Drought in the Colorado River Basin: Spatiotemporal Analysis using an Edge Detection Filter
A detailed history of drought variability in the Colorado River Basin for the last half millennium was obtained using tree ring-widths of precipitation sensitive trees as a proxy record of past climatic conditions. A one-dimensional edge detection filter was applied to standardized ring-width …

Effectiveness of Municipal Collaboration for Watershed Management in the Southern Colorado River Basin
… jurisdictions within them in the Southern Colorado River Basin, where water is scarce, from their stormwater Annual Reports, as well as from USGS, NOAA, and Census data, and used pooled ordinary least squares regression to analyze the relationship of municipal cooperation from a period of …

Water, Agriculture + settlement design in the arid lower Colorado River Basin : 3 new models
… and agrarian/urban settlement processes in the Colorado River Lower Basin focuses on a region in a pivotal situation: Central Arizona and its agricultural irrigation districts. Here, the three models are tested on a hypothetical site of one square mile and simultaneously investigated in an …

Analysis of Human Influence on Drought Conditions in the Upper Colorado River Basin (Texas)
… change, is rarely studied. Here, the upper Colorado River Basin (Texas) is studied to assess the human influence on drought conditions in a semi-arid basin. An observation-modeling framework is used to simulate naturalized runoff conditions which are compared to observed data in an …

Las Vegas in an Era of Limits: Urban Water Politics in the Colorado River Basin
… influence SNWA water policy. Reliance on the Colorado River required adherence to city, county, state, and interstate laws. During a four-year period of political consolidation, the SNWA absorbed local, county, and state level power, a combination that enabled it to negotiate political …

Understanding beliefs and preferences of irrigators towards the use and management of agricultural water in the Colorado River Basin
… from a survey of farmers and ranchers who use Colorado River water for agricultural purposes, including: the pressures they are experiencing on their water supplies, options for addressing pressures, their interest and involvement in water transfer arrangements, and their preferences for …

Land Material Geometry: Spline Construction with Invasive Species in a time of Water Crisis in the Colorado River Basin
… an invasive species in southwestern desert river systems that exacerbate strains on water availability, thus, removing the plant, yet maintaining its sequestered carbon as construction material. Active bending of this raw natural timber allows for a low tech means to approximate structural …

Modeling Dissolved Oxygen in Lake Powell using CE-QUAL-W2
<p>Water quality models in the Colorado River Basin have been developed for the basin, river, and individual reservoirs. They are used to support water quality programs within the basin. The models are periodically reviewed and updated to improve the accuracy of simulations. Improving the …

Interpreting site formation processes affecting re-emergent cultural sites within reservoirs: A case study of St. Thomas, Nevada
… Dam was constructed to impound the waters of the Colorado River to create Lake Mead reservoir in 1935; providing irrigation, hydroelectric power and flood control in the lower Colorado River basin.;This research identifies those processes governing and manipulating site formation and the stability …

Development and Optimization of Airborne FMCW Radars for High-Resolution Snow Depth Measurements
… for freshwater supply. In the United States, the Colorado River Basin (CRB) gets 75% of its water from snow melt; it constitutes the water supply of 40 million people in seven states, two countries, and 5.5 million irrigated acres of land. An ultra-wideband (UWB) radar enabling snowpack …

Hydrologic sensitivities of western U.S. rivers to climate change
… through hydrologic model experiments in the Colorado and Columbia River basins - two basins which can be considered end points of hydroclimatic variability in the West, and which also have diverse management concerns as existing reservoir storage in these systems varies strongly. The total …

A service-driven approach to assist water management during extreme events
… study of the Texas flooding events in the Lower Colorado River Basin in November 2014 and May 2015, which involved a sudden switch from drought to flooding. We have constructed two prediction models: a statistical model for flow prediction and a hybrid statistical and physics-based model that …

Sampling methodology tradeoffs: evaluating monitoring strategies for the endangered humpback chub (Gila cypha) in the Little Colorado River, Arizona
… humpback chub (HBC) Gila cypha within the Lower Colorado River Basin (LCRB) has focused on hoop-net sampling within their primary spawning ground, the Little Colorado River (LCR). However, questions remain unanswered regarding their spawning strategy. Thus, due to the likely presence of both …

Drinking Water Infrastructure Assessment with Teleconnection Signals, Satellite Data Fusion and Mining
… were included on a seasonal basis in the Upper Colorado River basin which provides 97% of the inflow into Lake Mead. Identification of teleconnection patterns at a local scale is challenging, largely due to the coexistence of non-stationary and non-linear signals embedded within the …

Non-cohesive bank migration in meandering rivers and bank accretion in weakly braided rivers
… the dissertation is the migration of meandering rivers whose banks consist wholly, or partly, of non-cohesive bed-material-sized alluvial deposits; such banks are known as composite banks when the near-surface layers consist of fine-grained deposits. The relevant forces and environmental …
