Watershed Runoff Forecasting Technique
Based on historical records of up to 57 years, a computer model was developed to establish the precipitation - runoff relationship for four reservoir systems in the Northeast portion of...

A Measure of Reservoir Efficiency
The notion of reservoir efficiency is defined for a water supply reservoir operated according to the standard policy, that is, one where the release is constant whenever physically possible....

Mathematical Modeling of Delta Deposits and Retrogressive Erosion in Reservoirs
A hybrid computer model which simulates mainly delta deposition and retrogressive erosion in reservoirs is described. Basic equations that govern the flow and bed changes used in the model...

Stochastic Streamflow Sequences for Reservoir Operation and Design
A stochastic streamflow model is adapted for risk methodology in the operation and design of reservoirs. The model is based upon the representation of the flood series as a Poisson counting...

U.S. Army Corps of Engineers Sedimentation Engineer Manual A. Overview
Until the 1970's, sediment analyses within the Corps of Engineers were mostly confined to estimates of the reservoir sediment storage needed, for the life of the project....

U.S. Army Corps of Engineers Sedimentation Engineering Manual D. Reservoir Sedimentation
This paper discusses Chapter 5, Reservoir Sedimentation, of the U.S. Army Corps of Engineers' Engineering Manual (EM) on Sedimentation Engineering, EM 1110-2-4000. The chapter...

Potential Effects of Global Climatic Change on the Tennessee Valley Authority Reservoir System
Rising concentrations of carbon dioxide (CO2) and other 'greenhouse' gases are likely to increase global temperatures and...

Sedimentation and Water Quality in TVA's Ocoee Reservoirs
This paper reviews and summarizes sedimentation and water quality characteristics of the Tennessee Valley Authority's (TVA) three Ocoee Reservoirs located in Polk County in...

Sediment Survey of Lake Powell
The 1986 Lake Powell Sediment Survey documented the present storage-elevation relationship and loss of storage from sediment accumulation since the reservoir began filling. From the calculated...

Martins Fork Reservoir Sedimentation Study
The Martins Fork Reservoir is located on Martins Fork of the Cumberland River in Harlan County, Kentucky. The lake was impounded in December, 1978. Since closure, the lake has experienced...

Utilization of Ground Penetrating Radar to Conduct Sediment Surveys of Frozen Reservoirs
The ground penetrating radar (GPR) system consisted of a control unit, antenna, recorder, a power supply on a sled towed by a snowmobile. A 120 Mhz antenna was utilized and gave excellent...

Sediment Flushing Experiences at Cherry Creek Dam
An overview of the U.S. Army Corps of Engineers, Omaha District's experiences in sediment flushing operations at Cherry Creek Reservoir near Denver, Colorado is presented....

Application of Reservoir Sedimentation Data to Problems of Environmental Management
Application of sediment delivery ratios and sediment routing procedures to sediment measurements provide an alternative approach to the prediction of localized average annual erosion rates....

Reservoir Sediment Sluicing?Laboratory Study
Experiments are being conducted in a 12.2 meter long, 0.38 meter high, 15 centimeter wide flume to examine the behavior of reservoir sediment deposits in response to sluicing. Crushed...

Water Supply Yields Power
During an overall renovation of the water supply system in Pittsfield, Mass. it was decided to bring water from three of the town's four reservoirs to a single treatment plant...

Water-Quality Ponds ? Are They the Answer?
Water-quality 'wet' ponds have been proposed to treat storm water for the removal of phosphorous in streams tributary to Cherry Creek Reservoir, a major recreational...

Optimizing Limited Water Resources Through Conjunctive Use
The City of Santa Barbara is faced with potential water supply deficiency caused by decreasing supplies and a mild increase in demand. This paper discusses some of the results of a study...

Conversion of a Reservoir Into a Landfill Site
The Writer is acting as a geotechnical consultant during the conversion of a disused water reservoir into a landfill site for domestic and industrial refuse. The site developer had no...

Simultaneous Releases from a Stratified Reservoir
The concept of simultaneously, selectively withdrawing water from multiple levels in a thermally, and therefore density, stratified reservoir is presented and its usefulness discussed....

Modeled Effects of Hydraulic Mixing Devices on Reservoir Water Quality
A two-dimensional reservoir water quality model was used to evaluate effects of hydraulic mixing devices on release and water quality. Seasonal simulations of Douglas Reservoir water quality...
