Underwater Testing in the Development of EVA Support Systems
The ability to simulate realistic zero-g conditions on Earth is of prime importance in determining if various orbital operations associated with extravehicular activity (EVA) can actually...
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...
Ground Water Management: Los Angeles Coastal Plan
In the early 1950s sea water intrusion became a serious problem and led to adjudication of the ground waters and the construction of an injection barrier to sea water intrusion. The general...
Pioneer Conjunctive Use Program in the Southern San Joaquin Valley
The Arvin-Edison Water Storage District is located in the southern end of the San Joaquin Valley of California. The District is a pioneer in using conjunctive use operations to overcome...
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...
A Flood in the Desert
Since 1982 the Great Salt Lake has risen from an elevation of 4,200 ft above mean sea level to a historic high of 4,211.85 ft in June 1986. The sharp rise in the lake has caused considerable...
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...
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...
Predicting Equipment Failure
At Cleveland's Westerly Water Pollution Control Center, the physical/chemical plant for treating wastewater is one of the largest of its kind, with 50 mgd average capacity....
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....
Top Projects of 1987
Five notable entries in the 1987 Outstanding Civil Engineering Achievement competition are summarized. The Keehi Interchange of the H-1 Freeway in Honolulu is only 1.9 miles long, but...
