Modified QUAL2E Modeling of a Stream Acutely Impacted by Photosynthesis and Respiration
The QUAL2E model was modified to account for time variable headwater conditions and the photosynthesis and respiration of attached aquatic plants. With these modifications, a stream that...
Bodkin Island Wetland Restoration Project Design
Bodkin Island in the Chesapeake Bay will be increased by 2 hectares through placement of dredged material to create nesting and brood habitat for black ducks. The enlarged island will...
Rethinking the Competitive Bid
Concern that the U.S. construction industry is losing its competitive edge is nothing new. Ironically, the problem is not so much rooted in foreign technical expertise as it is in our...
A Two-Dimensional Surface Drift Model for River Ice
A two-dimensional surface drift model for river ice with low ice discharge conditions is presented. The model is applied to the Grass Island Pool area of the Niagara River and compared...
Radar Monitoring of Ice on the Upper Niagara River
A standard marine radar was used during the winter of 1987-88 to evaluate its potential to monitor the presence and movement of ice in the Grass Island Pool area of the upper Niagara River....
The Reclamation Program for the Yucca Mountain Project
The U. S. Department of Energy (DOE) is required by law and other regulatory requirements to reclaim disturbances created by site characterization activities at Yucca Mountain. Because...
Compaq Center East Water Management Plan
This Water Management Plan attempts to balance the many goals which were established in the Master Plan. Major areas of natural vegetation have been preserved. Stormwater quality pond/wetland...
Aerial Videotape Mapping of Coastal Geomorphic Changes
An aerial geomorphic mapping system was developed to examine the spatial and temporal variability in the coastal geomorphology of Louisiana. Between 1984 and 1990 eleven sequential annual...
Sonar Mapping of Giant Kelp Density and Distribution
The methods of estimating the density and distribution of giant kelp, Macrocystic pyrifera, and substrate type, using side-scanning and down-looking sonar are described. These techniques...
The Acqisition of Remotely Sensed Sargassum Information on Daya Bay
The nuclear power plant on Daya Bay is the largest nuclear power plant under construction in China. In order to obtain reliable data about the possibility of blocking of the water intake...
Roadside Associated Disturbance on Coastal Dunes
Park Road 100 extends through the developed southernmost 8 km of South Padre Island and continues northward for 11.5 km through the Secondary Dunes and Vegetated Flats (SDVF) zone of the...
Success of Dune Restoration After Removal of UXO
The discovery of unexploded ordnance (UXO) at South Beach, a popular recreational beach on Martha's Vineyard island in Massachusetts, necessitated that the area be declared...
San Diego Bay Eeelgrass Planting and Mitigation
This paper will discuss the Navy's efforts to mitigate for the loss of eelgrass and creation of an eelgrass bank to compensate for possible future losses in San Diego Bay....
Restoration of Coastal Dune Systems in Southern California State Parks
Coastal dune systems in southern California possess little of their historical and biological characteristics. If not completely extirpated by development, then the loss of native plants...
Global Climate Change: USFWS Coastal Research
Scenarios of global climate change are still ambiguous; however, increasing sea level and atmospheric carbon dioxide (CO2) concentrations seem certain,...
Resilience of Seacoast Bluestem Barrier Island Communities
Natural disturbance is an important force in population and community dynamics and barrier islands are paradigms of disturbance dominated ecosystems. They are formed, shaped, and moved...
The Effect of Beach Vegetation on Aeolian Sand Transport
The effect of coastal vegetation on aeolian sand transport is examined through consideration of the governing aerodynamic processes. Local scale processes without the effect of ground...
Practical Use of Plants for Water Purification
Problems with contaminated wastewater in USA, Eastern Europe, and developing countries are outlined. Botanical sewage purification for purifying human, animal, and industrial sewage is...
Improving the Assessment of Instream Flow Needs for Fish Populations
Instream flow requirements are one of the most frequent and most costly environmental issues that must be addressed in developing hydroelectric projects. Existing assessment methods for...
Twin Falls Mitigation Plan: Long Term Monitoring of Fish Populations
A fishery monitoring and enhancement plan has been worked out for the Twin Falls Hydroelectric Project which diverts water from a one mile reach of the South Fork Snoqualmie River in Washington...
