Spatial Variability Of Nonpoint Source Yields In Ozark Highlands Watersheds Under Historical And Recent Land Use Conditions, Tyler J. Pursley
Spatial Variability Of Nonpoint Source Yields In Ozark Highlands Watersheds Under Historical And Recent Land Use Conditions, Tyler J. Pursley
MSU Graduate Theses
Many of the environmental problems facing communities today stem from historical as well as present land use disturbances related to agriculture, urbanization, and resource extraction. It is important to evaluate a range of land use and soil effects on nonpoint source (NPS) pollution to fully understand land use-water quality relationships. The Ozark Highlands region has undergone significant phases of land use change throughout its settlement history and is actively developing today (2020). This study used nonpoint nitrogen (TN), phosphorus (TP), and sediment (TSS) yields predicted by the US EPA’s Spreadsheet Tool for Estimating Pollutant Loads (STEPL) model to evaluate human …
Geomorphic Effects Of Engineered Log Structures And Response To A Catastrophic Flood Event In A Missouri Ozarks River, Joseph S. Nash
Geomorphic Effects Of Engineered Log Structures And Response To A Catastrophic Flood Event In A Missouri Ozarks River, Joseph S. Nash
MSU Graduate Theses
Engineered log structures (ELSs) composed of local tree logs have been installed in river channels throughout the Pacific Northwest as a restoration technique. However, ELSs have not been tested for use in the Ozark Highlands until recently. In October 2016 the U.S. Forest Service installed four ELSs to stabilize banks along the North Fork of the White River in Ozark County, Missouri. The purpose here is to report on monitoring studies of pre- and post-restoration channel conditions and to assess geomorphic responses to floods. Over a ten-day period in April 2017 there were two bankfull floods, and on April 30, …
