Consideration of Sedimentation on Hydropower Projects
Experience gained by analysis of a number of hydropower projects throughout the world leads to the conclusion that it is necessary to consider sediment related aspects in the design and...

Examples of Risk Assessment in Dam Safety Decision Making
Three examples of risk-based dam safety evaluations performed for dam users or operators are summarized. These studies were conducted by major U.S. engineering firms and involved experienced...

Rehabilitation of the Dams at the Crescent and Vischer Ferry Hydroelectric Projects
This paper reviews the dam rehabilitation design and construction techniques used at the New York Power Authority's Crescent and Vischer Ferry Dams. The following are the...

Civil Design of the Sidney A. Murray Jr. Hydroelectric Station
This paper addresses the general civil design of the Sidney A Murry Jr Hydroelectric Station with special emphasis on the design requirements of the project's unconventional...

Evaluating History?The Edison Sault Powerhouse
The hydroelectric facility owned by the Edison Sault Electric Company at Sault Ste Marie, Michigan was an engineering marvel when it was designed and constructed. This paper explores the...

Pressure-Time Method Using Modern Practices
Over the past twenty years, Hydro-Quebec has modernized the pressure-time method of flow measurement, a method which is generally economical but sometimes difficult to apply. Starting...

UCD Drag Plate Lysimeter?Momentum and Mass Transfers
The second large (6.1 m dia., 0.97 m deep) lysimeter built at the University of California, Davis (UCD) was largely the brainchild of Dr. F.A. Brooks, the initial Project leader of a U.S....

Transpiration by Douglas Fir Using Lysimeters
During the spring of 1971 a 28 m Douglas fir tree was installed in a weighing lysimeter. Some details of construction are presented. The weighing mechanism consisted of eleven lengths...

Estimation of Loading via Fingered Flow
Results of experimental investigations of fingered preferential flow are combined into a concise, conservative engineering methodology for predicting pollutant transport through fingered...

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...

SRFR?A Model of Surface Irrigation?Version 20
The computer program, SRFR, comprises a mathematical model of flow in furrows, basins, and borders. It is designed for systematic, repeated application in the solution of design and management...

Impact of Grid Orientation on Groundwater Contaminant Transport Modeling Using the U.S.G.S. MOC Model
The U.S.G.S. method of characteristics (MOC) model was enhanced to include the input of measured contaminant concentrations, the calculation of computed and measured contaminant plume...

Pitfalls Associated with the Assumption of a Constant Partition Coefficient in Modeling Sorbing Solute Transport Through the Subsurface
This paper presents several case studies where the estimation of the adsorption coefficient, Kd, by means of the Koc-foc...

Modeling of Reactive Chemical Transport of Leachates from a Utility Fly-Ash Disposal Site
Fly ash from fossil-fuel power plants is commonly slurried and pumped to disposal sites. The utility industry is interested in finding out whether any hazardous constituents might leach...

2-D Groundwater Transport of Reactive Solutes with Competitive Adsorption
This paper presents a 2-D model, with applications, for the groundwater transport with competitive adsorption of a metal, a ligand and a complex. The model, called METLI, computes advection-dominated...
