Soil Chemistry Characterization Of Acid Sensitive Watersheds In The Great Smoky Mountains National Park, Mary Ann Elizabeth Grell
Soil Chemistry Characterization Of Acid Sensitive Watersheds In The Great Smoky Mountains National Park, Mary Ann Elizabeth Grell
Masters Theses
Atmospheric acidic deposition has negatively impacted many Appalachian watersheds in the eastern United States and soils play a key role in the biogeochemical processes that govern the fate and transport of the acidic pollutants. Thus, the collection of soil chemistry data, a previously lacking component, is essential to understand the soil processes related to the retention or release of basic and acidic ions and is imperative for the prediction of ecosystem recovery. Soil chemical properties related to acidification were characterized for 25 sites within eight acid-sensitive watersheds located in the Great Smoky Mountains National Park (GRSM). Relationships were identified by …
Long-Term Acid Deposition Effects On Soil And Water Chemistry In The Noland Divide Watershed, Great Smoky Mountains National Park, Usa, Meijun Cai
Doctoral Dissertations
Impacts of long-term acid deposition on soil and water chemistry are of particular concern in the Great Smoky Mountains National Park (GRSM), receiving some of the highest acid deposition rates in the eastern United States and limited by inadequate acid buffering capacity. In the GRSM, the Noland Divide watershed (NDW) has been monitored since 1991 for water chemistries of precipitation, throughfall, soil, and stream. The impacts of long-term acidic deposition on stream water quality in the NDW were investigated through: 1) development of an ion input-output budget; 2) analysis of trends and seasonal patterns for major ions; 3) comparison of …
