Toxic Contaminant Uptake in Dredged Sediment Marshes
Dredged sediments from the proposed enlargement of the Lower Mississippi River from Venice, Louisiana to the Gulf of Mexico would be primarily utilized to create up to 28,000 hectares...
Reservoir Management for Improved Water Quality
In 1981, the City of Akron, Ohio initiated a multidisciplinary study to develop a reservoir management plan for its 3 reservoirs in the upper Cuyahoga River basin. The City sought possible...
Nebraska's Shrinking Platte River Channel: Biological Aspects and Implications
Since the completion of major water projects along Nebraska's Platte River system in 1941, vegetative encroachment and channel narrowing have substantially altered the central...
Nebraska's Shrinking Platte River Channel: Hydrologic Aspects and Implications
Biologists have proposed two hypotheses to explain recent channel narrowing and vegetative growth in flood plain habitat areas along the Platte River in Nebraska. One group contends, without...
Hazardous Waste Landfill: Some Lessons from New Jersey
There are four key elements in a secure, hazardous waste landfill: a bottom liner; a leachate collection system; a cover; and the natural hydrogeologic setting. Each of these elements...
