A Local Approach to Regulating Toxic Air Contaminants
The Monterey Bay Unified Air Pollution Control District began developing a local toxic rule that would apply to a broad number of pollutants and yet be readily usable to a permitting engineer....
Generating Instream Recreational Alternatives
A methodology combining an optimization model and a spreadsheet program is presented to assist resource managers in developing and evaluating instream recreational alternatives. Recreational...
Methodologies to Estimate Instream Benefits for Use in Water Allocation
In the 'utility valuation' approach, the recreational experience possible at given flow levels is examined to derive a utility that the resource provides to the...
Generation of Compromise Alternatives Between Maximum Benefits and Maximum Acceptance
This paper proposes a procedure to generate a set of compromise alternative solutions between maximization of benefits and maximization of acceptance. A small set of near optimal strategies,...
Generation of Multiple Tier Instream Flow Requirements
Multiple tier scaling of instream flow requirements based on available water supply and reservoir storage state is proposed as a means of generating instream flow regimes. Rules for variable...
Effects of Salts on Soils and Plants
Salinity is a major constraint to crop production in many irrigated lands of the world. Management practices are needed for the control of soil and water salinity. The development of appropriate...
Water Quality Criteria for Irrigation
An assessment of irrigation water quality for the concentration of inorganic constituents should consider crop sensitivities, soil properties, such as hydraulic conductivity, reactions...
Irrigation and Drainage Practices
Salinity causes many problems in agriculture, by lowering production or requiring more intensive management on farms, or by degrading off-farm soils and waters. This paper describes causes...
Irrigation Agriculture: Is it Sustainable?
Irrigation in (semi-) arid climates can be managed in such a way that it can be sustained indefinitely. Salination can be avoided by providing adequate drainage. Drainage, however, exacts...
Training Water Delivery System Operators with Simulators
A graphical display training simulator has been developed on a microcomputer to mimic the operation of a multi-reservoir water delivery system. The simulator functions as a training device...
Managing Water Shortage by Regional Cooperation and Conservation
In the New York-New Jersey metropolitan area, water emergencies becoming more frequent events because of increases in water demand and lack of new supply additions. The water supply problem...
Water Management for the Future?State Perspective
The State of Georgia-Environmental Protection Division (EPD) has managed the quality of the waters of Georgia since the early 1970's. Today, the main focus of water issues...
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...
Economic Impacts of Storm Sewer Design Criteria
This paper discusses the selection of storm sewer design criteria and the resulting economic impacts. Using the Rational Method for calculating design flows, an investigation was made...
Urban Stormwater Runoff Management
Local land use regulations managing stormwater runoff in new urban developments are the most practical and effective method to control pollutants in urban stormwater runoff or prevent...
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...
Flood Impact and Management of Levees in Tennessee
The construction of private levees is causing flooding and erosion problems along several tributary rivers in West Tennessee. The severity of these problems is recognized by the State...
Hydrologic Methodology for Evaluating Urban Development
It is recommended that a hydrologic methodology be utilized that contains sufficient parameters to enable the user to evaluate the impact of the changes to the watershed resulting from...
Impact of Detention Storage on Main Stream Flooding
The methodology, results and management implications are presented for a stormwater study at an urban watershed experiencing periodic flooding along the main channel. Local data were collected...
Irrigation and Aquifer Management in Illinois
The ground-water resources in eastern Kankakee and northern Iroquois Counties, Illinois, have been used for irrigation for over 50 years. During the drought of 1988, 131 irrigation wells...
