Estimation of Unsampled Sediment Discharge
A procedure is developed to estimate the total bed material load without using the size distribution of suspended load. Because of the uncertainties involved in the calculation of the...
Soil Erosion, Sediment Yield, and Deposition in the Illinois River Basin
The amount of soil erosion of the Illinois River Basin was estimated by using the 1982 National Resources Inventory (NRI) and the Illinois Geographic Information System (GIS). The sediment...
Soil Erosion and Sediment Transport Modeling on Small Tropical Watersheds
A fundamentally-based concept of a soil erosion and sediment transport model in a forest tropical area is presented. It will be incorporated to the ANSWERS model. The forest hydrology...
Sediment Yield and Mean Annual Discharge from Watersheds in the Indian Subcontinent
Measurements of sediment deposition in reservoirs located in the Indian subcontinent (India, Nepal, Pakistan) indicate that the rate of sedimentation is much higher than predicted during...
Convective Sedimentation from a Stable Turbid Layer
A set of experiments was conducted to test T Green's criterion for the existence of double-diffusive convective motions at an originally sharp, horizontal interface separating...
Movement of Sediment Mixtures in a Parabolic Flume with Simulated Rainfall
A 4-m long flume with parabolic cross section and adjustable slope was constructed to investigate the sediment carrying capacity and the variation of grain size distribution during deposition....
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...
Surface Roughness with Erosion of Earth Channels
A determination of the stresses effective in soil detachment is essential in determining erodibility. The soil roughness that exists during testing and in natural channels is a key element...
A Computer Model for Gravel Pit Headcut Simulation
Sand and gravel mining activities have led to numerous problems in river management. A review of many complaints on sand and gravel mining indicates that the major concern is structural...
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...
Infiltration of Water to the Ground in a Flood-Control Reservoir with Seepage
As storm water management in urban area with increasing amount of runoff, flood-control reservoir with the bed having large permeability to enrich the groundwater is considered. A dynamical...
Water Resources Planning and Management
The proceedings of the 16th annual Water Resources Planning and Management Conference, which was held on May 22-24, Sacramento, CA, consists of four page extended abstracts for about 200...
Cold Regions Engineering
This volume contains papers that were presented at the 5th International Cold Regions Engineering Specialty Conference, sponsored by ASCE and held in St. Paul, Minnesota, February 6-8,...
Boundary Element Methods in Structural Analysis
Tutorial and state-of-art aspects of the Boundary Element Method (BEM) are combined with applications in structural analysis in order to provide information about the advantages of this...
Electricity From Air
After a decade of research and dozens of feasibility studies at sites around the country, the first Compressed Air Energy Storage (CAES) plant in the U.S. is under construction at McIntosh,...
Tapping A Glacier
The Eklutna water project receives a 1988 Outstanding Civil Engineering Award of merit. The project�a 30 mile pipeline and treatment plant that brings glacial runoff from Eklutna lake...
Agriculture and Groundwater Quality
Nitrates and pesticides used in agriculture cause groundwater degradation. Agricultural practices in the U.S. will have to be changed to alleviate the health effects of these chemicals....
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...
