The relevance of the Mediterranean Region to colonial waterbird conservation The relevance of the Mediterranean Region to colonial waterbird conservation
The Mediterranean Sea is the largest partially enclosed sea in the world and provides habitat to more than 100 species of waterbirds from the Palearctic-North African-Middle Eastern regions. Even though the Mediterranean suffers from pollution, has little tidal influence, and is oligotrophic, more than half of the western Palearctic populations of numerous waterfowl species winter in the...

Water-use analysis program for the Neshaminy Creek basin, Bucks and Montgomery counties, Pennsylvania Water-use analysis program for the Neshaminy Creek basin, Bucks and Montgomery counties, Pennsylvania
A water-use analysis computer program was developed for the Neshaminy Creek Basin to assist in managing and allocating water resources in the basin. The program was developed for IBM-compatible personal computers. Basin analysis and the methodologies developed for the Neshaminy Creek Basin can be transferred to other watersheds. The development and structure of the water-use analysis...

Ground-water quality in the Calumet Region of northwestern Indiana and northeastern Illinois, June 1993 Ground-water quality in the Calumet Region of northwestern Indiana and northeastern Illinois, June 1993
Water samples were collected from 128 wells in a large industrial and urban area in northwestern Indiana and northeastern Illinois during June 1993. Samples were collected from wells completed in one of four geohydrologic units: surficial sand aquifer (Calumet aquifer), clay confining unit, confined sand aquifers, and a carbonate-bedrock aquifer (Silurian-Devonian aquifer). Samples were...

Water-quality assessment of the White River Basin, Indiana: Analysis of selected information on nutrients, 1980-92 Water-quality assessment of the White River Basin, Indiana: Analysis of selected information on nutrients, 1980-92
Water-quality data from 23 surfacewater-quality monitoring sites operated by the Indiana Department of Environmental Management and streamflow data from 11 U.S. Geological Survey streamflow-gaging stations in the White River Basin were analyzed to determine recent (1981 90 water years) water-quality conditions, trends, and river loads for ammonia, nitrate, total nitrogen, and total...

National water summary on wetland resources National water summary on wetland resources
This National Water Summary on Wetland Resources documents wetland resources in the United States. It presents an overview of the status of knowledge of wetlands at the present time-what they are, where they are found, why they are important, and the controversies surrounding them, with an emphasis on their hydrology. Wetland resources in each State, the District of Columbia (combined...

Study design and preliminary data analysis for a streambank fencing project in the Mill Creek Basin, Pennsylvania Study design and preliminary data analysis for a streambank fencing project in the Mill Creek Basin, Pennsylvania
The Pequea Creek and Mill Creek Basins within Lancaster and Chester Counties in Pennsylvania have been identified as areas needing control of nonpoint-source (NFS) pollution to improve water quality. The two basins are a total of approximately 200 square miles and are primarily underlain by carbonate bedrock. Land use is predominantly agriculture. The most common agricultural NFS...
