An Engineering Evaluation of Fine Sedimentation at the Mayport Naval Basin, Mayport, Florida
The Mayport Naval Basin is located near the mouth of the St Johns River in northeastern Florida, U.S.A. A total of 16.8 million cubic yards of fine sediment were dredged from the harbor...

Composite Liner, Leak Detection System, and Floating Cover for Nuclear Reactor Emergency Retention Basins
Existing reactor effluent basins are being retrofitted with composite liners, leak detection system and floating covers. Such basins have a 15-year life and remain empty until an accident...

Modeling Analysis of CSO Impacts in a Tidal Basin
Short duration intensive inflows of combined sewer overflows (CSO) to marine tidal basins create stratified water quality for limited periods of time. Accurate assessment of water quality...

C.t. Disinfection Practices in Open Chlorine Contact Basins
Susequent to an increased incidence of giadiasis in the coomunity in 1982 it became evident that Westpac had to improve its disinfection process and its ability to determine their effectiveness....

A Water Availability Index for Reservoir Management
This paper extends tha Water Availability Index concept to downstream reservoirs in the Apalachicola-Chattahochee-Flint (ACF) system. This extended index should be helpful in adjusting...

A Case for Modernizing the Funding and Repayment of Regional Water/Power Projects
Several regional water/power projects authorized by Congress remain unfunded and therefore uncompleted year after year. In this paper examples of such uncompleted projects are examined....

Cooperation and the Endangered Species Act
Passage of the Endangered Species Act (ESA) in 1973 set the stage for some of the nations most polemic environmental battles. One of these is in the Colorado River Basin which is home...

Feasibility of Adding Small Hydro to Federal Hydraulic Structures in the Upper Ohio River Basin
A national hydropower program exists in which non-Federal interests may develop power at Federal hydraulic structures which have that potential. This paper discusses associated considerations...

An Alternative Approach to the Maximum Flood Concept
This paper outlines an alternative to the current approach for determining the maximum flood of river basins. The condition of the maximum flood is derived from the convolution integral...

Validation Studies on Indexed Sequential Modeling for the Colorado River Basin
A method called indexed sequential modeling (ISM) has been developed by the Western Area Power Administration to estimate reliable levels of project dependable power capacity (PDC) and...

Columbia River System Operation Review
For many years hydroelectric power has been a surplus commodity in the Pacific Northwest. However, this picture has been changing rapidly in recent years. Increasing pressures for use...

New Techniques and Data Sources for PMP
Testing has been conducted on new methods and storm data sources for the past two years with the purpose of providing more tools to dam owners for the assessment of probable maximum precipitation...

Surface-Drained Level Basins for Rice Production
Surface-drained level-basin systems, consisting of a series of terraced level basins in which a portion of the applied water is drained from the inlet end of the basin, can be used to...

The Ala Wai Canal?From Wetlands to World-Famous Waikiki
The Ala Wai Canal, a man-made tidal estuary on the island of Oahu, Hawaii, is located about a half mile (0.8 km) landward of Waikiki beach and is two miles (3.2 km) long. As Hawaii's...

Erosion Potential of Pacific Basin Precipitation
Average annual erosivity (EI) values were developed using 20 years of hourly precipitation data from weather stations located on each of 10 Pacific Basin islands. Average annual erosivity...

Forecasting Irrigation Water Supply Using a Computer Model and Remotely Sensed Snow Cover
Improved streamflow forecasting in the Sevier River Basin is one objective of the Sevier River Water Management Study. Short-term forecasts are needed for optimum operations of irrigation...

Uncertainty in Climate Change and Drought
A series of projections of climate change were applied to a watershed model of the Delaware River basin to identify sources of uncertainty in predicting effects of climate change on drought...

Optimizing Regional Detention Basins for Price Expressway
Stormwater runoff from the drainage area contributing to the Price-Santan Freeway is captured in regional detention basins which require a series of pump stations for evacuation. With...

Preventing Stilling Basin Abrasion
A 1:10 scale physical hydraulic model of Taylor Draw Dam outlet works was used to develop modifications to prevent back flow intake of rock into the stilling basin. Much of the back flow...

Natural Salt Pollution in the Brazos River Basin
Water quality in several major river basins in the Southwestern United States is seriously degraded by natural salt contamination. The salt originates from geologic formations underlying...
