Fish Wintering in the Sagavanirktok Delta, Alaska
Anadromous fish of the Alaskan Beaufort Sea overwinter for eight to nine months in isolated pools of coastal rivers where water remains unfrozen through the winter. Available overwintering...
Patuxent River Policy Plan
Degradation of the Patuxent River, a major tributary of the Chesapeake Bay, prompted the Maryland General Assembly to establish the Patuxent River Commission and require preparation of...
Nisqually River Management Plan
The Nisqually River is unique in Washington State, if not the nation, in having as its headwaters a glacier within a national park, and its estuary within a national wildlife refuge. The...
Special Canada-U.S. Workshop/Panel
Panel members with hands-on-experience in estuarine planning and management are drawn from British Columbia, Washington, Oregon and California. They highlight those factors which they...
Changing Waterfront Uses on the River Clyde, Scotland: A Preliminary Survey
The River Clyde in Scotland was renowned for its shipbuilding and shipping facilities. However, dislocations combined with government policy have forced since the early 1960's...
An Innovative Solution to the Difficult Coastal Zone Management Problem of Dredge Material Disposal
The New York Power Authority is constructing a 300 km predominantly double circuit 345kV transmission facility through southeastern New York State. A key element in this project is the...
Little River: An Investigation of Coastal Environment
Little River is located about 6. 5 kilometres north of Comox on the east side of Vancouver Island. The last major flood in February of 1983 resulted in the river breaking through the beach...
Cogenerating Columbia River Salmon and Hydropower
In recent years a number of regional institutional arrangements have been consumated which have potential for reducing overfishing of Columbia River chinook stocks. In the Pacific Northwest...
Jean Lafitte's Real Legacy and Treasure
The Barataria Estuarine System is part of the Mississippi River which swept back and forth across Louisiana for thousands of years. Barataria Bay no longer receives the enrichment of the...
Optimization: An Emerging Technology
The technology of formal, numerical structural optimization is neither mysterious nor complex. Software programs are now available for use by engineers who do not have detailed knowledge...
Bival System for Downstream Control
The BIVAL system of canal regulation guarantees that the maximum discharge can be delivered at any time, as for downstream control systems and, moreover, it minimizes the canal dyking...
The Urbanization of the Salt River Project
The Salt River Project (SRP) is one of the nation's oldest and most successful agricultural reclamation projects. Formed in 1902, its initial function was to manage the surface...
Riprap Stability on Channel Slide Slopes
The stability of riprap placed on a sloping bank is decreased because one component of gravity tends to displace the rock down the slope. Results of riprap stability tests on sloping banks...
Estimating Average Velocity in Cobble-Bed Channels
A data set obtained from natural channels having D//5//0 less than 64 mm and d/D//5//0 in the range of 3 to 20 is used as a basis for testing equations proposed by Limerinos, Thompson...
Satellites Monitor Eutrophication of Estuaries
In a study on eutrophication of estuaries, NOAA/AVHRR satellite data have been analyzed for the Changjiang River plume and the adjacent coastal areas. The different regimes identified...
A Mathematical Model for River Ice
Several computer models for simulating river ice conditions have been developed (Petryk, 1986). All of these models simulate frazil ice production, and the progression, erosion and melting...
Open Channel Flow Resistance in Horseshoe Conduits
An experimental study of open channel flow resistance in horseshoe-shaped conduits is reported. The friction factor is shown to increase approximately 20 percent in comparison to values...
Imbrication of Tabular Boulders
Analysis of moments on tabular boulders projecting into a uniform stream indicates that a tabular boulder dipping downstream is unstable and can be overturned by velocities expected during...
Simulation of Sediment Transport in Coastal Water
The sediment-contaminant transport code, FETRA, coupled with the hydrodynamic model, CAFE-I; and the wave refraction model, L03D; were applied to Pacific coastal water. The FETRA model...
Coupled Implicit Simulation of Mobile-Bed Rivers
Numerical and physical deficiencies in existing computational codes for simulation of bed evolution in mobile-bed rivers have led the authors to propose a new approach. The new method...
