The Role of Local Government in Water Quality Management
To meet the challenge of providing safe drinking water at a reasonable cost, local governments, together with water utilities, must do more than merely fund the implementation of state...
Conjunctive Water Use Planning
The phase 'conjunctive use' refers to the integrated management of various water resources within a river basin or other geographic region. The objectives of...
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...
An Optimization Model for Use in Analysis and Design of Wastewater Treatment Systems
The objective of present wastewater treatment plant design is to provide a cost effective processing system for a given waste-water. Generally each of the unit processes is designed to...
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...
Flow and Sediment Transport in Curved Channels with Nonuniform Bed Material
Described is a scheme for controlling the exchange of grain sizes between bed and bed load in a curved alluvial channel. The scheme is an integral part of a model for simulating spatial...
A New Technique for Measuring Fine Sediment Accumulation in Gravel Bed Streams
The collection and analysis of bed material samples has been a standard practice for determining the quantity of fine sediments (less than 3. 4 mm diameter) in stream gravels. However,...
Sediment Intrusion into the Substrate of Gravel Bed Streams
A physically-based model was developed to simulate the intrusion of fine sediments into stream gravel substrates and its effects on intragravel flow. The model is capable of simulating...
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...
Automated Control for Central Arizona Project Distribution Systems
Computer based automatic control for three extensive open channel water distribution systems is described. Radio telemetry allows a central computer to execute control logic at individual...
Geohydrologic Considerations in Ground Water Modeling
Ground water modeling is an effective engineering and management tool for evaluating complex hydrogeologic situations in a cost effective manner. Objectives of a particular study dictate...
North American Weather Modification Organizations
The objectives and purposes of most professional, technical and institutional organizations made up of people interested in weather modification as a tool in North American water resources...
Comparison of Minimum Instream Flow Needs
A sound determination of Instream Flow requirements is facilitated by the use of a physical habitat versus streamflow relationship and the analysis of instream flow benefits produced when...
Instream Flow Needs to Protect Fishery Resources
Numerous methods have been developed over the past several decades to assess the effects of flow regulation on fishery resources and to provide a basis for the determination of suitable...
Benefit-Cost Evaluation of Minimum Instream Flows
In many cases, determinations of minimum desirable instream flows (MIF) are made without full consideration of economic costs and benefits. Benefits are frequently quantified in nonmonetary...
Queensland, Australia - River Diversion Schemes
The east coast of the State of Queensland has high or very high annual rainfall which declines rapidly with distance inland. The area west of the Great Dividing Range, which parallels...
Garrison Diversion Unit?An Example of United States-Canada Cooperative Investigation
Canada and United States have cooperated in the investigation of disputed international waters on numerous occasions. The study of the Garrison Diversion unit is an example of an exhaustive...
The Changing Objectives of Garrison Diversion Unit
Construction of the 101,000-hectare initial stage Garrison Diversion Unit was authorized in August 1965 as a feature of the Pick-Sloan Missouri Basin Program for irrigation and other purposes....
Changes in Management: International Great Lakes
Unprecedented changes in the binational management of the Great Lakes are underway. Problems and programs to solve them increasingly are being considered on an ecosystem (comprehensive,...
The Inquiry on Canadian Federal Water Policy
The paper summarizes the results of an inquiry undertaken into Canadian Federal water policy by three persons appointed by the Canadian Federal Minister of the Environment. The investigation...
