Renewing San Diego Pumping Station No. 64
Pump Station 64 has experienced a number of sewage overflows into Penasquitos Lagoon since 1979 (57 in total). The California Regional Water Quality Control Board (CRWQCB) issued a Cease...

Vibration and Vortices at Laguna Verde CWS Pump Intake—A Case Study

Sanitary Sewer System Modeling for Operation and Planning
Development of a Steady State Sanitary Sewer Simulation (S5) computer model helped Newport News, Virginia, enact an efficient sanitary sewer management...

Pumped-Storage Project Site Selection
The paper presents a case history in the selection of a site for a large pumped-storage project for Oglethorpe Power Corporation. The case history illustrates how a large number of potential...

Artificial Recharge of Ground Water via Paddy Fields in an Alluvial Fan, Northern Japan
Artificial ground water recharge via paddy fields was tested during the winters of 1985/86 and 1986/87 in order to protect declining water levels. The purpose of this paper is to discuss...

Design Data of Pump-Turbine and Francis Turbine Units
Some basic statistical data covering geometrical and energy parameters for Francis turbine and Pump-turbine units are presented. These data are further compared as specific ratios for...

Recovery Efficiency From Single-Well Injection/Recovery Tests in a Limestone Aquifer of High Secondary Porosity
An analytical advection-diffusion model was developed to assess the feasibility of injecting and recovering water in a limestone aquifer of high secondary porosity. The model was calibrated...

Dynamic Measurements and Analysis of Vertical Pumps

Oil Pollution in Suexz Gulf of the Red Sea
The population along the Red Sea coast is small, but this sea is now one of the most important areas in the world, for it is the route for ships using the Suez Canal. Many vessels transit...

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,...

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...

Analysis of Large Scale Water Distribution Systems

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....

Effect of Length of Precipitation Record on Recharge Estimates
The effect of the length of precipitation record on groundwater recharge estimates is examined using data from eleven precipitation gages located on the Nevada Test Site. It is concluded...

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...

Women, Water, and Windmills—An Approach to Third World Water Supply

Sand Bypass System at Oceanside, California
This paper describes the design and development of an experimental sand bypassing and channel maintenance system using jet pumps and fluidizers. The system was developed as a possible...
