Model Study of New Madrid Pumping Station
The proposed pumping station on the New Madrid Floodway consisted of a draft tube type sump design (referred to as a formed suction inlet) to eliminate swirl and provide a more uniform...
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...
A Rational Approach to Selecting an Optimal Design Storm for Flood Control
A rational methodology is presented herein for determining the optimal design storm frequency when planning for flood protection in new urban areas. The technique was developed from an...
Siting the New Boston Outfall: Near-Field Considerations
This paper describes a procedure applied in near-field considerations for siting the new outfall to serve the Massachusetts Water Resources Authority's (MWRA) proposed regional...
Flow Characteristics in an Irregular Spillway Model
A physical model of the spillway for a proposed water supply reservoir near Meridian, Texas, was constructed to determine the optimum spillway design which would maintain an acceptable...
Physical Model Study of New York State Dam
The New York State Dam is located on the Mohawk River near its confluence with the Hudson River. Downstream from the dam, the river flow is divided into six channels as the water passes...
Optimization of Power Production Based on Efficiency Data
Computer programs dealing with different parts of the optimization process are in operation in Norway today, and they include: the hydrological part from weather forecast to reservoir...
Upgrading Open-Wheel Pit Hydro Plants with Modern Submersible Hydroturbines
This paper presents a new approach in rehabilitating open-wheel hydrosites by using modern, standard submersible hydroturbines, open flume type cylinder gates, and high efficiency draft...
Predicted and Observed Axial Behavior of Piles
Results of a Pile Prediction Symposium
This publication presents the results of a pile capacity event that was held at the Lakefill site on the Evanston Campus of Northwestern University in conjunction with the 1989 Foundation...
Project Control Via Acoustical Sensing
This paper describes ongoing research into automating the process of collecting project control information using acoustical sensing devices. The paper describes how frequency spectra...
The Simulation of Variable Release Temperatures from the Rock Creek-Cresta Project Using the USFWS Instream Temperature Model
Pacific Gas and Electric Company (PGandE) operates the Rock Creek-Cresta Project on the North Fork Feather River (NFFR) for hydroelectric generation under authority of Federal Energy Regulatory...
Computerized Operation Models of Oroville Reservoir
Two monthly computer operational models, OROTHM1 and OROTHM2, were developed to provide more detailed operation and maintenance studies for the Oroville facilities. Currently another computer...
Hydrologic Design Methodologies for Small-Scale Hydro at Ungauged Sites
IMP is a microcomputer package for evaluating small-scale hydroelectric power sites in British Columbia. With IMP it should be possible for an experienced hydroelectric engineer to make...
The Impact of Inlet Flow Characteristics on Low Head Hydro Projects
This paper discusses the intake civil designs, addressing head loss and flow distribution into the turbine intake. The impact of poor flow quality on head losses, turbine performance,...
Tracer Dilution Flow Measurement Application to Short Penstock Length
Absolute performance evaluation of hydro-turbines requires the determination of flowrates. Flow measurement is probably the most difficult aspect of determining a unit's efficiency....
Programmable mMicroprocessors in Local Control of Hydro Power Plants
The main purpose of the control equipment is to provide the generator with means for operation of the power station equipment. There is a need for status information on the generating...
Probabilistic Prediction of Pile Group Capacity
A reliability analysis of a group of free standing piles in clay is carried out using Monte Carlo simulation. The pile material strength, soil capacity, and the load on the pile group...
Prediction of Concrete Creep and Shrinkage by Sampling on the Basis of Correlated Random Material Parameters
There are many random parameters which influence creep and shrinkage of concrete. In all of the previous probabilistic studies the parameters are assumed to be mutually independent random...
Effects of Random Material Properties and Loads
The variability of slab deflections is estimated from analytical expressions accounting for random variations of spatially distributed loads and material properties (stiffness parameters)....
A Tower-Like Structure with Distributed Stiffness, Mass and Plastic Zones Under Random Earthquake Loading
Random vibrations of an elastoplastic structure are treated by taking into account the finite spread of plastic zones as well as the effects of distributed mass and stiffness. Solution...
