Pressure and Stress Distributions Due to a Submerged Impinging Jet
This investigation examines the pressure and shear stress distribution at a smooth planar boundary in the impingement region of a submerged vertical jet in water. The mean pressure and...
The Effect of Aeration on Scour
A vertical water jet was used to study the effects of entrained air, tailwater depth, size of bed material, jet diameter, and jet velocity on scour. Small amounts of entrained air were...
Evaluation of the Potential for Release of Residual Coal Tar by Flood Scour at a Superfund Site
To address the potential for release of residual coal tar by flood scour, stream cross-sections, stream discharge and sediment grain size data were collected during the Remedial Investigation...
A Generalized Diffusion Wave Flood Routing Model
A generalized diffusion wave model for flood routing is presented. The model can incorporate detailed data on natural cross sections and river bed geometry. An accurate numerical method...
A Multimode Scheme of Characteristic Method for Open Channel Flows
This paper deals with the stability and accuracy of a multimode scheme, based on the method of characteristics, for unsteady one-dimensional open-channels flows. This scheme combines three...
Hermite-Galerkin Model for Dam-Break Floods
A model based on the finite element method using cubic Hermite basis functions and Galerkin weighting was formulated to solve the partial differential equations that govern unsteady one-dimensional...
Diffusion Wave Overland Flow Module
This paper documents the diffusion-wave overland flow module contained in the FORTRAN-callable routine OVERLAND. Subjects covered include the theoretical background, model formulation,...
An Expert Advisor for Selective Withdrawal Operations
A rule-based computational advisor that aids in the selection of selective withdrawal operations for project release temperature maintenance is discussed. This advisor couples a one-dimensional...
Maintenance Scheduling for Water Resource Systems: An Application to Advance Maintenance Dredging
A number of investigations have been performed in the recent years to analyze the effect of advance maintenance and to see if it is justifiable. These studies gave promising results but...
Development of a Computer Aided Decision Process for Channel Rehabilitation and Watershed Enhancement Techniques
To assist the engineer in planning and design of channel stabilization measures, an expert system (CADWET) was developed using a commercially available expert system shell program. The...
Use of Linear Programming for Hydraulics Problems
Water is becoming a more and more precious commodity worldwide with each passing day. At the same time, the optimum and most productive solutions to water control and utilization are becoming...
Equivalence Between Regular and Irregular Waves in Movable-Bed Models
Laboratory experiments were conducted to evaluate various irregular wave parameters to determine which provides the best match for the regular wave parameter used to develop design guidance....
The Calculation of Flushing Flows for Gravel and Cobble Bed Rivers
Flushing flows are needed to remove fines and sand from a gravel or cobble bed river. A natural stream will have periodic high flows adequate for flushing of fines and sand, but the hydraulic...
Physical Forces Generated by Barge-Tow Traffic Within a Navigable Waterway
Movement of navigation traffic such as barge tows within a restricted inland waterway such as the Illinois, Mississippi, or Ohio Rivers can and will alter the flow field in and around...
Flow Field Near an Inland Navigation Tow
As a vessel moves through a body of water, disturbances are created in the form of altered water levels such as waves or drawdown and altered flow fields such as increased velocities and...
Data Acquisition for Determining the Physical Impacts of Navigation
Research is being conducted to determine the physical effects of navigation on the Upper Mississippi River System (UMRS). Extensive field data on various aspects of physical effects of...
Prototype Measurements of Flows Induced by Navigation Tows
Present projections of growth of commerical navigation traffic indicate that annual tonnage per tow and/or number of tows will continue to increase through the foreseeable future. In order...
Pump Selection Program and a Better User Interface
Numerous highly innovative computer solutions to engineering problems are of little use to the practicing engineer because these programs are not supported by adequate user interface....
Compact Pump Sump Design
This paper details the design criteria chosen to construct a pump sump within several on-site constrictions. The physical size restrictions of the site necessitated the construction of...
The Equivalence of Path and Node Methods for Water Distribution Network Analysis
