The making of a multiple purpose dam : engineering culture, the U.S. Bureau of Reclamation, and Grand Coulee Dam, 1917-1942
… the environment through the construction of new technologies and the roles of technical professionals in bringing about these changes. In the twentieth century, federal engineers, working with local Western boosters and their federal superiors, transformed the West's waterscape. Between …

Thermo-mechamical modelling of arch dams for performance assessment
… undertaking a successful performance analysis of concrete arch dams. Arch dams experience high temperature variations, which are generally assessed using finite element models. Deterioration of arch dams is caused principally by thermal effects, with 19% cases attributed to freezing and …

Algal Succession and Nutrient Dynamics in Elephant Butte Reservoir
… chosen for this study was CE-QUAL-W2 because of its proven ability to represent hydrodynamics and the ability to represent multiple algal groups. Elephant Butte has been subject to large algal blooms. This study examined the phosphorus loading into the reservoir to see if it could sustain the …

The Last Conservationist: Floyd Dominy and Federal Reclamation Policy in the American West
Historians of the American West have long identified the federal government's important role in shaping the region's physical and social landscapes, especially concerning water development. The Bureau of Reclamation, which built most of the West's major dams and water projects, traces its origins …

Analysis of riprap design methods using predictive equations for maximum and average velocities at the tips of transverse in-stream structures
… obstructions having one end along the bank of a channel and the other projecting into the channel center and offer protection of erodible banks by deflecting flow from the bank to the channel center. Redirection of the flow moves erosive forces away from the bank, which enhances bank …

Kytoon observations of the Lake Mead boundary layer
On July 14--16, 1997 nearly 60 hours of kytoon sampling of the boundary layer at Lake Mead was done through a cooperative effort among the U.S. Geological Survey, National Oceanic Atmospheric Administration, and U.S. Bureau of Reclamation. Micrometeorological data (MET) were analyzed to find …

A new optimization method for reservoir systems
… optimization methods. However, the transfer of optimization methods to general practice has proven to be challenging. This research introduces a new approach suitable for realistically large systems that (i) overcomes computational shortcomings of traditional management methods and (ii) can …

Development of a model for simulation of solute transport in a stream aquifer system
A model for simulation of solute transport in a stream-aquifer system is developed. The model is referred to as: Model for Stream-Aquifer Solute Transport or MSAST. The MSAST is developed by coupling four primary models: The groundwater flow model, MODFLOW-96, the coupled groundwater surface water …

Groundwater Banking in Imperial Irrigation District: Planning for Future Water Scarcity on the Colorado River
… to use 3.1 million acre-feet (MAF) per year of Colorado River Water (Regional Water Management Group 2013 and Imperial Irrigation District 2009). Of this water entitlement, IID uses 97 percent for agricultural production. In addition, IID supplies water to San Diego and Los Angeles urban …

From Cadillac to Chevy: Environmental Concern, Compromise and the Central Utah Project Completion Act
… water supplies in the arid West. The last of the large-scale federal reclamation projects to be completed is the Central Utah Project or CUP. The CUP has generated considerable controversy throughout its history. The projects opponents have criticized its expense in terms of both dollars …
