast Alaska. We produce high-resolution maps of surface elevation change rates ( dh ) and dt velocities for these icefields. dh dt are calculated by applying a weighted lin- ear regression to horizontally- and vertically-aligned digital elevation models (DEMs), revealing thinning patterns for individual glacier basins and allowing us to estimate total mass loss for each icefield. To our knowledge, the work presented here includes the first published study to use the technique of DEM time series to study mass loss of entire icefields. Velocities are measured by pixel-tracking applied to satellite image pairs, helping constrain the dynamic component of mass loss and detect acceleration. We provide a brief overview of the impact of changing various pixel-tracking parameters on velocity measurements, demonstrating, for example, how the ability to adjust parameters helps maximize coverage compared to working with fixed parameter values. We find an average mass loss rate at the CDI of -3.9±1.5 Gt yr-1 between 2000 and 2011, the first produced for this icefield. Three marine-terminating glaciers that cover 12% of the icefield area account for 31% of mass loss. Velocity measurements at the largest of these, the rapidly retreating Marinelli Glacier, constrain the lower bound on the annual calving flux as approximately 82±41% of the average mass loss rate for the glacier. The disproportionate mass loss contribution of the three tidewater glaciers, coupled with the high calving flux and retreat at Marinelli Glacier, provide evidence that dynamic mass loss is an important component of thinning at the CDI. At NovZ, we extend estimates of mass loss back to 1952 and up to the present. We find that the recent average thinning rate of -0.41±0.10 m water equivalent yr-1 (m w.e. yr-1 , or elevation change at density of 1000 kg m-3 ) from 2012-2013/2014 is higher than the… Advisors/Committee Members: Pritchard, Matthew (chair), Pritchard, Matthew (chair), Lohman, Rowena B.

▼ A cross-sectionally averaged one-dimensional long wave model is developed. Three dimensional equations of motions for inviscid and incompressible fluid are first integrated over a channel cross section. To express the resulting one-dimensional equations in terms of the longitudinal component of the crosssectional averaged velocity and span-wise averaged free surface elevation, the characteristic lengths of the channel cross-section in the vertical and transverse directions are assumed to be smaller than the typical wavelength, resulting in the Boussinesq-type equations. The effects of viscous damping are also added in a heuristic manner. The new model is, therefore, adequate for describing weakly-nonlinear and weakly-dispersive waves along a channel of arbitrary non-uniform crosssection. More specifically, the new model has the following new capabilities: i) The arbitrary channel cross-section can be asymmetric with respect to the direction of wave propagation, ii) the channel cross-section can change significantly within a wavelength, iii) the effects of viscosity inside the bottom boundary layer can be considered, and iv) the three dimensional flow features in a crosssection can be recovered from the perturbation solutions. Analytical and numerical examples for uniform channels, channels where the cross-sectional geometry changes slowly and channels where the depth and width variation is appreciable within the wavelength scale are discussed to illustrate the scope of applicability of the present theory. By considering viscous boundary layer effects, the theory agrees well with experimental results for converging and diverging channels (Chang et al., 1979) and with experiments in a uniform channel with a sloping beach (Liu et al., 1979). The results for a solitary wave propagating in a channel in which the width variation is important within the wavelength are discussed. Curvature is introduced by means of orthogonal curvilinear coordinates following the channel. The resulting one-dimensional cross-sectional averaged equations contain new coefficients depending only on the geometry of the channel. To the level of approximation considered, these equations do not capture the free surface tilting due to curvature and show that the wave field is locally affected by the magnitude and sign of the curvature. The theory provides practical model equations for calculating long waves (e.g. tsunamis, tides or flood) propagation in fjord or river, which could have compelling applications in the field of hydraulics and coastal engineering. As an example, for long distance propagation of landslide tsunami in fjords, travel-times and maximum wave heights can be rapidly estimated from one-dimensional governing equations, making the present theory suitable for warning systems.

▼ It has been recognized that reliable, long-term and well distributed climate information is essential to inform any development policy that aims to address the consequences of climate variability and change on water resources. However, in developing countries planning of such activity is greatly hampered by the lack of a sufficiently dense network of weather stations measuring precipitation. The objective of this dissertation is, therefore, to evaluate the freely available high resolution satellite rainfall estimates in the Lake Tana Basin which has a relatively denser ground rainfall stations network. Rainfall estimates of Tropical Rainfall Measuring Mission (TRMM) 3B42 version 7, EUMETSAT's Meteorological Product Extraction Facility (MPEF), Multi-Sensor Precipitation Estimate-Geostationary (MPEG) and Climate Forecast System Reanalysis (CFSR) are considered. The satellite rainfall is validated by a direct comparison with the gauged rainfall data, and through hydrological modelling to capture the observed flow using a semi-distributed hydrological model Hydrologiska Byråns Vattenbalansavdelning (HBV) and Parameter Efficient Distributed (PED). The result of direct comparison indicated that, the MPEG and CFSR rainfall provided the most accurate rainfall estimates. On average, for 38 stations, 78 and 86 % of the observed rainfall variation is explained by MPEG and CFSR data, respectively, while TRMM explained only 17% of the variation. The hydrological modelling indicated that both the gauged and the CFSR precipitation estimates were able to reproduce the stream flow well for either of the models. The TRMM data was not be able to capture the observed flow through model calibration for both models. Bias corrected MPEG rainfall by the gauged monthly means performed as well as or better than the gauged rainfall data in capturing the observed flow through hydrologic model calibration. This dissertation has also identified potential irrigable areas by considering hydrological and landscape factors that determine lack of irrigation development in the Ethiopian highland. Potential land areas suitable for surface irrigation were determined by using a GIS based MultiCriteria Evaluation (MCE) technique by considering climate characteristics (rainfall and evaporation), land features (soil type, land use and slope), market access (town and road proximity) and proximity to a perennial river. The available water for surface irrigation was quantified by analysing historical river flow data during the dry season of the major rivers in the Lake Tana Basin. The result indicated that the main limitation for surface irrigation in the Ethiopian highlands is the availability of water and not land suitable for irrigation.

