Issues in Balancing Environmental Costs and Benefits in Water Resources Planning
Water projects differ in their physical and economic characteristics and their environmental impacts. Many environmental impacts are addressed through project design and these associated...
Performance of Prototype Aerating Weirs Downstream From TVA Hydropower Dams
TVA has constructed aerating weirs below certain of its hydropower dams to (1) increase tailwater dissolved oxygen (DO) content during generation, and (2) improve minimum flows between...
Is There a Future for Desalting in Meeting California's Water Needs?
This paper addresses the potential role of desalting reclaimed, brackish, and sea waters for use in meeting California's water needs. Brief descriptions of sources and costs are included....
Coping with Agricultural Shortages
Coping with agricultural shortages occupies most of the time and energy of the Kern County Water Agency (Agency). The Agency's participation in the State Water Project (SWP) originated...
Compacted Spillway
The compacted spillway (CSW) refers to a spillway accompanied by jets located on its face to dissipate the excess energy. The (CSW) has a standard ogee profile with three jets located...
Refined Modelling of Water Quality Constituents in a Semi-Enclosed Coastal Wetland Basin
Details are given of the refinements to a numerical model to improve the representation of the advective transport of water quality constituents. The higher order accurate scheme adopted...
Modeling Saltwater Intrusion Control Measures in the West Coast Basin
In the 1960's and 1970's the West Coast Basin Barrier was constructed to protect tha major coastal groundwater basin from further salt water intrusion, which had been occurring as a result...
Analysis of Cabinet Gorge Dam
After a 1987 inspection of the Cabinet Gorge Dam, Part 12 consultants contracted by Washington Water Power (a private utility based in Spokane, Washington) made several recommendations...
Hurricane Andrew in South Florida: Preparing a Water Management System for Disaster
This paper analyzes Hurricane Andrew from its beginning as a tropical storm to the powerful force that it later became. The careful monitoring that took place throughout its transformation...
Hurricane Andrew in South Florida: Steps to Recovery and Lessons Learned
This is the second part of a two-part paper which analyzes the development and impact of Hurricane Andrew in South Florida. The paper specifically deals with the experiences of the South...
Wetland Restoration in the Dutch Dune Area
Interference by man has affected the natural Dutch dune area seriously. The harmful effects of drinking water supply activities include low groundwater tables in the valleys, unnatural...
Modeling the Operation of a Water Quality Reservoir and its Effect on the Sacramento-San Joaquin Delta
The methodology used to model the operation of a 100,000 acre-feet (123 million cubic meter) water quality reservoir in Contra Costa County, California is described. Planning studies integrated...
Simulating THM Precursors Transport with DWRDSM
A study was conducted by the California Department of Water Resources (DWR) to demonstrate the ability of its Delta Simulation Model (DWRDSM) to simulate fate and movement of inorganic...
A Study of Lateral Bed Slopes Developed at Bend
A study was conducted to compare seven actual cross section profiles of Philip Bayou Realignment with the lateral bed slopes estimated from the model derived by Ikeda titled `Sediment...
Nonuniform Transient Sediment Transport Modeling
A numerical model based on Lai's (1991) multimode scheme for fully coupled simulation of water and sediment movement in mobile-bed alluvial channels with nonuniform bed materials has been...
Stratification Models Sensitivity to Solar Radiation Data
A one-dimensional water quality model (WESTEX model) for simulation of thermal stratification is used to test the performance of such models related to hydrometeorological input data....
