Mining And Residential Development Interact To Produce Highly Impaired Stream Conditions In An Intensively Mined Appalachian Watershed, Eric Richard Merriam
Mining And Residential Development Interact To Produce Highly Impaired Stream Conditions In An Intensively Mined Appalachian Watershed, Eric Richard Merriam
Graduate Theses, Dissertations, and Problem Reports
Large scale surface mining in southern West Virginia causes significant alteration of headwater stream networks. It is unclear, however, the extent to which mining interacts with other stressors to determine physical, chemical, and biological conditions in aquatic systems downstream. Through a watershed scale assessment of Pigeon Creek, the specific objectives of this study were to: (1) quantify the direct and interactive effects of mining and residential development on in-stream conditions; and (2) identify landscape thresholds above which biological impairment occurs. Our results indicate high levels of impairment to habitat, water quality, and benthic invertebrate communities within this watershed. Statistical analyses …
Ecological Responses Of Streams To Anthropogenic Stressors, And Watershed Cause-Effect Modeling In The Mid-Atlantic Highlands Region Of The United States, Yushun Chen
Graduate Theses, Dissertations, and Problem Reports
Urban sprawl and related habitat disturbance and acidic deposition are major anthropogenic stressors in the Mid-Atlantic Highlands region of the United States. Little information is available about the impacts of these stressors and cause-effect relationships between these watershed stressors and stream biotic/abiotic conditions in this region. A 10-year study (1997-2006) in the Lost River watershed and a 6-year study (2002-2007) in a South Branch Potomac River watershed were conducted to assess the impacts of Corridor H highway construction on stream biotic and abiotic conditions. Also, a three-decade study (1980-2006) using data from 5 wet deposition stations and 21 major stream …
