Progress of environmental studies in coal mining areas of western Pennsylvania and central West Virginia Progress of environmental studies in coal mining areas of western Pennsylvania and central West Virginia

Two studies related to the regional environmental effects of coal mining in the Appalachian Plateau were conducted in 1998 as part of the National Water‐Quality Assessment program of the U.S. Geological Survey. The study area of about 20,000 square miles included parts of the Allegheny and Monongahela River basins in the north and the Kanawha River basin in the south. Water in domestic...

Tracing sediment dispersal on nourished beaches: Two case studies Tracing sediment dispersal on nourished beaches: Two case studies

The event- to decade-scale patterns of sediment dispersal on two artificially nourished beaches have been mapped using a combination of geophysical surveys, closely-spaced vibracores, and repeated beach profiles. At both Wrightsville Beach, NC and Folly Island, SC the sediment used for beach nourishment is macroscopically distinct from native sediment and can be used to identify sediment...

A weighted least-squares approach to temporal NDVI smoothing A weighted least-squares approach to temporal NDVI smoothing

Satellite imagery provides a unique vantage point for observing seasonal dynamics of the landscape that have implications for global change issues. An objective evaluation of surface conditions may be performed using the normalized difference vegetation index (NDVI) derived from National Oceanic and Atmospheric Administration advanced very high resolution radiometer data. NDVI data are...
