Estimation of Bed Material Transport Capacity
A procedure is presented which combines several computational components for the estimation of bed material transport capacity in alluvial channels. Bed load transport is estimated through...

Hydrodynamic Simulations in Sediment-Carried Contaminant Modeling for the Buffalo River, New York
Accurate prediction of hydrodynamics is of great importance to modeling contaminant transport and water quality in a river and to estimating potential exposure contamination levels in...

Upper Chehalis River Pollutant Capacity and Load Allocations
Dry season water quality was evaluated in the Upper Chehalis River in western Washington state, focusing on low dissolved oxygen (DO), and using the Total Maximum Daily Load (TMDL) process....

Challenges and Opportunities in Egypt's Integrated Water Resources Strategy
Egypt's Nile irrigation system is a very complicated, old operated, continuously expanding system. It may be also described as a highly productive irrigated agriculture system....

Game Model Approach to Multi-Purpose/Multi-Objective Water Resources Related Environmental Protection Project Planning and Management in Developing Nations: A Nigerian Example
The best has not been realised from water resources related environmental protection projects in Nigeria due to problems militating against such projects at the planning, management and...

Environmental Considerations for Water Resources Development in Haor Areas of Northeastern Bangladesh
A haor is a bowl shaped depression which are flooded every year during monsoon. It remains under water for seven months of the year. This paper gives an outline of the environmental considerations...

Environmental Improvement in Southern Africa
Cross-border environmental projects in southern Africa are identified and discussed. The complexity of coordinating multinational standards, combined with the region's extreme...

Analyzing Drought with a Simplified Climate Model
A simplified climate model with combined atmospheric-hydrologic processes has been developed at the University of California Davis for the study of physical processes related to drought....

Drought in California: When Does It Begin and When Does it End?
California recently endured a six-year period of drought. While the public, media and control agencies like simple definitions to classify water conditions, in a state as large and varied...

Watershed Management for a Limited Coastal Aquifer System
Developing a watershed strategy, which incorporates key issues of a particular watershed, may entail the coordination of several different agencies. Work performed by the USGS, local public...

Development of a Regional Atmospheric-Hydrologic Model for the Study of Climate Change in California
An integrated model of atmospheric and hydrologic processes at regional scale over California has been developed in order to translate the large scale atmospheric conditions of critical...

Mapping Groundwater Vulnerability to Nitrate and Pesticide Contamination in the Salinas Valley, Monterey County, California
This paper describes the approach and the associated investigation leading to the development of groundwater vulnerability maps for a critical water supply region in the Monterey County....

Drainage Recirculation Project for Water Quality
The State Water Resources Control Board and the federal Environmental Protection Agency have described water quality objectives for selenium in the San Joaquin River. In order to achieve...

Flow through Vertical Barrier Screens?Numerical Model
A simple one-dimensional numerical model based on the energy equation is developed to predict the normal flow distribution through barrier screens composed of several vertical segments...

Juvenile Fish Separator Design
Separation by size of downstream migrant juvenile salmonids at hydroelectric projects in the Columbia River basin is an integral part of transportation and bypass programs. However, separation...

White River Fish Screen Project Planning and Design
In 1983, Puget Sound Power and Light Company (Puget Power) submitted a license application to FERC for the overall White River Project. One of the elements of the project application was...

Comparison of Water Backwash and Brush Cleaning Systems for Vertical Panel Fish Screens
Vertical plate fish screens have been installed at a number of locations within the Pacific Northwest The vertical orientation of the screen panels requires screen cleaning systems designed...

Experimental Uncertainty and Measurement Errors in Hydraulic Engineering
The Task Committee on Experimental Uncertainty and Measurement Errors was formed to provide information and guidance on current practices used for describing and quantifying measurement...

Coastal Engineering Laboratory and Field Measurements: Some Uncertainties in Measurement
In this paper two examples of uncertainties which can occur in field measurements and measurements in coastal engineering models are examined. These examples are chosen to demonstrate...

Analysis of Exceptional Meteorological Conditions on July and August in Conakry
Conakry is a zone that receives more precipitation than other countries in West Africa. Sometimes the quantity is more than 4,000 mm per year. Strong rainfalls are observed between July...
