Cooperative Approaches in Achieving Additional Water Conservation at Prado Dam
The Orange County Water District (OCWD) has successfully negotiated multi party agreements that provide for the use of Prado Basin for water conservation while ensuring protection of the...
Probabilistic Approach for Cancer Risk Assessment
Carcinogenic chemicals have entered ground water systems from surface spills and leaching from subsurface disposal sites. Of particular interest in this study was the contaminant tetrachioroethylene...
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,...
Small Inocula Can Effect
This is the first report of colonization of soil by small numbers of a genetically engineered microorganism. The study suggests that the addition of small inocula of D5 to contaminated...
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
The purpose of this study is to compare the pollutant removal effectiveness of selected wetland vegetation such as cattails, reeds, and bulrushes by using laboratory bucket wetlands. Pollutants...
Use of NaOH to Control pH for Solubilization of Waste Activated Sludge
Waste activated sludge was collected from the final clarifier of a local municipal wastewater treatment plant. NaOH was used in comparison made of the controlled pH batch experiments with...
Design and Implementation of On-Farm Surface Drainage Projects in the Humid Tropics of Mexico
In the humid tropics of southeastern Mexico, the Mexican National Water Commission (CNA) has constructed a network of collector drains for stormwater runoff removal. At the same time the...
A New Strategic Management of Pumping Station in Sewer Systems
Pumping stations are literally the heart of most sewer system operations and sewage treatment plant processes. Current studies show that a small improvement of pump efficiency will offer...
Computer Optimization of a Groundwater Treatment Facility
A computer model has been developed to optimize the operation of a groundwater oil recovery treatment plant. The site consists of 24 pump and treat recovery wells which lead to a treatment...
Risk-based Analysis of Major Rehabilitation of Hydraulic Structures Using REPAIR
This poster session presents a demonstration of a computer model developed by the Corps of Engineers to analyze investment proposals. The primary purpose of the model is evaluate investments...
Biodegradation Modeling of a Closed Landfill Site
The two-dimensional model, BIOPLUME II, was applied to the closed Becker County Landfill at Detroit township, Minnesota, to study the transport of hydrocarbons occurring at the site. The...
CHEMFLO Modeling of Aquifer Bioremediation in Vadose Zone
This paper deals with bioremediation in the vadose zone with an emphasis on using numerical models as a tool to ensure that the concentration of nutrients is maintained at a required level....
Assessment of the Surface-Water Pollution and Measures for Emergency Stations Warning in the Republic of Uzbekistan
In the Republic of Uzbekistan, a special system operates that is designed for the observations on the quality and ecological state of the river ecosystems including: 1-hydrochemical control...
