Appropriate Technology in Infrastructure Development and Management
Infrastructure management principles apply to appropriate technologies used for hydraulic structures. However, some of the principles are more culturally sensitive than others, mainly...
Incipient Motion Criteria Defining Safe Zones for Salmon Spawning Habitat
Approximately 70% of the City of Seattle's water supply is drawn from the Cedar River. Between 200,000 and 400,000 sockeye salmon spawn annually in this partially dewatered...
Experimental Model Study of Over and Under Baffles
A hydraulic model study of a chlorine mixing channel was conducted at the Hydraulic Research Laboratory of the City of Los Angeles. An arrangement of over-under baffles was used to facilitate...
Application of a 2-D Water Quality Model (BETTER) to Manage Effects of Low Flow and Wastewater Effluents in Cheatham Lake, Tennessee
Applications of BETTER, a 2-D reservoir water quality model, have been made by the Nashville District Corps of Engineers (Corps) and by the Nashville Metropolitan Water and Sewerage Services...
A Review of Modeling and Analysis Approaches for Optimization of Reservoir System Operations
Numerous mathematical models have been developed for sizing reservoir storage capacities and establishing operating policies during project planning, for reevaluating the operating policies...
Application of a Generalized Risk Dynamic Model to a Spillway Design Flood
Risk analysis can provide a logical basis for selecting the optimal design capacity of a flow conveyance hydraulic structure for the least total cost or specified non-exceeding risk levels....
Dam Removal Methods, Elwha River, Washington
Preparation of an Environmental Impact Statement (FERC, 1991) for licence applications for the Elwha and Glines Canyon hydroelectric projects on the Elwha River, Washington, included evaluation...
Proposed Methodology to Update Embayment Sedimentation Data for TVA Reservoirs
The purpose of this paper is to evaluate the accuracy and usefulness of bathymetric data resulting from routine fisheries and aquatic biology hydroacoustic surveys in TVA reservoirs for...
Improved Intake Design for Downstream Migrating Fish at Hydropower Plants
Fish guidance efficiency of screens is a function of the submergence of a hydropower intake. The submergence of an intake can be reduced through the use of intake extensions or guides...
Seawater Delivery for Use in Aquaculture Development
Seawater is used extensively in industrial and aquacultural developments world wide, and aquaculture in particular requires large quantities of seawater. Development and design of facilities...
McClure Park: A Multi-Purpose Off-Stream Storage Facility for Tulsa, Oklahoma
The City of Tulsa is in the process of implementing a flood control plan for the 61 square-mile (158 km2) Mingo Creek watershed. The federally-assisted...
Geographic Information Systems in Water Resources Management
The management of surface and ground water resources within Southern California is increasingly difficult. As population expands, municipal demands for water are increasing. At the same...
A Knowledge-Based System for the Environmental Design of Waterways (ENDOW)
Knowledge-based software systems accept problem descriptions from users and apply logic in order to generate a solution or solution set. These systems function over very narrow problem...
A Knowledge Based System for Design of Localized Mechanical Mixing Systems
Knowledge-based systems, frequently referred to as expert systems, have been used in a variety of computer-based design applications. They are particularly suited to design processes where...
Low Flow Index and Hydrogeological Characteristics
This work is set within a framework of research on drought phenomena, causes and effects, and the methods to fight the harmful effects of droughts in the agricultural, municipal and industrial...
Probabilistic Aspects of Hydroproject Maintenance
A survey of operation and maintenance personnel in the hydraulic structures sector was conducted to learn about the present maintenance approach and the perception of the probabilistic...
Diffuser Design for Water Quality-Based Toxics Control
U.S. Environmental Protection Agency regulations require that the discharge of toxic pollutants to the waters of the United States be controlled. These regulatory requirements have made...
Conventional Storm Drainage Which Recharges the Groundwater
Since the demand for water is on the rise, more resourceful means of retaining and controlling the release of stormwater is needed. This retained stormwater may then be used for aesthetic...
Routing for Lake and Tidal Canal Drainage System
A routing method is presented for lake and tidal canal interconnected drainage system in coastal urban areas. Combing reservoir routing, channel routing, and discharge computation of the...
Management of Water Resources Distribution in Iran
On the basis of 45th principle of the Iranian Constitution, seawater as well as river waters, streams and any other natural course, whether surface or underground, also floods, wastewaters,...
