Field validation of a nearshore circulation model for alongshore-nonuniform flows

Creator:: Wilson, Gregory W.
Abstract:: We investigate, theoretically and experimentally, the problem of modeling depth-integrated (2DH) surf zone circulation on an alongshore-nonuniform natural beach, with waves approaching from an arbitrary angle. An approximate theoretical model is developed, which captures the important effect of advection in the alongshore dynamics, and shows that a nondimensional parameter Re[subscript]s...

Sediment Deposition Characteristics in Shallow Saturation Excess Overland Flow with Application to Bioswales and Construction of a Novel Bioswale Design for Improved Contaminant Removal from Stormwater

Creator:: Wells, Jacqueline R.
Abstract:: Over the last two decades, urban stormwater management has grown to include green infrastructure, such as bioswales. These systems were primarily designed to mitigate hydraulic peaking during rainstorms but were also found to remove particulate and dissolved contaminants. However, little is known about the fate of these particulate contaminants after...

Efficient Topobathymetric Mapping and 3D Spatial Analysis of Estuaries Using Multi-Platform, Multi-Temporal Data

Creator:: Lambert, Selina E.
Abstract:: Frequent 3D spatial mapping of estuaries is critical to understanding and modeling changes that can impact ecological health (e.g., water quality) and ecosystem services (e.g., aquaculture, nutrient cycling, and shoreline stabilization). However, obtaining accurate, repeat topobathymetric data for estuaries is a major challenge. Because shallow estuaries are typically not used...

Measuring sediment transport rates using tracer gravel and RFID technology

Creator:: Lewis, Logan L.
Abstract:: Rates of sediment transport were determined using tracer gravel and a RFID antenna array at Oak Creek (Oregon) to compare a new method with an existing transport relation created from data previously collected in the same study reach. Close to 3,000 tracers were deployed throughout the study reach and were...

A food web analysis of a Mojave Desert geothermal spring system and feeding ecology of Moapa dace (Moapa coriacea)

Creator:: StSaviour, Adam
Abstract:: Understanding food webs is fundamental in conserving endangered species and maintaining healthy ecosystem function, particularly in desert spring systems. We identified dominant energy sources in the Muddy River Warm Springs area, Clark County, NV using carbon and nitrogen natural abundance stable isotope analyses. We examined isotopic signatures of specific macroinvertebrate...

Characterization of CoGe Thin Films and Powders

Creator:: Pfau, Andrew James
Abstract:: Cobalt germanides have been widely studied as semiconductor contact materials, but recent theoretical studies suggest that they may also be excellent catalysts for methane steam reforming with stabilities and activities comparable to noble metal catalysts. In order to study the catalytic activity of cobalt germanides, it is critical to first...

2,4,6-trinitrotoluene detection using photoluminescence response of diatom biosilica functionalized with single-chain variable fragment

Creator:: Zhen, Le
Abstract:: A label-free, photoluminescence (PL) based biosensor for 2,4,6-trinitrotoluene (TNT) detection was developed by functionalizing diatom biosiilica with a TNT-specific single-chain variable fragment (scFv). The scFv loading was estimated to be 0.040±0.003 (μg scFv/μg biosilica). In saturated concentration, TNT binding to scFvbiosilica quenched about 13% of its PL. Dose response follows...

Device Fabrication and Characterization for Biological and Radiation Sensing

Creator:: John, Stebby Varghese
Abstract:: Amorphous indium gallium zinc oxide (IGZO) thin film transistors (TFT) has revolutionized the display industry enabling smaller pixel sizes and higher refreshing rates than traditional amorphous Si: H TFTs. These attributes of IGZO were leveraged to make a field-effect sensing (FES) platform capable of sensing various biomarkers. The sensitivity and...

Oxidation of Amorphous Metal Alloy Surfaces Studied Using Ambient Pressure X-Ray Photoelectron Spectroscopy

Creator:: Alzaga Elizondo, Pedro
Abstract:: Amorphous metal thin films (AMTFs) are of growing interest due to their unique mechanical properties and chemical stability. AMTFs have an advantage over polycrystalline metal films due to the lack of grain boundaries which gives AMTFs added durability and relatively smoother surfaces. For this reason, AMTFs have been investigated as...

Quantification of Ecological Change Using Repeat Photography and Ground Based Lidar

Creator:: Batchelor, Jonathan L.
Abstract:: Remote sensing techniques have long been useful in quantifying changes in ecosystems and the field of remote sensing is constantly evolving to better assess and describe changes, both spatially and temporally. In this thesis I explored the novel use of two remote sensing methods to quantify ecosystems; repeat photograph to...
