Some Considerations in Model and Field Data Selection for Circulation Studies of the James River Estuary
The major features of the circulation of the lower James River estuary are presented. The capabilities of numerical hydrodynamic models in reproducing these features are discussed, leading...

Modeling Residual Chlorine in the Potomac Estuary
This paper presents the development and application of a two-dimensional finite element hydrodynamic and water quality model, termed Neleus, to assess chlorinated discharges to the Potomac...

Data-Collection Program for Pamlico River Estuary Model Calibration and Validation
An investigation is being conducted to collect and interpret continuous records relating to the flow characteristics of the Pamlico River Estuary, North Carolina, and to calibrate and...

High-Country Hydro
The North Fork Stanislaus River Hydroelectric Development Project is a new 205 MW $267 million hydro plant in the Sierra Nevada Mountains. Completed in 1989, the project was the largest...

A Method for Estimating Peak Flows from Small Agricultural Watersheds
An attempt was made to develop a method for estimating peak runoff from agricultural watersheds by analyzing precipitation and runoff data, and incorporating the results into a procedure...

Climate Change and Resulting Hydrologic Response: Illinois River Basin
In the last 20 years, the northern half of the Illinois River basin has been experiencing a wetter and cooler climate. This climate change has significantly increased Illinois River flows...

Glacial Icemelt in the Wind River Range, Wyoming
The Wind River Range of Wyoming contains the greatest concentration of glaciers in the American Rocky Mountains with two of the larger glaciers being Dinwoody and Gannett Glaciers. This...

Environmental Compliance and River Maintenance on Santo Domingo Pueblo, New Mexico
River maintenance activities within the boundaries of the Santo Domingo Pueblo on the Rio Grande have departed from the traditional channelization philosophy and employed engineering methodologies...

Management Strategies for Baseflow Augmentation
Management strategies for baseflow augmentation fall into the following categories: (1) range management, (2) upland vegetation management, (3) riparian vegetation management, (4) upland...

Development and Implementation of the Wekiva River Basin Regulatory Program in Central Florida
The St. Johns River Water Management District developed a comprehensive surface water management program for the basin. Between 1987 and 1989 the District implemented basin specific design...

Effects of Mining, Grazing, and Roads on Sediment and Water Chemistry in Birch Creek, Nevada
Assessment of the cumulative effects of mining and other land uses on water quality of Birch Creek showed that mine dumps and roads increased fine sediment deposits in some reaches. Fines...

Stream Bank Stability Prediction for C6 Stream Type Reconstruction
A hydraulic model investigation will be conducted to evaluate the effects of root system characteristics of three meadow plant communities on simulated bank erosion. The test will determine...

Stream Standards for Toxics and Irrigated Agriculture Using New Mexico as a Case Study
New Mexico follows a policy of 'antidegradation' with respect to the existing quality of a stream, but its standards specifically exclude return flows from irrigated...

Delivering Appropriate Quantities of Water to the Farm
To study how well an irrigation district was able to meet farmer demand, water deliveries along two monitored lateral canals were compared to the orders and bills for these events. The...

The Colorado River Salinity Program?An Overall Perspective
Economic losses resulting from increases in salinity in the Colorado River system were estimated to be $311 million annually in 1986. As a result of protests by Mexico to the United States...

The USDA Colorado River Salinity Control Program
Approximately 37 percent of the salt contribution in the Colorado River can be attributed to irrigation activities in the river basin. The United States Department of Agriculture (USDA),...

Water Quality Criteria for Cyanide in the Similkameen River, British Columbia
The toxicological and environmental significance of the major cyanide compounds is discussed. Data from earlier bioassays studies of cyanide are summarised and the ranges of median lethal...

Water Quality of Jubba River in Somalia
Monitoring of water quality in the Jubba River in Somalia of East Africa, led to indications of a potential impact of toxic trace elements, salinity and biocides in restricting agricultural...

Environmental Aspects of Water Resources Development
Long-term management of resources requires a comprehensive anlysis of the effects that development and management of one resource may be expected to exert upon other resources. However,...

Annual Flow Variations in the Nile River System
The annual flow series of the Nile River System at some key gauging stations for the period 1912-1988 are presented and discussed. The relatively stable period, pre-1961, has helped establish...
