Measuring Resuspension of Sediment by Barge Tows
An earlier effort to measure resuspension of sediment relied on U.S. standard depth-integrating sediment samplers. In designing a new effort to collect field data on resuspension, the...
Earthquake Effect on Sediment in Rivers and Deltas
Many authors have studied the age and distribution of the Holocene deltaic deposits of the Mississippi River. Several others have written about the magnitude and the recurrence interval...
Intrusion of Turbid Water into a Two-Layer Stratified Environment
The horizontal intrusion of a turbid water with some intermediate density spreading on the interface of a two-layered homogeneous body of water is investigated. The study is directed towards...
Sedimentation in Mud Mountain Reservoir at High Discharge
Mud Mountain Dam is a single purpose flood control project completed in 1948 on the White River in the State of Washington. The White River drains the northern and northeastern slopes...
Reservoir Sedimentation Mathematical Modeling
The main objective for this paper is to show how one can predict the sediment movement, and estimate the volume of the deposited sediments, which is considered as one of the factor affecting...
Top Projects for 1989
Transportation-related projects, most notably bridges, dominate the 1989 OCEA projects, but each of the 11 improved the quality of life of people in the community without harming the environment....
Scour Assessment at Bridges
Due to the key role that bridges play in the national transportation system, the Federal Highway Administration has developed a scour evaluation program. This program, issued in the form...
Scour Protection at the Straight Drop Spillway
Tests were conducted to determine the scour and the effect of tailwater on scour downstream of the straight drop spillway stilling basin. Preliminary results are presented on performance...
Analysis of Local Scouring
An understanding of local scouring is very important for the safety and integrity of hydraulic structures. The location, shape, and magnitude of the scour hole is a function of dynamic...
Implementation of FEMA Guidelines on Alluvial Fans
This paper provides a general basis for analysis and mapping of flood hazards on alluvial fans. Federal Emergency Management Administration (FEMA) alluvial fan methodology is discussed...
Application of Hydraulic and Sediment Transport Principles in the Design of Tidal Exchange Structures
This paper presents a procedure for the analysis and design of tidal exchange structures, such as tidal gates and training dikes. In lieu of over generalized theories or complicated modeling...
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...
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...
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...
