Case Study?Closed Pipeline Systems
The paper discusses closed pipeline system and its automation, including variable pumping rates, sensing devices, automatic controls, pressure regulators, flow measuring devices, surge...
Pump Plant Control and Automation
Pumping plants for irrigation systems can be separated into two general types: source pumps which provide water to the system and booster pumps which increase the system pressure. Typically,...
Maintenance of Automated Pumping Plant Controls
Westlands Water District, located in the Central San Joaquin Valley in California (Fig. 1) includes over 600,000 acres of agricultural land and is part of the San Luis Unit of the U. S....
Reliability Analysis of Pumping Stations and Storage Facilities
The methodology presented for pumping stations is based upon three models: a supply model, a demand model, and a margin model. The supply model considers so-called states of a system which...
Evaluting the General Well Function
The closest thing to a mathematical function that maps well discharge to drawdown has been Jacob's equation, caled the step-drawdown equation. However, this equation assumes the drawdown...
Calculating Runaway Pressure Surges in Small Hydro Units
Determination of the runaway speed and concomitant pressure surges requires consideration of both the turbine rotodynamics and the waterhammer equations. In this paper a simplified method...
Evaluation of Surface-Water - Ground-Water Interaction Coefficients in Water-Resources Planning Model
A water-resources planning model formulated as a mixed-integer program is used to screen and sequence proposed projects such that the present cost of meeting future water demands is minimized....
Cleanup on a Large Scale
The San Gabriel Basin yields 200,000 ac ft of groundwater a year from 400 supply wells. This water makes up 95% of the Valley's water supply. Already 30% of the water pumped...
Sewers Get a Breath of Fresh Air
Domestic sewage pump stations and treatment facilities have long been plagued by corrosion and odor problems caused by hydrogen sulfide. It is also extremely toxic. Sulfide production...
Water Supply System Rehabilitation
This report was prepared to assist practicing engineers meet the challenge of rehabilitating old drinking water systems, many of which have been in existence for over 100 years and are...
Criteria for Selecting Turbine-Pumps Used in Mini-Hydro Power Units
The present paper is aimed at studying turbine-pump units operating at low heads. The proposed methodology is based on the global matching of the turbine and the pump so that both will...
Evaluation of a Pump-Storage Hydropower Facility
This paper summarizes the findings of the evaluations conducted by faculty of the University of Missouri and outside consultants regarding the downstream effects of Harry S. Truman Dam...
Phased Pumped Storage Planning and Site Evaluation
A phase process of site evaluation provides for an efficient use of resources while supporting the necessary level of detailed investigation. This paper describes the phased siting process...
The Corps of Engineers' New Hydropower Manual
The Corps of Engineers has recently completed a new Engineering Manual (EM), which outlines procedures used for the evaluation of hydropower projects. It will serve as the basic Corps...
Micro PAT-Synchronous Generator Unit for Isolated Power Supply at Sultan Project Dam
The paper describes a unique application of a micro-PAT Unit installation utilizing downstream release flows for providing an isolated power supply at the Jackson (Sultan) dam in Washington...
Grand Coulee Pumping/Generating Plant
The paper discusses the Grand Coulee Project history, including a brief review of landmark dates and events. Major general features of the Project are covered, including civil works, mechanical...
Blue Marsh?A Modular Hydroelectric Project
The Blue Marsh Hydroelectric Project will be the first complete application of concepts developed in several research studies of modular hydroelectric power plant components. The Department...
Development of the Standardized Francis Turbine
Initial machine selections to address higher head sites included small custom Francis turbines and standard pumps running in the turbine mode. As the former proved too costly and the latter...
Rehabilitation of a Pump/Turbine
Between 1964 and 1968, eight 212 in pump discharge diameter Baldwin-Lima-Hamilton vertical pump/turbines with Westinghouse motor/generators were installed in Philadelphia Electric Company's...
Oxygenation of Releases from Richard B. Russell Dam
