Identifying Causes and Predicting Effects of Bank Erosion
A number of causes of bank erosion in natural and disturbed environments are listed and described. Practical methods of predicting rates and directions of erosion in natural environments...
Single-Channel Alluvial Fan Hydraulics with Application to Design of Medium-Density Projects
Methods to identify flood hazards on alluvial fans are provided by the Federal Emergency Management Agency (FEMA) in their Flood Insurance Study, Guidelines and Specifications for Study...
Hydraulic Design of the Unser Boulevard Crossing
As an integral part of the design process, a comprehensive hydrologic, hydraulic and sediment transport analysis was completed of the proposed Unser Boulevard crossing of Calabacillas...
A Stochastic Approach to Sediment Transport in Alluvial Rivers
A dimensionless sediment transport function relation for alluvial rivers has been developed using stochastic approach. The dimensionless function may be applied to estimate suspended load,...
Bank Protection at the Middle and Lower Yangtze
The Middle and Lower Yangtze runs through alluvial plains about 1800 km. There are mainly three types of river reaches: straight-slightly sinuous, meandering, and braided. This paper outlines...
Empirical Methods in the Design of Ground-Water Quality Monitoring Strategies
Ground-water quality monitoring strategies are designed for environments ranging from the complex to the very simple. Complexity is characterized by socio-economic, public health, and...
Application of Hydrodynamic and Water Quality Models at a Superfund Site in Montana
The water quality model applied to the site is the EPA-supported hydrodynamic and water quality model WASP4 with a modification to enable it to better simulate riverine systems. To provide...
An Ongoing Investigation of Residual Suspended Material Transport in Central San Francisco Bay, CA
A study of suspended material transport in San Francisco Bay, California, is presently underway by the U.S. Army Corps of Engineers. This paper describes preliminary numerical model and...
Risk-Cost Principles for Dam Safety Analysis
The purpose of this paper is to present the principles and issues of risk-cost analysis as they have evolved in the evaluation of dam safety improvements. The paper also reviews some results...
Extreme Flood Probability Estimates in Practice
Selecting the safety design flood for a dam or siting structures where flooding would cause severe social or economic disruption requires balancing the likelihood and consequences of failure...
Impact of Risk-Based Analysis on Hydrologic Design Practices
This paper provides a brief review of the current hydrologic design practices of the U.S. Army Corps of Engineers (USACOE) for safety inspection of dams and the current hydrologic design...
Borden Field Data and Multivariate Geostatistics
A large-scale field experiment on natural gradient transport of solutes in groundwater was conducted in an unconfined sand aquifer in Borden, Ontario by extensive monitoring after the...
Sediment Ramping at Mill Creek
A Corps of Engineers study completed in 1988 analyzed this ramping phenomenon Mill Creek in Southern California Using an approach which combined sedimentation research with Corps experience...
Calibrating a 2-D Fate and Transport Model of Watts Bar Reservoir
A branched two-dimensional water quality model has been developed and tested for the Watts Bar Reservoir, including the Clinch River and Emory River embayments. The general stratified...
Sediment Basin Design Using 2-D Techniques
A set of procedures for the design of sediment basins is outlined; it is based on two-dimensional hydrodynamic analyses, in contrast to conversional practice which has used only one-dimensional...
Southwest Pass Training Structure Alternatives
The U.S. Army Engineer Waterways Experiment Station system of computer programs, TABS-2, was utilized to evaluate various structural plans for increasing channel velocities and sediment...
Channel Changes in the Platte River, 1926?1986
The Platte has changed significantly during the last century. A meandering channel with extensive riparian vegetation growth has replaced, the once braided and unvegetated channel in some...
Deposition at a New Dam Near Mount St. Helens
A sediment retention structure (SRS) is being constructed on the North Fork Toutle River in the state of Washington to trap sediments eroding off the 1980 Mount St. Helens debris avalanche....
Sediment Evacuation System for Impounded Rivers
Current solution techniques for the reservoir sedimentation problem are presented and their rationale questioned. The need for focusing on the overall river transport regime is emphasized....
Trashrack Cleaning?A Job Requiring Utmost Care
During the last few years, the tendency in most industries has been towards more automation. Hydro has been no exception. Trashrack raking machines have followed this trend, and automatic...
