Agricultural Water Conservation Programs to Improve Water Use Efficiency
California's growing population poses an ever increasing demand for water from the existing limited and scarce water resources of the State. In addition the continuation of six years of...

Impact of Groundwater Management Act and CAP Water Supply on Agricultural Water Conservation Programs
Irrigation districts in central Arizona have increased the tax assessments for their farms to pay for distribution systems to deliver Central Arizona Project (CAP) water. Many farms must...

Agricultural Water Conservation Programs in the Lower Colorado River Authority
Rice irrigation is the largest application of water within the area served by the Lower Colorado River Authority, accounting for approximately 75 percent of total annual surface and ground...

Agricultural Water Conservation Technology Transfer
Efforts to implement computer programs which encourage water and energy conservation in the Columbia Basin, are described. Irrigators use the irrigation scheduling program to receive recommendations...

Price Elasticity and Conservation Potential
Water conservation programs usually contain pricing incentives for users to limit water consumption. This analysis uses data from the Portland, Oregon water system as an example of both...

Seasonal Rates?The Pros and Cons: A Case Study
The Spring Valley Water Company, an investor owned water utility serving over 58,000 customers in Rockland County, New York, implemented a seasonal differential rate structure in 1980....

The Evolution of Conservation Rates in Phoenix, Arizona
Conservation or increasing block rates first implemented in Phoenix, Arizona in 1982 were reexamined by a three year study involving Water Department staff, a Citizen Rates Committee and...

Optimal State Feedback Estimation in Groundwater: Application to Leaky Aquifers
The problem of groundwater flow in leaky aquifer is looked at from a stochastic point of view. Optimal estimation of hydraulic heads are achieved using Kalman filtering. The Kalman filtering...

Flow Investigation for Landfill Leachate
A two-dimensional unsteady-state moisture flow model has been developed in order to describe the leachate flow process in a landfill. The unsteady variation of leachate mound head has...

The PULSEQUAL Model: Using Combinations of Simple Mathematical Equations to Evaluate Complex Storm Effects on Water Quality
Storm discharges (stormwater and combined sewer overflows) have transient and highly variable impacts on receiving waters. Simple water quality equations have been developed to accurately...

Implementing a Watershed Plan for Lake Stevens
The water quality of Lake Stevens is declining because of watershed nonpoint pollution and cycling of nutrients from lake sediments. Hypolimnetic aeration and an alum treatment are proposed...

Design of Aquatic Treatment Systems
This paper describes the design parameters and operating procedures used for a nonpoint pollution/stormwater treatment facility known as an Aquatic Treatment System to be located in the...

Selection of Optimal Best Management Practices (BMP's)
The National Pollutant Discharge Elimination System (NPDES) urban storm water program requires municipalities to remove non-point source (NPS) pollution to the 'maximum extent practicable',...

Urban Runoff Considerations in the Design of Wastewater Management Programs for Coastal Areas
The continuing increase in the population of the nation's coastal areas is placing additional stress on coastal aquatic systems faster than it can be reduced through improved wastewater...

Urban Stormwater Runoff Control System?Village of Skokie, Illinois
Combined sewer systems in many communities lack the capacity to convey stormwater runoff from even small to moderate storm. This inadequate capacity, in turn, causes basement flooding...

Storage/Treatment Isoquants for CSO Control Planning
A quantitative procedure which identifies the technically efficient combinations of storage volume and treatment rate necessary to achieve various levels of combined sewer overflows (CSO)...

Receiving Water Quality Bases for Evaluating CSO Control Alternatives
Waters receiving combined sewer overflow loadings in the vicinity of Bangor, Maine include the Kenduskeag Stream and the Penobscot River. The city's facilities planning effort was performed...

Application of the Storm Water Management Model in Evaluating Combined Sewer Overflows
This paper summarizes the application of the stormwater Management Model (SWW) to isolate the contributions of Combined Sewer Overflows (CSOs) to a receiving water. The CSO discharges...

The Kettering Community Demonstration Project Non-Point Pollution Control and Environmental Enhancement Program
With the advent of the U.S. EPA's municipal/ industrial NPDES and Coastal Zone Management programs the development of effective non-point pollution control programs has become the most...

Storm Water Management in the Greater New Orleans Area
Two parishes, Orleans and Jefferson, located within the Greater New Orleans area have been identified by EPA as urbanized areas requiring storm water permits. Storm water management has...
