Tidal Mass Exchange Between a Submersed Aquatic Vegetation Bed and the Main Channel of the Potomac River
Tidal mass exchange between a submersed aquatic vegetation (SAV) bed and the main channel of the Potomac River was investigated. Water levels were recorded at 5 minute intervals from August...
Effects of Fine Sediment Intrusion on Spawning Gravel in Southeast Alaska
The supply of sediment to forest streams in Southeastern Alaska is related to the inherent instabilities of landforms, stream channels and the effects of logging practices. Debris avalanches,...
Physical Model of a Floating Trash Boom to Control Aquatic Weeds at the TVA Widows Creek Fossil Plant
The Tennessee Valley Authority (TVA) Widows Creek Fossil Plant seasonally encounters adverse accumulations of aquatic weeds at the intakes of the condenser cooling water pumps. To reduce...
Rainfall-Reaeration Effects
The effect of rainfall intensity on reaeration has not been adequately reported in the literature. It is clear that rainfall causes surface turbulence and increases reaeration, and a significant...
Predicting Effects of Global Climate Change on Reservoir Water Quality and Fish Habitat
This paper demonstrates the use of general circulation models (GCMs) for assessing global climate change effects on reservoir water quality and illustrates that general conclusions about...
Application of a Water Budget for Instream Flows
A portion of a water supply reservoir can be dedicated to supplying instream flows. This subreservoir is operated to provide instream fish habitat below the reservoir when releases to...
Watershed Condition and Riparian Health: Linkages
This paper discusses linkages between riparian areas and their contributing watersheds and how using this knowledge will enhance overall watershed management success. The paper presents...
Sacramento-San Joaquin Delta The Key to Water Transfer
The Delta is a key feature in California's water resources picture. This ecologically sensitive area is currently experiencing adverse effects from water diversions and needed...
Soil-Moisture Flux Studies on the Nevada Test Site A Review of Results and Techniques
Over the last 20 years, numerous studies of soil-moisture flux and/or ground-water recharge have been conducted on the U.S. Department of Energy's (DOE) Nevada Test Site (NTS)...
Major Sedimentation Issues for the USGS
Historically, sediment information has been used primarily in planning for engineering structures that were designed to meet a single or a very limited number of objectives. Today most...
Sediment and Aquatic Habitat Associations in River Systems
This paper results from the Task Committee's effort to summarize knowledge linking sediment transport and aquatic ecology. This paper presents one element of this work: the...
Sediment Transport, Hydraulic Retention Devices, and Aquatic Habitat in Sand-Bed Channels
Streams and rivers of all sizes and in all parts of the United States flow on sand-bed channels. Scour, Transport, and deposition of sediments particles are natural processes in these...
Sediment Transport and Aquatic Habitat in Gravel-Bed Rivers
Gravel-bed rivers experience dymanic conditions of flow and sediment transport. Long periods of bed stability are interrupted by shorter periods of bed mobility when major changes and...
Management of Fisheries in the State of Rio De Janeiro, Brazil
To improve the interdisciplinary knowledge and to subdivide the problem in bio-ecological sectors, international committees recommend the development of integrated evaluation groups. On...
A Multivariate Analysis of Stillwater Lakes, Nevada
Stillwater Lakes located in western Nevada has been experiencing an astounding number of fish and waterfowl deaths since August 1986. This problem is explored through a multivariate statistical...
Behavior of Total Zinc in the Similkameen River
Multiple linear regression analysis was used to: develop equations that summarize the relationship between total zinc and a set of water quality characteristics measured in the Similkameen...
Aquatic Weed Control by Grass Carp in Cool Water
Diploid grass carp have significantly controlled problem aquatic vegetation during a 3-year study in a northern Colorado irrigation canal where water temperatures ranged from 0 to 25?C....
Conflict Resolution in Regional Water Management
The experience with environmental dispute resolution (EDR) at South Florida Water Management has been largely one of changing the operating premises regarding the agency's...
Intrusion of Turbid Water into a Two-Layer Stratified Environment
The horizontal intrusion of a turbid water with some intermediate density spreading on the interface of a two-layered homogeneous body of water is investigated. The study is directed towards...
Flushing Flow Analysis Concepts
Many environmentally oriented groups who oppose water resources projects, have conceived various types of flow requirements to supposedly meet a variety of biological purposes in rivers....
