Natural, Cultural, & Environmental Resource Values Influencing Colorado River Basin Management
The Colorado River Basin supplies water to the seven western states of Wyoming, Colorado, Utah, Arizona, New Mexico, Nevada, and California, and to Mexico. Originally the Colorado River...
Wetland Engineering, Design, and Construction: State-of-the-Science and Research Needs
Local, state, and federal agencies, special interest groups, and individual landowners are undertaking wetland construction projects at a feverish pace to mitigate past and anticipated...
An Isolated Wetland Used for Stormwater Treatment
A marsh used for stormwater management showed gradually increasing levels of pH, dissolved oxygen and conductivity in the flow path. The system was especially effective in removing suspended...
Innovative Wetlands in Urban Settings Using Dredged Material
As a result of its work in the waterways of the nation, the U. S. Army Corps of Engineers (USACE) has restored or constructed wetlands using dredged material in a number of urban/suburban...
Sacramento and Trinity River Systems: A Demonstration of River Temperature Management for the 90's
Drought in Northern California resulted in the potential that summer and early fall, 1992, Sacramento and Trinity River temperatures would exceed critical levels for sustaining salmon...
Development of Bioretention Practices for Stormwater Management
This paper introduces the concept of bioretention as an innovative stormwater quality management practice. Bioretention is a method to treat the first flush of runoff using a combination...
Design Considerations Associated with Bioretention Practices
This paper presents the design requirements of bioretention practices. Bioretention is a stormwater management practice using a combination of retention, native terrestrial vegetation...
Long-Term Performance of Wet Detention Ponds
Wet detention is a technology which has been successfully applied in recent years to improve stormwater runoff quality in urban areas. Since most systems have a short operational history,...
Biological Modeling in the Columbia Basin: An Organized Approach to Dealing with Uncertainty
Development of the Columbia River basin has had a profound impact on its natural resources, particularly species of Pacific Salmon. Passage of the Northwest Power Act of 1980 put in motion...
Managing Snake River Operations for Juvenile Salmon Migration
A simulation model of Snake River hydrology and water management institutions has been developed. The model was used to investigate management changes to enhance flow conditions for migrating...
Columbia River System Operations ? Water Quality Assessment
In mid-1990, the U.S. Army Corps of Engineers, U.S. Bureau of Reclamation, and Bonneville Power Administration embarked on a Columbia River system operation review. Ten technical work...
Hydro Models and Salmon Recovery in the Northwest
Hydro regulation models provide extensive support for analyzing the efficacy of salmon recovery plans in the Northwest. Power planners developed these computer programs to help plan and...
Snake River Salmon Recovery Plan Development
The process used by the Snake River Salmon Recovery Team to develop its recovery plan is described. Major conditions affecting fish survival are identified. The Team's approach to evaluate...
Columbia River Basin Fish and Wildlife Program Strategy for Salmon
Three species of Snake River salmon have been listed as threatened or endangered under the federal Endangered Species Act. In response, the Northwest Power Planning Council worked with...
Snake Reservoir Drawdown ? A Brief Progress Report
The Northwest Power Planning Council has directed the region to employ the use of 'Drawdown' as tool to help threatened and endangered salmon stocks in Snake and Columbia rivers unless...
Role of Economics in Endangered Species Act Activities Related to Snake River Salmon
The development of recovery actions for the species of Snake River Salmon listed under the Endangered Species Act (ESA) must consider a wide range of actions covering the different life-cycles...
Water Quality Impacts from Development of Port Ludlow, Washington
Port Ludlow Bay is a tidal estuary located adjacent to Admiralty Inlet in Puget Sound, Washington. A planned development has been under construction along the bay since 1976. A 0.64 mgd...
Multiobjective Models for Determining Fresh Water Inflows to Bays and Estuaries
This paper presents two formulations of multiobjective models for the estuary management problem that are based on goal programming procedures. The multiobjectives are selected to be minimum...
Impacts of Hydropower Operation on Water Supply from Lower Colorado River in Texas
The Lower Colorado River Authority (LCRA) of Texas is both a water and energy supplier to a large area of Central Texas. LCRA generates approximately 10 percent of its power from hydroelectric...
Optimal Utilization of a Multi-Reservoir Water Distribution System
A water supply distribution system planning model (DSPM) has been developed using a linear programming approach. Unlike the conventional formulation, the water demand requirements are...
