Analytical and Empirical Methods for Predicting Channel Shoaling
Many techniques have been used in the past to predict the effects of channel enlargement on channel shoaling. These range from rule-of-thumb predictions to elaborate physical model investigations....
Landslide-Generated Wave Studies
A serious safety of dams problem is associated with large masses of rock and debris plunging into lakes and causing damaging water waves. This concern prompted the Bureau of Reclamation...
Behavior of Sediment-Laden Plumes on Steep Slopes
The near field behavior of dense, sediment-laden flows on steep slopes was investigated as part of a study of mine tailings disposal. A literature review indicated that field and laboratory...
Bidirectional Seismic Response of Simple Structures
For design purposes it has been common to consider that seismic excitations act in one direction at a time. Analytical studies over the past decade have indicated that this may not be...
Influence of Artificial Island Side-Slopes on Ice Ride-Up and Pile-Up
An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms...
Iceberg Interactions with Offshore Structures
Various aspects include the component problems corresponding to iceberg drift in open water, iceberg drift in the vicinity of a large offshore structure, wave-induced motions of a berg,...
Comparison of Wave Overtopping Prediction to Measurements from Large-Scale Model Tests
A recent large-scale physical model study was sponsored by Arco Alaska, Inc. , to evaluate slope designs for an Arctic offshore oil drilling island. The drilling island will be located...
Comupter-Aided Real-Time Reservoir Operation Methods
Over the years many mathematical models have been developed with potential application to computer-aided real-time reservoir operations. Only a few of these models have been practically...
Micro-Computer Water Develoment Screening Models
A micro-computer screening model was developed to analyze the physical and economic efficiencies of a large number of alternative options associated with a given water development project....
The Water Resources Models of the Instream Flow Group
The Instream Flow Group of the US Fish and Wildlife Service has five analytical systems designed to assist in the development of instream flow criteria for water resources projects. Models...
A New Approach to Activated Sludge Plant Design
Activated sludge plants are designed on the basis of stationary tests at laboratory scale for constant organic loads and constant input flows. From these tests the kinetic parameters are...
New Orleans Flood Gates Hydraulic Model Study
A hydraulic model study was conducted to evaluate the forces exerted on selected floodgates by flowing water as the gates are closed after flooding has begun. The results of the study...
Simulating Flow in the Tidal Potomac River
A one-dimensional unsteady flow model has been applied to the tidal Potomac River, including its major tributaries and marginal embayments, between Washington, D. C. and Indian Head, Md....
Numerical Modeling of Fine Sediment Physical Processes
Fine sediment in channels, rivers, estuaries, and coastal waters undergo several physical processes including flocculation, floc disruption, deposition, bed consolidation, and resuspension....
Biological Evaluation of Angled Screen Test Facility
The paper presents comparisons of model and prototype measurements as a means for evaluating the ability of a physical model to reproduce a geometrically complex prototype thermal intake...
Automation of a River Model
The U. S. Army Engineer Waterways Experiment Station (WES) has used physical models to study sedimentation problems since 1931. With the recent advent of new technology, it was realized...
Unique Utilization of a Physical Model to Develop a Construction Sequence of a Major Cofferdam
Lock and Dam 26 Replacement is being constructed on the Mississippi River about 2 miles downstream of the existing Locks and Dam No. 26 at Alton, Illinois. This paper discusses the unique...
The U.S.G.S. Modular Ground-Water Flow Model: Designed to be Understood and Adapted
The paper discusses a carefully designed model program and its complementary complete description of all of the physical and mathematical concepts used in the model. The model program...
Development of a Practical Method Simulating Oil Spill Migration (OSPIM) in Soils
Many ground-water modeling studies can be performed on currently available microcomputers. The greatest problem associated with the proliferation of ground-water modeling software for...
Impact on Test by Various Multiaxis Excitation
The purpose of this paper is to provide input guidelines in evaluating various types of multiaxis excitation on fragility level testing of electronic devices. There are many variables...
