Paperback. Condición: New. Print on Demand. This book presents a comprehensive analysis of the physical, chemical, and bacteriological characteristics of streams in the Great Smoky Mountains National Park during 1977-78. The author investigated the influence of elevation, geology, and land use history on water quality parameters like pH, nitrate concentration, and bacterial density. The findings suggest that elevation strongly affects water quality, with higher elevations exhibiting lower pH and higher nitrate concentrations. Notably, streams draining previously logged watersheds had significantly lower nitrate levels than those in unlogged areas. The book also highlights the importance of bedrock geology in shaping water quality, as streams flowing over different rock types exhibited distinct chemical compositions. These insights contribute to our understanding of natural water quality patterns in relatively undisturbed ecosystems and provide valuable information for managing and protecting water resources in the Great Smoky Mountains National Park.
