Stream Bank And Bar Erosion Contributions And Land Use Influence On Suspended Sediment Loads In Two Ozark Watersheds, Southeast Missouri, Kayla Ann Coonen
Stream Bank And Bar Erosion Contributions And Land Use Influence On Suspended Sediment Loads In Two Ozark Watersheds, Southeast Missouri, Kayla Ann Coonen
MSU Graduate Theses
In-channel sources and storages of fine-sediment such as in banks and bars can influence sediment loads and overall geomorphic activity in stream systems. However, in-channel processes and effects on sediment load are rarely quantified in geomorphic or water quality studies. This study uses a sediment budget approach to assess the influence of bank erosion and bar deposition on fine sediment loads in Mineral Fork (491 km2) and Mill Creek (133 km2) watersheds located in the Ozark Highlands in Washington County, Missouri. These watersheds were disturbed by historical lead and barite mining which included the construction of …
Geomorphic Effects Of Logging Railbeds On An Ozarks Headwater Stream, Mark Twain National Forest, Missouri, Nickolas S. Bradley
Geomorphic Effects Of Logging Railbeds On An Ozarks Headwater Stream, Mark Twain National Forest, Missouri, Nickolas S. Bradley
MSU Graduate Theses
Geomorphic characteristics of headwater streams draining the Missouri Ozarks have not been studied as much as larger rivers in the region. Further, while the effects of historical logging on channel form and sediment supply have been identified, no studies have investigated the effects of logging tramways constructed along Ozark headwater rivers. This study examines the geomorphic characteristics and channel disturbances of Tram Hollow (1.67 km2) within the Mark Twain National Forest in the Ozark Highlands. The purpose of this study is to classify and quantify natural and disturbed channel morphology in Tram Hollow which has been affected by …
Spatial Distribution And Geomorphic Factors Of Lead Contamination On Floodplains Affected By Historical Mining, Big Rover, S.E. Missouri, David Bower Huggins
Spatial Distribution And Geomorphic Factors Of Lead Contamination On Floodplains Affected By Historical Mining, Big Rover, S.E. Missouri, David Bower Huggins
MSU Graduate Theses
Historical mining in the Old Lead Belt resulted in lead (Pb) contamination of floodplain soils for over 170 km along the Big River in southeastern Missouri. The overall pattern of contamination are understood. However, Pb distribution across floodplain surfaces has not been investigated at the scale needed for site-level remediation planning. The goal of this project is to examine spatial distribution of Pb with more detail and identify the role of geomorphic processes. Predictive models are needed to evaluate factors affecting Pb distribution such as elevation, distance from the channel, and geochemistry. This study evaluates Pb distribution at three ~1km …
