Efficiency Testing of Water Wells
In the operation of a water well, the difference between the water level in the well before pumping starts and after it has been pumping for a period of time is termed 'drawdown.'...
Rehabilitation of Water Wells
The main causes of declining well yield are biological growths, mechanical clogging and chemical encrustation. Because the treatment of the causes of encrustation and clogging is expensive...
Pump Selection Program and a Better User Interface
Numerous highly innovative computer solutions to engineering problems are of little use to the practicing engineer because these programs are not supported by adequate user interface....
Compact Pump Sump Design
This paper details the design criteria chosen to construct a pump sump within several on-site constrictions. The physical size restrictions of the site necessitated the construction of...
Coronarization of the Autonomous Water pump
The conventional hydraulic pressure multiplier has been successfully used by Belgian technician Robert Houman (1986) to provide a dependable source of water supply to the NATO-base at...
Research and Development of Wave Pump
A new device, 'Wave Pump' is introduced here. The authors present the mechanism of the system, the analytical method for discharge rate, the hydraulic model test...
Upgrading Antique Sewers
In a $35 million, four-year program, the Massachusetts Water Resources Authority (MWRA) completely restructed the pumping system serving the sewers under East Boston, Chelsea, Revere and...
Down on the Farm
A `total approach' to sludge handling, from nitrogen management to sub-surface injection lines, helps grow corn in Colorado. Engineers have gone a long way to keep things...
Pressure Relief Design Around Pumping Plants
Hydraulic transient protection for an irrigation pipeline pump station can include optimized operating procedures, or design of surge relief equipment such as surge relief valves, and...
Continued Development of the Columbia Basin Project?A Status Report
The Columbia Basin Project is located in central Washington State and encompasses approximately 1 million irrigable acres. Water from the project delivery system was first applied in 1952...
Application of DDDP for Optimal Daily Operation of the Niagara Generating System
This paper describes the application of Discrete Differential Dynamic Programming (DDDP) to determine the optimal operation of Ontario Hydro's Niagara Generating System, on...
Control of Water Distribution Systems: Program Descriptions
The paper describes the operation and features of a suite of computer applications programs. These have been developed within the Leicester Polytechnic Water Control Unit for analysis,...
Graphical Canal Model for System Operators and Planners
Contra Costa Water District operates the Contra Costa Canal, part of California's Central Valley Project. Hydrocomp, Inc. developed an interactive graphical model of the canal...
Optimal Real-Time Pump and Irrigation Scheduling for Center-Pivot Sprinkler Systems
A comprehensive scheduling algorithm is presented for optimally integrating irrigation and pump operational decisions in center-pivot sprinkler systems. Dynamic programming successive...
Analysis of Pumping Station and Force Main Networks
A computer program to simulate the performance of wastewater pumping station and force main networks is discussed. Results are presented which compare system performance for steady and...
Special Hydraulic Problems Related to Coastal Louisiana Drainage Systems
The urbanized coastal areas of southeast Louisiana present unique problems for hydraulic engineers. These problems relate to the design of drainage systems serving leveed areas with flat...
Model Study of New Madrid Pumping Station
The proposed pumping station on the New Madrid Floodway consisted of a draft tube type sump design (referred to as a formed suction inlet) to eliminate swirl and provide a more uniform...
Underwater Tunnel Inspection by Virginia Power Using a Submersible Robot
The Bath County Pumped Storage Station, has three large tunnels linking the upper and lower reservoirs. The 'Hydrover' submersible remotely operated vehicle (ROV)...
Localized Mixing for Improvement of Hydropower Releases from J. Percy Priest Reservoir
The J. Percy Priest Project, located on the Stones River near Nashville, TN, experienced low dissolved oxygen (DO) in the tailwaters during hydropower generation. Using commercially available...
Development of High Specific Speed Pump-Turbines
The operational range of pump-turbines is continually increasing, especially in the direction of high specific speed installation. In this context, high specific speed refers to units...
