Effects of Sewage Effluent Irrigation on Paddy
Paddy, the staple food of South India, occupies about an area of 38 million hectares in India [1, 1987]. Being a semi-aquatic plant, its water requirements are many times more than most...
A Framework for Sanitation and Health Risk Assessment
This paper summarizes some historical, cultural, and operational responses to risk. Zero risk and zero pollution ideas developed as arguably escapist reactions to stresses of economic,...
Risk-Based Planning and Management of Maintenance Dredging
The U.S. Army Corps of Engineers (Corps) Institute for Water Resources (IWR) is developing and applying a risk-based approach to address maintenance dredging cost, reliability, and budgetary...
Portable Flumes with Adjustable Throats
Vertically adjustable flumes for canal flow measurements address several problems in field practice. One involves the perception by some canal water users that flumes and weirs always...
Water Quality Modeling of the Rouge River Watershed
A relatively detailed modeling framework for calculating pollution flows and loads to the Rouge River has been developed and tested successfully. The framework includes consideration of...
Studies on the Erosion of a Compacted Soil
In the management of water there are certain applications in which compacted soil is used (i.e., dams, embankments, levees, spiliways, and channels). Engineers rely primarily on field...
Sediment Removal from Stormwater Runoff
Sediment traps, also known as baffle boxes, are being used throughout the state of Florida to remove sediment from stomiwater. A baffle box is divided into three compartments by two bathers,...
An Experimental Study on the Use of Constructed Wetlands for Stormwater Management
