Sediment and Aquatic Habitat Associations in River Systems
This paper results from the Task Committee's effort to summarize knowledge linking sediment transport and aquatic ecology. This paper presents one element of this work: the...
Sediment Transport, Hydraulic Retention Devices, and Aquatic Habitat in Sand-Bed Channels
Streams and rivers of all sizes and in all parts of the United States flow on sand-bed channels. Scour, Transport, and deposition of sediments particles are natural processes in these...
Sediment Transport and Aquatic Habitat in Gravel-Bed Rivers
Gravel-bed rivers experience dymanic conditions of flow and sediment transport. Long periods of bed stability are interrupted by shorter periods of bed mobility when major changes and...
Storm Water Management and Wetland Restoration?Ballona Channel Wetlands
A storm water management plan was engineered to provide storm water dention necessary for site develop and at the same time to allow wetland restoration. Objectives of the project were:...
River Engineering and Environmental Resources
The federal government and the Corps of Engineers (CE) are committed to preserving and enhancing environmental quality. Research and development support for this commitment in the realm...
Measurement of Hydraulic and Environmental Effects of Aeration Devices in Douglas Reservoir
The releases from Douglas Reservoir experience periods of low dissolved oxygen (DO) content during the summer months. Tests were conducted during August 1989 to determine the effects of...
CCM Overtopping Protection on Three Parkway Dams
Cellular concrete mat (CCM) overtopping protection systems have been designed for and will be installed on three small embankment dams along the Blue Ridge Parkway. Based on recent field...
Delineation of Ordinary High Water
'Ordinary high water' is used in a court of law to delineate the extent of land ownership of adjacent riparian owners on navigable rivers. The most appropriate...
Impact of Agricultural Levees on Flood Elevations
Agricultural levees are used in many low-lying areas to protect farmlands from floods. The levees are often constructed, maintained, and improved on an ad hoc basis by farmers or with...
Modelling of Stages of Nile River as a Tool for a Better Water Resources Management
As far as Egypt is concerned, the Nile is not just a river, it is rather the pulsing nerve of life. Consequently, it was essential to maintain detailed information about its levels and...
Overview of Mathematical Models?River Nile/High Aswan Dam
This paper has been directed towards the presentation of seven reliable planning tools (mathematical models) that can be used for the investigation of the planning options facing policy...
Sacramento's Proactive Stormwater Permit Program
In January 1990, with the encouragement and assistance of the California Regional Water Quality Control Board-Central Valley Region (Regional Board), the City and County of Sacramento,...
Utilization of Stormwater Runoff to Recharge Underlying Aquifer
The expanding economy in Oman has led to rapid development in the Capital area. Water is critical to sustaining this rapid growth, and new sources of water are being sought to meet the...
Dispersion of Tracers Along the Coast of Singapore
The primary objective of the present study is to model numerically the dispersion of a cloud of fine radioactive tracers along the east coast of Singapore. The results of a hydrodynamic...
Slurry Removal From a 2-D Fluidized Region
A two-dimensional fluidization experiment is performed on fine sand with a 5.08 cm diameter source pipe with horizontally opposed orifices, 0.317 cm in diameter, spaced 5.08 cm. Slurry...
A Study on Estimation of Aquifer Parameters in Unsteady Seepage Flow
A method which automatically identifies aquifer parameters is proposed in this paper. The aim of this investigations is to estimate transmissivities and storage coefficients of unsteady...
Three-Dimensional Model of a Stratified Estuary?St. Andrew Bay System, Florida
A three-dimensional modal is applied to a northwest Florida estuary to provide the initial insights into the circulation and flushing patterns of the system. The model, developed by the...
Long-Term Numerical Simulation of Three-Dimensional Hydrodynamics of Chesapeake Bay
A time-varying 3D numerical model of Chesapeake Bay has been developed to provide flow fields to a 3D water quality model of the bay. The water surface, 3D velocity field, salinity, and...
An Acoustic Doppler Discharge-Measurement System
A discharge-measurement system that uses a vessel-mounted acoustic Doppler current profiler has been developed and tested by the U.S. Geological Survey. Discharge measurements using the...