▼ While millions of dollars and billions of hours of food-for-work farm labor have been invested in soil and water conservation practices in the (sub) humid Ethiopian highlands, sediment concentrations in rivers are increasing because land degradation and associated soil erosion remain a persistent problem in the Ethiopian highlands despite the conservation efforts. The objective of this dissertation research was, therefore, to better understand soil degradation and measures that can be taken to ameliorate the hard pans that have formed in degraded soils. The research was carried out in the humid Ethiopian highlands where land degradation is severe. The detailed study areas were the 113-ha Anjeni and 95-ha Debre Mewi watersheds in the Ethiopian highlands. In both watersheds, 0-45 cm soil penetration resistance (SPR, n=180) and soil physical properties (particle size, organic matter, pH, base ions, cation exchange capacity, silica content, bulk density and moisture content) were determined at 15 cm depth increments for three land uses: cultivated, pasture, and forest. In addition, 32 experimental plots were constructed in the Anjeni watershed to investigate the effects of ripping and liming of soil hardpans on runoff and erosion. The results show that the mean SPR of agricultural fields was significantly greater (at p<0.05) than that of forest lands. Dense layers with above SPR a critical threshold of ≥ 2000 kPa were observed in the cultivated and pasture lands starting at a depth of 15-30 cm but did not occur in the undisturbed forest land. Compared with the original forest soils, agricultural fields were: lower in organic matter, CEC, and exchangeable base cations. They were also more acidic, had a higher bulk density and more fine particles (clay and silt), and contained less soluble silica. Measurements in the ripped and limed soil in the field experiments in the Anjeni watershed showed that ripping to depths up to 60 cm increased infiltration and decreased runoff. Liming alone, on the contrary, increased runoff likely due to surface sealing. Deep ripping was not effective in reducing sediment yields and there was a tendency for deeper ripping to increase sediment concentration especially in the beginning of the rain phase. Liming decreased sediment concentrations compared with the unlimed plots. Overall, the findings suggest that land degradation is a process where soil physical and chemical properties in agricultural lands deteriorate after deforestation, causing disintegration of soil aggregates resulting in greater sediment concentration in infiltration water that clog macro-pores, thereby disconnecting deep flow paths found in original forest soils. This in turn decreased baseflow and increased direct runoff. This process is common in the Ethiopian highlands. Advisors/Committee Members: Steenhuis, Tammo S.

▼ Selected spectral reflectance features of soils are examined with respect to their relationship to soil water content. Three soil samples selected to represent a range of particle size distribution, texture, and drying characteristics were monitored as the samples progressed from fully saturated to air dry. Spectral reflectance was collected over the wavelength range 350 nm to 2500 nm, a range in which four major water absorption bands exist: two in the visible/nearinfrared (VNIR) region centered at 970 nm and 1160 nm, and the other two in the shortwave infrared (SWIR) region centered at 1440 nm and 1930 nm. The water absorption bands were the focus of this work with the expectation that these features would be the most sensitive indicators of the surface water content. However, the two absorption features in VNIR region were not useful for all three soils, so the two absorption bands in SWIR region became the focus in this study, especially the more sensitive 1930 nm band. Plots of the changing absorption band depths in the SWIR region were similar in shape among three soil samples. Three to four approximately linear stages were observed over the whole drying process, however, the transitions between drying stages did not occur at consistent points in the drying process, making it difficult to build a direct relationship between the absorption features and volumetric water content that would be independent of the soil type. Although no general, soil-independent relationship could be found between an absorption feature and volumetric water content, there were characteristic changes in the band depth features that were coincident with evaporation stage transitions. Initially, the depth of the band centered at 1930 nm increased steadily and slowly with decreasing soil water content, reached a maximum, and then abruptly decreased marking a distinct change between the early and late, relatively steady drying rate stages. During the late stage, the magnitude of the band depth decreased sharply with only a small change in water content. The decrease was coincident with the water evaporation transition from stage-1 (constant, relatively fast evaporation rate) to stage2 (slower evaporation rate), a transition which is related to the exhaustion of pore water and the initial loss of adsorbed water. The two SWIR water absorption band depths did not decrease with decreasing soil water content monotonically, which is counterintuitive. In order to understand the process, a simple mathematical model was built which suggested that the pattern of change in the band depth was related to the near extinction of light at the band center relative to the band shoulders. This extinction can be related to a specific water optical path length. The maximum absorption band depth at 1930 nm (and the associated water optical path length) appears to coincide with a trace amount of water present in the pore spaces for all three soil samples, which is consistent with the transition in drying rates.
