Selection of generator/motors and other electrical equipment for pumped storage plants requires consideration significantly different than for conventional hydro plants. This is particularly...
Conjunctive Use Study of Groundwater and Surface Water in Chino Basin, California
The purpose of this paper is to study the effects of artificial recharge on an already contaminated unconfined aquifer and propose optimal recharging and pumping schemes to prevent the...
Methodology for the Optimal Reliability Based Design and Analysis of Pumping Systems for Water Distribution Networks
A methodology has been developed for the optimal (minimum cost) reliability based design of pumping systems. Two computer simulators, a reliability simulator and a hydraulic simulator,...
Optimal Pump Operation Using Nonlinear Programming
This paper focuses on the operational control problem of determining the optimal pump operation policy for a given distribution system. The optimal pump policy is defined as that schedule...
Regional Assessment of Pumpage in Southeastern Virginia
A U.S. Geological Survey investigation was conducted, in cooperation with the Virginia Water Control Board, to analyze the hydrogeology and groundwater flow system in the Coastal Plain...
Hydrogeology of a Barrier Island System, Nags Head, North Carolina
The purpose of this research was to understand the dynamics of the water table prior to the start of municipal pumping and to predict the effect that the pumping would have upon the water...
A Ground Water Modeling Effort to Simulate the Results of An Aquifer Restoration Scheme
A ground water model using the IBM PC version of the USGS MODFLOW code was constructed to simulate the ground water flow beneath an industrial site in the central Midwest. A detailed three-dimensional...
Small Diameter Gravity and Pressure Sewers
In communities with low population density or physical features that make conventional gravity sewers inordinately expensive, alternative sewer technologies can be significantly lower...
Infrastructure and Marketing in Water Resources
Marketing and infrastructure are two areas of growing interest and importance in engineering. Nearly every engineering discipline now uses some form of marketing to promote its products...
Water Requirements for Vegetable Production in Puerto Rico
Total water requirements of green beans, cabbage, carrots, cucumber, eggplant, lettuce, melons, okra, onion, potatoes, pumpkin, sweet peppers, sweet potato and tomatoes were estimated...
Control of Surge Pressures in Irrigation Systems
Excessively high or low pressure within an irrigation system can result in damage to pipelines, pumps, valves, and on-farm facilities. Frequently, these pressure variations are caused...
Surface Water Pumps: Model-Prototype Calibration
A Case Study on the Modeling of Suction Scoops to Remedy Pump Intake Problems
The Liquid Droplet Radiator in Space: A Parametric Approach
This study is a parametric investigation of the performance and operating characteristics of a cylindrical Liquid Droplet Radiator (LDR) for use in space. The LDR system mass per heat...
Subsurface Injection of Storm Water Runoff into an Underground Storage of Bangkok
Subsurface injection through a well into sand and gravel formations of the Bangkok aquifer of untreated canal water whose composition considered similar to that of storm water runoff,...
Analysis of Hydraulic Impacts at the Tucson Reclaimed Water Recharge Project
The Tucson Reclaimed Water Recharge site has been implemented with increasingly sophisticated calculation methods as data collection efforts advanced. Initial project scoping utilized...
Performance of an Artesian Glacial Drift Aquifer with Induced Recharge
The City of Kalamazoo, Michigan, has constructed induced recharge facilities at sites of several of its twenty-one well fields as part of a program for supplying potable water to Kalamazoo...
