Use of FESWMS-2DH for the Attaway Road Bridge Repair Project
The paper presents the application of the Finite Element Surface Modeling System: Two Dimensional Flow in a Horizontal Plane (FESEMS-2DH) computer program in the Attaway road bridge repair...
One- and Two-Dimensional Analysis of Flow in Hotophia Creek, MS
A numerical experiment on the influence of a sand bar encroachment on the stream flow pattern is reported. The results of a two-dimensional analysis were compared with results of an equivalent...
1993 Ground-Water Flooding in the Havana Area
The Havana area in Mason County, west-central Illinois, experienced nearly continuous rises in the water table beginning in the fall of 1992 which created lakes in depressed areas. Water...
Steep Constructed Stream Channels and Chutes
Research and technology transfer needs are described for steep stream channels and chutes. Iterative processes are presented for design and construction of bouldery channels and chutes...
Evaluating Flow Resistance Using Height of Roughness Protrusions
On the basis of field measurements on the Sumava mountain rivers heights of roughness protrusions have been used for calculation of flow resistance. The result resistance equations, compared...
A Study on Mathematical Model for Sediment Yield in Mountain Regions with Large Hillside Slopes
Based on the characteristics of water and soil loss in mountain region with large hillside slopes in southwest of China, the equations of runoff formation and sediment yield are obtained....
Size Characteristics of Debris Flow Deposition
The size distribution of debris flow deposition is extremely wide which may contain nearly all particles from clay and colloid to boulder. Particle size and composition have very important...
Relation Between Largest Known Flood Discharge and Elevation in Montana
Previous studies relating unit discharge to elevation indicated that large floods in the Rocky Mountains may be limited by elevation. However, high-elevation data are sparse in Montana...
Historic-Flood Evaluation and Research Needs in Mountainous Areas
An evaluation of historic flood estimates in mountainous areas in Colorado was made to assess their accuracy. The purpose of this evaluation is to enhance awareness of the need to assess...
3D model verification for a groyne and harbor experiment
A discussion of 3D model verification and calibration based on measurements in a flume is carried out for different test cases (groyne, harbor). The measurement data is available for public...
Estimation of Design Surge Heights by Utilizing Meteorologic and Oceanographic Data
Data on cyclonic storm surge height have been generated with the help of a statistical simulation model. Data on observed maximum cyclonic wind speed and the length of the continental...
Analysis of Sand Movement on Noto Coast by Geochemical Method
The analysis of sand samples by X - ray fluorescent spectroscopy (abbreviated by XRF) gives the ratio of the geochemical elements to construct the sand samples. This shows the geochemical...
Velocity Control Rings for RC Pipe on Steep Slopes
This paper discusses the use of internal concrete rings to reduce velocity and concrete erosion for reinforced concrete pipes on steep slopes in the Southern California area....
Plunge-Pool Scour by Inclined Jets
A series of experiments were performed in a sand-bed plunge pool with circular jets produced by nozzles at different angles and elevations and conveying different flow discharges. The...
Management of Sediments on the Red River Waterway Project
The Red River is a large alluvial river system with the lower 280 miles currently being developed for shallow draft navigation. The navigation project entails construction of five locks...
An Improved Design of Excluding Sediment into River Intake Structures
The function of excluding sediment into river intake structures is usually achieved by the device of sluice ways. Although many sluice ways have been constructed and many formulas are...
Why Design Storm Methods Have Become Unethical
This paper discriminates between continuous and event modelling, and describes some dimensions of ethical design for sustainable ecosystems. Arguments are presented that event modelling...
Combined Stormwater Drainage and Treatment
Due to continuing public concern regarding environmental protection for the nation's waterways, new and more stringent water quality control regulations have been developed. This is most...
Urban Runoff Based on Land Use and Particle Size
As point sources have achieved pollution compliance, the focus of pollution abatement has shifted to nonpoint sources. New Federal regulations require wet-weather monitoring of drainage...
Non-Point Source Pollution Reduction
The paper reports on the results of a study to determine the effectiveness of the best management practices (BMPs) for use in the Tampa Bay Watershed. The study aims to determine the efficiency,...
