A Proposed Desilting Reservoir System in Taiwan
The paper discusses the design of a desilting system for Nanhwa reservoir, in which the reservoir is divided into two bays; water flows into the forebay for sedimentation and then over...

Sediment Penetration in Lakes as a Result of Dredged Material Disposal and River Sediment Loads
Pollutant transport within the coastal boundary layer is highly sensitive to the vertical current structure and to the magnitude of the vertical current, especially during upwelling and...

Sedimentation Problems of the California Aqueduct
The California Aqueduct crosses the alluvial fans of many intermittent streams on the west side of the San Joaquin Valley. At two sites where watershed sediment yields were underestimated,...

Sedimentation Processes in Hydrosystems, Numerical-Empirical Modeling
This paper presents the results of a newly developed computer simulation model for studying the sedimentation processes in a variety of hydrosystems. The most effective numerical methodology...

Sedimentation in the All-American Canal
During the planning for the All-American Canal, by the U. S. Bureau of Reclamation as part of the Boulder Canyon Project, works were designed at the head of the canal to remove between...

Land Renewal with Topsoil from Clyde Port Dredgings
The paper examines the potential of using sediment dredged from the River Clyde estuary as a topsoil in land renewal. It presents results, to date (1986), of a study sponsored by the Scottish...

An Optimization Approach for Locating Sediment Ponds in Stripmined Areas
In this study, a mathematical model which can predict erosion from a watershed and incorporated into an optimization model has been investigated. The Erosion-Deposition Model (EDM), which...

The Reliability of Treatment Systems
The purpose of this paper is to present the results of case studies of zero and first order reactor systems and an activated sludge treatment system consisting of a primary settling tank...

Water Erosion from Irrigation?An Overview
Erosion and sedimentation by water includes the process of detachment, movement, and deposition of soil particles (14). Under irrigated conditions, the erosive process is water flowing...

Erosion and Sedimentation Processes in Irrigation
Soil erosion occurs when fluid in motion detaches and transports soil particles. Sedimentation occurs when the fluid transport capacity decreases. Both the hydraulic forces of moving water...

Management Practices for Erosion and Sediment Control in Irrigated Agriculture
Basin irrigating rice can reduce suspended sediment loads in water because the basins serve as sediment retention basins. Furrow erosion causes significant suspended sediment loads in...

Sediment and Erosion Control Implementation: An Overview
The responsibilities of the federal, state and local governments in sediment and erosion control are reviewed. The effectiveness of cost-shared and non-cost-shared technical assistance...

The Effect of Storms on Pollution Loading Estimates
A rather extensive field and modeling program is underway in the Sandusky Bay/Nearshore region of Lake Erie and the objective of this paper is to summarize the preliminary results of a...

Prediction of Sediment Yield for Southern California Watersheds
The objective of this paper is to present a scientific method based on multiple linear regression analysis between the sediment yield per square mile and a number of physically realistic...

Hansen Dam Sediment Modeling Study Impact of Water Supply vs. Flood Control Operational Modes on Sediment Deposition in the Reservoir Area
The analysis of scour and deposition in Hansen Reservoir by modeling the interaction between the water-sediment mixture, sediment material forming the stream's boundary and...

Annual Sediment Loads of Illinois Streams
Incorporation of sedimentation surveys for 24 Illinois lakes was needed to provide somewhat long-term average sediment yields of Illinois streams. For each suspended sediment station a...

Hydraulic Modeling for Ecological Research
Because of the problems and expenses of a continuous data collection program for large rivers, it was decided to develop an integrated hydrodynamic and biological model for the Illinois...

Water Quality and Hydrodynamics in a Shallow Lake
Hydrodynamics and water quality are closely coupled in a shallow lake via horizontal transport and sediment resuspension. The latter process is examined thru modeling and in situ field...

Submerged Vanes for Sediment Control in Rivers
A procedure is developed for a rational design of a system of submerged vanes for depth control in alluvial-river channels. The vanes are vertical, small-aspect ratio foils installed on...

A Model Relating Water and Sediment Yield to Upstream Agricultural Practices
A physical-process model is formulated to quantify daily water and sediment yield as related to upstream land use, land management, and soil and water conservation measures. This model...
