Numerical Prediction of the Turbulent Flow with a Free Surface for 3-Dimensional Situation
An efficient finite-difference method, the HH-SIMPLE, has been developed that is based on a new concept of hydraulic pressure with two additional equations concerning the water surface...
An Alternative for Open Channel Flow Monitoring and Documentation
A Water Quality Impact Analysis of a Hydropower Facility
A low-head hydropower generating facility has been proposed at an existing dam site on a river. The state environmental agency has required an environmental evaluation into the potential...
Murray?Commissioning Maxi Hydro with Mini Flow
The Murray Hydroelectric Project contains two of the largest pit turbines in the world. An existing dam constructed for navigation and flood control on the Arkansas River, Lock and Dam...
Hydro on Hold
Hydropower projects have become the target of a growing environmental movement overseas. The tradeoff between clean, renewable energy and the possible environmental impacts of the reservoirs...
Movable Dam?Gate Selection Procedure
Very few new dams are now being considered, particularly for waterpower and even more specifically for low head waterpower in the lower reaches of major rivers. The City of Harrisburg,...
Pit Turbine Technology for Low Head Hydro Projects
Manufacturers of hydro generating equipment have developed designs that are adaptable to existing dams and suitable for upgrading and redevelopment of existing hydro plants. The pit turbine...
Visual Estimates of Flume and Weir Operating Conditions
Laboratory studies were conducted on a rectangular broad-crested weir to determine the effects of entrance and exit conditions on the prediction of discharge and required energy loss....
Kankakee Dam Discharge Characteristics
The low-head dam on the Kankakee River has flashboards which are installed as the discharge decreases in early summer, to maintain the upstream pool level. In response to concern over...
Scour Downstream of the Straight Drop Spillway
Tests made to determine the effect of high tailwater and long duration flows on scour downstream of the straight drop spillway stilling basin are presented in this paper. Results are presented...
Discharge Characteristics of Rectangular Profiled Weirs
This paper contains the results of a detailed experimental program carried out to define the discharge characteristics of rectangular profiled weirs. The flow region where the discharge...
Modeling Side-Weir Diversions for Flood Control
Side-channel weirs can be used for diversion to reduce flood peaks. This study has developed a means for incorporating the effects of side weirs in HEC-1 and HEC-2 calculations through...
Modeling and Verification of the Clinch River Weir
Coastal Response to Weir Jetty Construction at Little River Inlet, North and South Carolina
Effects of Semi-Impoundment on Fish and Crustacean Nursery Use: Evaluation of a Solution
Semi-impoundment of the marsh is one of the primary 'solutions' currently recommended to combat coastal marsh erosion, and also to improve habitat for waterfowl,...
Long Crested Weirs
A method has been developed to integrate and evaluate the head relationship between canal weirs and turnouts. The objective is to minimize flow variations through the turnout and at the...
Low Head Dam Safety Studied with Hydraulic Models
Use of physical models to study the hydraulic jump or submerged roller action created as water overflows low head dams provides an opportunity to develop design criteria for various structure...
Modeling Materials for Protecting Earth Weirs
This paper reports laboratory experiments on various materials used to protect earth weirs. Dumped rock, gabion mattresses, and shaped blocks on a gravel layer were subjected to high velocity...
Modeling the Effect of Weirs on Reservoir Releases
A computer model was developed to examine the influence of weirs on the rise of water levels and increases in velocities from reservoir releases. The model allows for investigation of...
Controlled-Drainage Supplements Subirrigation in Humid Regions
A computer simulation was conducted using climate and soil conditions of the humid southern U. S. to demonstrate optional operating methods for dual controlled-subdrainage/subirrigation...
