The Water Problems on the Penghu Islands in Taiwan
The Phengu Archipelago in the Taiwan Straits is composed of Pleistocene basalt with the accumulation of coral reefs without any significantly mountainous terrain on any of the islands....
Computer Aided River Basin Management in the Alps
The present paper outlines progress in developing river basin management potential through joint research on several Alpine River Systems including the Avisio, Brenta, and Cordevole. Applications...
In-Situ Microocosms for Calibrating Dynamic Models
The calibration of dynamic water quality models for lakes and reservoirs requires significant quantities of data, experience, and judgement. In particular, the identification of an appropriate...
A New Dam in California?Piece-of-Cake!
It initially appeared that a series of insurmountable roadblocks would prevent the City of Morro Bay from constructing a new dam and water supply reservoir on San Bernardo Creek near the...
Use of Stochastic Hydrology in Reservoir Operation
The Bureau of Reclamation is incorporating stochastic traces to provide a broader basis for management decisions during drought periods for the Central Valley Project in California. A...
Ecological Impacts of Sediment Transport to Tropical Reservoirs
Sediment transport and siltation influence both the longevity and ecology of tropical reservoirs. The sediment load to these systems is typically seasonal and affects ecological processes...
Trash Busters ? A Comparison of Screening Structures for Irrigation Systems
Several irrigation districts in the Pacific Northwest have recently installed screening structures for use in removal of trash from canals, rivers, or reservoirs. Some of the screens have...
The Tunnel that Cleaned Up Chicago
The 1986 Outstanding Civil Engineering Achievement award went to Chicago's Tunnel and Reservoir Plan (TARP) Mainstream Tunnel and Pumping Station. The $975 million project...
Instant Hydro Forecasting
Two new software programs developed by a San Francisco-based engineering firm determine hydropower potential, best site configuration, and best economics for hydroelectric projects. One...
A System Framework for Engineering Risk Analysis
A mathematical system framework is developed to model a series of criteria called performance indices (PI) related to engineering risk in water resources. Such criteria include reliability,...
A Microcomputer Reservoir Decision Model
The paper discusses the development of a dynamic programming model to optimize reservoir operations. Given statistical summaries of inflows, forecasts of near-term inflows, and cost statements...
Hydrologic Simulation for Reservoir Development
Potential changes in the Manasquan River basin hydrologic budget were assessed with the Hydrological Simulation Program in Fortran (HSPF). The HSPF results were used to assess the reliability...
Design Flexibility Cuts Costs
The Los Angeles Water Department saved $5 million on a pipeline project by investigating the capabilities of pipe fabricators to furnish the pipe size required and by being open to alternate...
Logistics for Structures Sealifted to the Arctic
Sohio has successfully pioneered the development of the Prudhoe Bay reservoir by sealifting prebuilt oil processing facilities from the lower 48 states. The experience thus gained is being...
Micro Use in Water Management in the Brazos Basin
The Brazos River Authority, an agency of the State of Texas created to conserve and develop the surface waters of the 42,000 square mile (110,000 km) Brazos River Basin, is in the midst...
Storage Projection for Reservoir Systems
Two methods are studied for determining the probability distribution of future levels of storage in a reservoir system: transient analysis and Gould's probability matrix method....
Design and Operating Rules for Reservoir Storage to Offset Future Consumptive Use
The Washington Metropolitan Area (WMA) relies largely on the Potomac River for water supply. After many years of study, a coordinated regional operating plan was adopted by the water supply...
Applications of Spreadsheets in Water Resources
This paper describes two applications of the spreadsheet MULTIPLAN to water resources problems. Applications include statistical analysis of water resources data and design of a stormwater...
Water Quantity Management for a River Regulating Agency
A river reservoir operations model (RROM) was developed to assist the Hudson River-Black River Regulating District manage flows in the Upper Hudson River Basin. The purpose of the RROM...
Reliability of Urban Water Supply Reservoir System
Assessment of the reliability, or risk of failure, of water supply reservoirs is dependent on several factors including reservoir volume, probability of dam failure and drought inflows....
