Agricultural, Meteorologic, and Hydrologic Drought Relations: Applications to Irrigation and Water Supply Planning
Meteorologic and hydrologic factors can combine to significantly reduce crop yields, leading to an agricultural drought. Agricultural and hydrologic droughts affect a large segment of...

The Water Erosion Prediction Project: Erosion Parameter Estimation
The USDA Water Erosion Prediction Project (WEPP) includes a large field program for collection of experimental data to evaluate soil erodibility. Rainfall simulation techniques are used...

The Influence of Water Tables on Herbicide Losses
Atrazine and metolachlor were applied preemergent on April 22, 1987, to silage corn on high watertable fields which were either subsurface drained (104 mm drain tubes 1 m deep) or surface...

Formulating a Coastal Plain Water Quality Project
In 1988, the Soil Conservation Service in Delaware helped local sponsors prepare a detailed preauthorization planning report for water quality improvement in Indian River Bay watershed,...

A Review of Water Table Management & BMP Effects on Selected Nitrogen Processes
This study addresses the combined impacts of water table management (WTM) and best management practices (BMP's) on surface and ground water quality. DRAINMOD (water table...

Managing Water Table Management Systems for Water Quality
The purpose of this paper is to briefly summarize the results of water quality studies related to water table management conducted in North Carolina over the past 15 years. Results of...

Development and Application of a Model for Urban Use of Reclaimed Water
Water for nonpotable uses can be obtained from lesser-quality sources, and reclaimed water represents a very valuable and relatively unusual source. The planning and design process for...

Determination of Optimal Capacity for Water Imports
Determination of the optimal size of water import facilities is inextricably related to the issue of establishing the optimal water price, and is made more difficult by the stochastic...

Mathematical Modeling of Water Balance in a Well Defined Pilot Area
This study developed a water balancing computer code, a type of book keeping method using a detailed version of the hydrologic balance equation. The purpose was to provide a method of...

Drought Investigations by the Use of Maximum Daily Temperatures
By the use of maximum daily temperature data, drought events can be defined by taking a certain truncation level to form the partial drought duration series. A drought series representing...

Locating and Sizing Air Release Valves on Irrigation Systems
This writing is directed to persons involved in irrigation systems and describes the usage of air release and vacuum valves. Principles described are applicable to many other piping systems,...

Interbasin Transfers: An Issue in Search of a Policy
Increasing demands for water combined with recent droughts have increased the search in many regions for new sources of water. High on the list of alternatives are always interbasin transfers....

Water Allocation in the Bay/Delta (California)
The California Water Resources Control Board is conducting hearings, over the period July, 1987 to 1991, to review beneficial uses of the water tributary to, within, and exported from...

Water Marketing in California
In one of the world's consummate entrepreneurial environments, a commodity as vital as water is so difficult to buy and sell. Why has water marketing become widely used in...

Evolution of Water Allocation Law in the Eastern United States
During the first half of this century, the riparian doctrine and common law ground water doctrines were modified by the courts as they adjusted to changing social demands. Evolution has...

State Financing of Soil Conservation Programs
Federal financial incentives to implement conservation programs under traditional programs probably will not increase. Any increases in present financial incentives and new incentive alternatives...

Implementing a Groundwater Control Board
Memphis, Tennessee, situated on the banks of the Mississippi river, has never utilized this vast resource for water supply. Instead, Artesian wells have supplied the Memphis, Tennessee...

Dam Replacement Insurance
Most dam owners recognize that the dams they operate are critical structures, both to water users as well as downstream floodplain occupants. Loss of the structure use has significant...

Attitudes and Health Effects of Water Reuse
This paper is concerned with public attitudes toward water reuse for irrigation and with the consequences of human contact with reclaimed wastewater. Initially, attitudes are considered...

Water Resources Planning for the San Antonio Region
Water resources planning for the San Antonio region begins with the physical setting and the technical considerations - the science and engineering aspects. It proceeds to the economic...
