Study on Hydrologic Response Via Channel Network Geomorphology
A drainage basin consists of slopes and channels. Slopes are the main fields at which rainfall input is converted into discharge. Stream-channels are the main fields at which the discharge...
Evaluation of the ARS Low Drop Grade Control Structure
The ARS low drop grade control structure was developed by Little and Murphy to provide efficient energy dissipation and effective grade control for streams in northern Mississippi. The...
Municipal Stormwater Management Ordinance Development and Implementation in Pennsylvania
This paper discusses the critical planning and engineering components of a sound stormwater management ordinance and how they can be shaped to avoid commonly encountered basin-wide implementation...
Urban Stormwater Management Practices: Concepts and Misconceptions
A variety of methods are practiced for the management of urban stormwater runoff. These include detention basins/ponds, retention basins, infiltration basins, and seepage pits. This paper...
Evaluation of Streambank Erosion Control Demonstration Projects
The Streambank Erosion Control Evaluation and Demonstration (SECED) Act of 1974 (Section 32 of Public Law 93-251) was enacted by Congress to obtain information on costs and performance...
Computer Watersheds
As development extends further and population densities increase, old methods of stormwater management become obsolete. Runoff from one site can cause flooding elsewhere in a watershed;...
Recharging Ground Water
For more than 55 years, the Orange County Water District has been responsible for the protection and management of the extensive ground water basin which lies under Orange County, California....
Simulated Effects of Climatic Change on Runoff and Drought in the Delaware River Basin
Various projection of climatic change were applied to watershed models of the Delaware River basin. Simulations indicate that a warming could reduce annual runoff by as much as 25 percent...
Great Lakes Waters: Too Little or Too Much?
Water supplies in the Great Lakes Basin, the world's largest fresh water supply, are more than adequate to meet current and projected needs. However, supplies could become...
Corps of Engineers Drought Management Experiences
The drought of 1988-89 was one of the most severe on record for many regions of the United States. Its severity can be measured in terms of the areal extent of hydrologic impact, the record...
Making Amends with Nature
The U.S. salmon population has been decimated in the last half-century, principally because of hydropower. In the nation's focus on alternate and clean energy sources, fish...
Importance of Aeration Basin Detention Time in the Activated Sludge Process
Aeration basin detention time is a key design parameter for an activated sludge system at a wastewater treatment plant. The impacts of reducing the aeration time is illustrated by a case...
Savannah River Basin Drought Contingency Planning
Beginning in 1986, and continuing through the present time, the worst drought in recent history created severe water shortage conditions over extensive areas of the southeastern United...
Shoreline Vegetation and Retention Basins
Erosion of exposed shorelines often introduces large quantities of sediment into the stored waters of stormwater retention basins. This additional sediment load can minimize the water...
Continued Development of the Columbia Basin Project?A Status Report
The Columbia Basin Project is located in central Washington State and encompasses approximately 1 million irrigable acres. Water from the project delivery system was first applied in 1952...
Interbasin Transfers: An Issue in Search of a Policy
Increasing demands for water combined with recent droughts have increased the search in many regions for new sources of water. High on the list of alternatives are always interbasin transfers....
Estimating Impacts of Irrigation on Streamflow
This paper presents a method for estimating the impact of irrigation withdrawals on streamflows and shows the application of that method to the Kankakee River Basin of Illinois and Indiana....
Development, Calibration and Application of Runoff Forecasting Models for the Allegheny River Basin
The computer program HEC1F, developed by the Corps of Engineers' Hydrologic Engineering Center, performs runoff forecasting. The focus of this paper is on application of HEC1F...
Operational Forecasting in Complex River Basins with SSARR-Micro Versus Mainframe Computer
The Streamflow Synthesis and Reservoir Regulation, (SSARR), model has been used for many years for river forecasting and reservoir system modeling in the Columbia River Basin. Operational...
Methods and Applications of Numerical Hydrology on a Drainage Basin
A model is presented here (MOMID) to study, having considered a morphological base of the drainage basin, the unit hydrogram and the routing time along the basin itself....
