Laboratory Study of Mud Flows
In the study reported depth profiles and tip velocities were measured for a series of unsteady mud flows generated in a laboratory flume using a dam break scenario. Observation of a wide...
Rehabilitation Measures?Wanaque Reservoir System
The rehabilitation of Pompton Lake Dam and the dams of the Wanaque Reservoir System has provided the North Jersey District Water Supply Commission with a safe, dependable source of water...
Consolidation of Slurried Soils
This paper describes the use of large strain consolidation theory and centrifugal modelling to study the consolidation behavior of slurries. Laboratory testing of the slurry is needed...
An Investigation of the Alcatraz Disposal Site
The Alcatraz dredged material disposal site in San Francisco Bay is a dispersive site that is not intended to accumulate disposed sediment. However, the recent discovery of shoaling at...
Hydraulic Design of Pamo Dam Spillway
The design of the emergency spillway for the San Diego County Water Authority's (SDCWA) proposed Pamo Dam is discussed. Pamo Dam is a 264-foot (80. 5 meter) high roller compacted...
GLVHT Model Verification using Field Data
The Generalized, Longitudinal-Vertical Hydrodynamic and Transport model (GLVHT) as developed for the U. S. Army Corps of Engineers Waterways Experiment Station and described in Buchak...
Scour Downstream of High Level Emergency Spillways
The Corps of Engineers has numerous high level emergency spillways (HLES) including some that have the potential for excessive scour downstream during certain flow events. 'Excessive...
Development of Scour Channel After Spillway Failure
In November 1985 parts of the spillway which controlled the water level in Lake Charleston failed during a moderate flood event. The spillway failure resulted in formation of a large 'sinkhole'...
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...
Evaluation of Sand as a Modeling Material Using Vellinga's Guidance
An experimental series of flume tests were conducted using three sizes of sand as modeling sediment in order to evaluate the effect of sediment grain size and the range of validity of...
Improved Robustness of the NWS DAMBRK Algorithm
The combination dam breach and flood routing numerical model called DAMBRK has been developed by the National Weather Service (NWS) for forecasting river flooding events (Fread, 1984)....
Evaluting the General Well Function
The closest thing to a mathematical function that maps well discharge to drawdown has been Jacob's equation, caled the step-drawdown equation. However, this equation assumes the drawdown...
Hydraulic Model to Improve Debris-Handling Capability of Waterford Unit 3 Intake Canal
A 1:30 scale model was used to test the effectiveness of various modifications to the Waterford Unit No. 3 intake canal. The objective of the study was to assist in the development of...
A Large-Scale Groundwater Transport and Dispersion Test: The First 1000 Days
TVA is conducting a large-scale field experiment to quantify the groundwater transport and dispersion of leachates from solid disposal facilities. This project is an integral part of the...
Automation of Border and Basin Irrigation
Various methods and types of control equipment for automating border and basin irrigation are described. Mechanical gates include dual function turnout gates that both open and close and...
Field Evaluation of an Advance Rate Feedback Irrigation System
An experimental advance rate feedback system is described for furrow irrigation based upon a simple volume balance model in which surface storage during the irrigation event is neglected....
Selenium: It's Not Just in California
The U. S. Department of the Interior has embarked on a series of reconnaissance level investigations throughout the western states to identify and assess potential irrigation-induced water...
Laboratory and Field Determined Seepage (
In order to obtain quick and reliable estimates of seepage, an attempt was made to establish a relationship between one or more of the properties of concrete canal lining and seepage....
Physical Model Verification of a Coastal Discharge
A 1:75 scale physical model of a thermal discharge into a rocky, semi-enclosed bay was verified against extensive field data. The model accurately reproduced the prototype temperature...
Redundancy Evaluation of Existing Bridges
The redundancy of an existing bridge can only be correctly assessed by considering the full superstructure as a single entity. Any formulation based on the analysis of bridge components...
