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;...
Irrigation and Drainage
This proceedings consists of 70 papers presented at the National Conference on Irrigation and Drainage sponsored by the Irrigation and Drainage Division of the American Society of Civil...
Commuting Computing
Portable computers come in many different shapes and sizes and boast many of the same features as desktop machines. Unlike desktop PCs, however, the key to getting the most use out of...

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...
The CADD Landfill
Designing landfills with CADD, engineers have reduced cut and fill calculations from two weeks to two days. Aerial surveys arrive on magnetic tapes and are loaded into computers by in-house...
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...
Anaerobic Biological Reduction of Selenate
When soils with high concentrations of naturally-occuring selenium are irrigated and drained, selenium is leached from the soil and appears in the drainage water. Selenium has caused death...
