Optimal Muskingum River Routing
The Muskingum method of river routing is well established and frequently used. An attempt is made to improve the method by optimal selection of the model parameters. The common linear...

Fate and Transport of Metals in a River System
A steady-state model was developed that describes the fate of metals in a shallow river system. Settling and resuspension of solids were defined through empirical equations relating a...

Simplified Methods to Predict the Fate of Metals in Rives
Heavy metal contamination of rivers is of increasing concern to society. To help predict the fate of metals in rivers, researchers have developed computer models to simulate speciation...

Impacts of Stormwater Runoff on Receiving Waters
A planning methodology to assess the impact of stormwater runoff on streams in Vermont is demonstrated. The methodology, which is based on a statistical representation of runoff and stream...

A Study of River Foaming and its Possible Causes
Foaming has been observed on uncontaminated upland streams draining watersheds having no human related development. Because water alone will not foam when agitated, the presence of these...

Significance of In-Stream Denitrification
In-stream denitrification rates were calculated using a simultaneous nitrogen and dissolved oxygen mass balancing technique. Anaerobic, laboratory, incubation of stream bottom samples...

Microcomputer Methods for Toxicants in Ground Waters and Rivers
This paper describes a program written for the IBM personal computers to assess the fate of toxicants in ground waters and in rivers. The algorithms in the program were selected from a...

Gains and Losses of Commingled Waters in a Stream
In a legal dispute in the State of Washington (Colville Confederated Tribes vs. Boyd Walton, Jr. , Farmer), it became necessary to determine the proportion of transmission losses sustained...

Institutional Constraints and Evaluation of Potential Management Strategies on the Colorado River System
Management of the Colorado River reservoir system is a complex problem influenced by a number of institutional constraints including interstate compact agreements, international treaties,...

Optimization of Irrigation Distribution System Operation
The initial phases of the Federal Central Arizona Project (CAP) are nearing completion and in the latter part of this year the long-awaited delivery of Colorado River water will become...

Hydrologic Impacts of Improved Irrigation Efficiencies
The Salt River drainage basin (Star Valley) is an agricultural watershed of 829 mi**2 (2150 km**2) in western Wyoming. Salt River stream flows were hydrologically analyzed and a comparison...

Appropriated Water Rights in Utah
The appropriated water rights system used in Utah is discussed. The historical background for establishing this allocation process is reviewed. The process of changing the location and...

Water Requirements of Mountain Meadow Vegetation
Measurements to define agricultural water consumption have been taken in the Green River Basin of Wyoming throughout the summers of 1983 and 1984. The weekly measurements included water...

Effect of Santa Rosa Lake on Ground Water Flow to the Pecos River, New Mexico
In 1980, Santa Rosa Dam began impounding water on the Pecos River about 7 miles (11 kilometers) north of Santa Rosa, New Mexico, to provide flood control and storage for irrigation. Santa...

Modeling Flow in an Ephemeral Stream Channel
A particularly distinguishing characteristic of ephemeral streamflow is the large role played by infiltration. Infiltration interacts in a complex way with channel flow to control the...

Innovative Management in a Period of Austerity: The Glamorgan Heritage Cost Experience in the U.K.
Restraint in UK economic growth gave rise to a new countryside management approach which was non-statutory, dependent upon voluntary agreements. In essence the land remains in private...

Fishery Mitigation in an Estuarine Environment
This paper summarizes the major features of the estuarine mitigation plan proposed by New York State Department of Transportation in conjunction with the interstate highway project known...

Regional Waterfront Planning Without a Superagency: Can Existing Agencies Fill the Gap?
As far back as 1966, the Regional Plan Association saw the potential for mixed use development of underutilized and vacant land along New Jersey's Hudson River Waterfront....

Investigations of Day-Night Distributional Changes of Striped Bass in Hudson River Interpier Areas
As part of a Hudson River fisheries study, investigations were made in an attempt to assess whether onshore-offshore movements could change the number of juvenile striped bass using interpier...

Importance of Underpier Areas in Lower Hudson River for Striped Bass
A stratified random sampling design was employed in which each of three sampling zones (New York, New Jersey and Upper Harbor underpier areas) were sampled once per month from February...
