Development of a GIS for the U.S. Great Lakes Shoreline
The Computer Mapping Center of the Detroit District, U.S. Army Corps of Engineers (USACE) is developing a Geographic Information System (GIS) to contain physiographic, demographic, and...

Overfall Stress and Pressure Distributions
The magnitude and distribution of hydraulic shear stress and pressure on the boundary of a straight drop overfall are presented for multiple overfall heights and flow rates. Hydraulic...

Jet Injection Model Studies for the City of Los Angeles
The Hypersion Treatment Plant for the City of Los Angeles is currently undergoing an expansion project. A major component of this system is a sludge recycling system. And it is essential...

Southwest Pass Training Structure Alternatives
The U.S. Army Engineer Waterways Experiment Station system of computer programs, TABS-2, was utilized to evaluate various structural plans for increasing channel velocities and sediment...

Prediction of Siltation at a Point
This paper describes a zero-dimensional mathematical model which predicts siltation at a point on a cohesive sediment bed. The processes of erosion, deposition and consolidation are modelled...

A Numerical Analysis Approach to the Solution of Unsteady Flow in Open Channels
Several inherent characteristics of all current numerical simulations of the unsteady flow equations prevent total confidence in their use. Inconsistencies within the numerical procedures...

Infiltration Trenches for Urban Runoff Control
A two-dimensional finite element model has been developed to simulate the transient flow in a variably saturated porous medium for the study of infiltration trenches. Parameters such as...

UNET: A Model of Unsteady Flow Through a Full Network of Open Channels
UNET is a PC-based dynamic wave, unsteady flow model for the solution of the full network problem. The program applies a linearized implicit finite difference scheme to solve the full...

Design Procedures for Soil-Cement Grade-Control Structures
Grade-control structures are effective channel-stabilization measures that may be used singly or as a part of a stabilization plan involving such measures as bed and bank revetment. Grade-control...

Glacial Basin Flow for a Power Operation Model
A power operation model was developed and used to estimate the project energy generation and reservoir level fluctuations. In order to precisely simulate the daily project operation, daily...

Risk Assessment of System of Dams
The application of risk assessment to a series of dams on a river is presented here. A general discussion of the basic principles of risk assessment approach to dam engineering is given...

Debris Torrents in Nepal and Use of Reliability Engineering Concepts During Redesign of River Works
Debris torrents, generated by cloudbursts and by glacier lake outbursts, occur frequently in the Nepal Himalaya. A simple fault tree analysis is applied to the destruction of a diversion...

Evaluation of TR-55 on Coastal Watersheds
Results of a study of the applicability of TR-55 to coastal watersheds are presented. Historical data were used to evaluate curve number, time of concentration and unit hydrograph peak...

International Research on Mechanics of River Bank Erosion?A Summary Overview
A brief overview is presented of research regarding mechanisms of river bank erosion and treatments. In the research river planforms, water stages, currents, waves, ice sediments, bed...

The Tides Effects on the Dam Break Flood Wave
The accuracy of water level predictions downstream of the dam is dependent upon the breach evaluation, the correct estimation of the roughness coefficients and when the flood wave reaches...

Determining Hydro Project Dependable Capacity
Traditional techniques for estimating a hydro project's dependable capacity are of limited value when evaluating a hydro project in a thermal-based power system. For such...

Joint Economic Evaluation of Pumped Storage in Colorado
This paper summarizes a joint planning study completed in December 1988 on the economic potential of pumped-storage development. The study was unusual in water development investigations...

An Investigation of a Pumped Storage Hydropower System
In order to provide a realistic basis of determining the viability of a wind-powered hydroelectric system at a potential site, an evaluation technique has been developed. Basically, this...

Some Pertinent Considerations in Dam and Reservoir Design
Two important considerations in designing and constructing a multipurpose earthdam and reservoir are to minimize losses in the event of dam failure because of overtopping, and to conserve...

Thermally Developed Blade Stresses and Cavitation Damage
Cavitation damage to the turbine runner blades, to the draft tube liner, and to the runner hub requires extensive welding repair. The traditional repair method is to gouge out the damaged...
