Calibration of a Movable Bed River Model
This paper discusses the calibration procedures used for a model study of three miles (5km) of the Arkansas River. A hydro-power station will be added to an existing Corps of Engineers...
Convective Sedimentation from a Stable Turbid Layer
A set of experiments was conducted to test T Green's criterion for the existence of double-diffusive convective motions at an originally sharp, horizontal interface separating...
Intrusion of Turbid Water into a Two-Layer Stratified Environment
The horizontal intrusion of a turbid water with some intermediate density spreading on the interface of a two-layered homogeneous body of water is investigated. The study is directed towards...

Electricity From Air
After a decade of research and dozens of feasibility studies at sites around the country, the first Compressed Air Energy Storage (CAES) plant in the U.S. is under construction at McIntosh,...
Power Without Acid
Anticipating tighter acid rain controls, DOE is developing duct injection units that can be attached to existing powerplants. In a typical duct injection system, lime is sprayed into existing...
Top Projects for 1989
Transportation-related projects, most notably bridges, dominate the 1989 OCEA projects, but each of the 11 improved the quality of life of people in the community without harming the environment....
Scour Protection at the Straight Drop Spillway
Tests were conducted to determine the scour and the effect of tailwater on scour downstream of the straight drop spillway stilling basin. Preliminary results are presented on performance...
Routing a Cold Water Release Through TVA Reservoirs to Control Intake Temperatures at a Power Plant
A volume of cold water was routed some 160 miles through the TVA reservoir system to keep a nuclear plant intake temperature within safety limits. Mathematical modeling of the operation...
Hydraulic Transient Analysis of High-Head Hydropower Project
An iterative computer simulation procedure called LIQT (Liquid Transient), which performs simulations of hydraulic transients in closed conduit hydro-power systems, is used to estimate...
Convergence Experiments with a Hydrodynamic Model of Port Royal Sound, South Carolina
A two-demensional, depth-averaged, finite-difference, flow/transport model, SIM2D, is being used to simulate tidal circulation and transport in the Port Royal Sound, South Carolina, estuarine...
The Colorado River Simulation System
The Colorado River Simulation System (CRSS) is a comprehensive computer tool designed to assist water resource managers in long-range planning and management of the Colorado River Basin....
Design and Operation of Guard Gates
Guard gates for hydroelectric intakes and low-level outlets are normally intended for operation only under balanced heads. In the case of failure of regulating gates, the guard gate may...
The Estimation of Extreme Floods in Brazil
In Brazil, the design flood of a large dam is calculated using either the Probable Maximum Flood criteria or the 10,000-year Flood. Recently a Guidebook has been written to help Brazilian...
Climate Change and U.S. Water Resources: Results from a Study by the American Association for Advancement of Science
The time horizon of the changes that might occur is similar to the time required for planning, approval, funding, construction and economic life of such major water facilities as dams,...
Technical Considerations in Numerical Modeling of Pressure Reducing Valves in Water Distribution Systems
In large water distribution networks, pressure reducing valves (PRVs) are common water appurtenances. However, there are difficulties in representing them when using the Hazen-Williams...
Water Distribution System Design Considering Component Failure During Static Conditions
A continuous hydraulic availability relationship is presented which more realistically models minimum pressure requirements for water distribution systems. This relationship is used in...
Redundancy and Reliability of Water Distribution Networks: An Entropy Based Approach
Based on the concepts of entropy and graph theory, a functional form is developed as a quantitative measure for redundancy in water distribution networks. This function was obtained by...
Optimal Reliability Based Design for Water Distribution Systems
The methodology presented in this paper explicitly includes availability measures that incorporate both mechanical and hydraulic unavailability of system components for a dynamic system....
Optimal Interpolation of Bathymetry in the Thyrrehnian Sea
The bathymetry of the Tyrrhenian Sea in the area facing the electro-nuclear plant being built at Montalto di Castro, Italy, is reconstructed with the aid of the constrained kriging making...
