Lake Zephyr Watershed Stormwater Management Plan
Zephyr Creek, located near the City of Zephyrhills in west-central Florida, annually experiences flooding caused by rainfall. Development has encroached into the floodplain causing homes,...
Evaluation of Conjunctive Use and Drainage Reduction Strategies
Optimal drainage management strategies for control of salt and selenium contamination problems in the San Joaquin Valley of California must recognize subregional differences in groundwater...
Modeling Groundwater Flow in San Joaquin Valley
Water supply, reallocation and conjunctive use options, within the San Joaquin and Tulare basins of the Central Valley of California, are being considered by Federal and State Planning...
Optimization of a Groundwater Well Monitoring Network
An optimization model is presented for the design of a well monitoring network for groundwater quality and quantity parameters. The model utilizes a geostatistical procedure to estimate...
Groundwater Quality Network Design
This paper presents a methodology that uses optimization for designing a groundwater monitoring network. The methodology incorporates parameter estimation in conjunction with a numerical...
Development of an Optimization Model for Groundwater Withdrawal
An optimization model has been developed to simulate optimal values of withdrawal from a given aquifer system. The linear programming technique has been used to formulate the objective...
Effects of Water Erosion Processes on Drainage and Irrigation Systems
This study examines the relationship between geomorphic processes and drainage/irrigation projects. It illustrates the method of geomorphic analysis by the study of a drainage project...
Effects of Surface Drainage on Sediment Yield in Southern Delaware
Sediment surveys were conducted over a period of 16 years on two small reservoirs in the Nanticoke River basin, Delware in order to assess the effects of watershed drainage projects on...
Evaluating Spring Flow Trends at Pipe Spring National Monument and Vicinity, Arizona
A study conducted by the National Park Service Water Resources Division is resolving if ground water pumping is causing spring flow declines at Pipe Spring National Monument (PISP). Ground...
Conjunctive Use of Surface and Groundwater
A computer model was developed by T. Sammis and Z. Samani to simulate the conjunctive use of surface and groundwater. The model consisted of a groundwater simulation subroutine and a crop...
Neutron Meters in Statewide Irrigation Programs
These programs have ranged from University demonstrations of new technologies on through completely locally funded and operated programs. The most significant interest has been from those...
Effects of Surface Drainage on Sediment Yield in Southern Delaware
Sediment surveys were conducted over a period of 16 years on two small reservoirs in the Nanticoke River basin, Delaware in order to assess the effects of watershed drainage projects on...
Soil Water Movement in Glacial Till: A Case Study in Central South Dakota
Between 1985 and 1987, the CENDAK Drainage Steering Committee conducted several investigations to assess the drainage needs for a proposed large-scale irrigation project in central South...
Strategies to Reduce Salt Load in Drainage Water
A study of irrigation efficiency, drainage flow and trace element loading in the drainage water from a 14000 ha irrigation district on the west side of the San Joaquin Valley of California...
Reduction of Deep Percolation and Drain Water
Management of irrigated agriculture for control of toxic trace elements in agricultural drainage waters must include consideration of a variety of factors and their interactions with one...
Deep Percolation, Drainage and Water Quality
The purpose of this study is to illustrate and and qualitatively describe results of steady and transient numerical simulations examining the influence of drain spacing and depth on shallow...
Artificial Recharge in the Southern Ogallala?Experiences with Playa Lake Water and Filter Underdrains
Ground water in southern portions of the Ogallala Aquifer has declined significantly over the past several years. Attempts to recharge playa water in the past have failed due to the clogging...
Economic factors of Drainage Water Reduction
Properly designed and maintained pressurized systems provide better irrigation control and greater infiltration uniformity. But irrigation costs are increased. Imposition of drainage water...
Blending Saline and Non-Saline Waters Reduces Water Usable for Crop Production
The purpose of this paper is to provide theoretical and conceptual evidence to show that water quality protection programs which dispose of agricultural drainage waters through blending...
Kesterson Crisis: Sorting Out the Facts
The United States Bureau of Reclamation (USBR) began planning and construction activities in the mid-1960's for the San Luis Drain, a master drain to dispose of salt-laden...
