Historical Land Use Influence On Fine-Grained Sedimentation In Channel And Floodplain Deposits In A Forested Missouri Ozark Watershed, Katy Nicole Reminga Aug 2019

Historical Land Use Influence On Fine-Grained Sedimentation In Channel And Floodplain Deposits In A Forested Missouri Ozark Watershed, Katy Nicole Reminga

MSU Graduate Theses

Hydrologic disturbances due to land use and climate effects can disrupt river form and increase sediment transport. Ozark streams have been experiencing the effects of accelerated channel erosion on coarse sediment delivery and gravel bar deposition since the onset of early European settlement in the late 1800’s. Little attention has focused on understanding the fate of fine-grained sediment released by upland soil and headwater channel erosion and the potential for storage as legacy deposits on floodplains. Legacy deposits are attributed to human disturbances as the result of land clearing and agriculture that increase runoff, soil erosion, flooding, and sediment supply …


Geomorphic Disturbance And Anthropogenic Modifications In Big Barren Creek, Mark Twain National Forest, Southeast Missouri, Rachael A. Bradley Aug 2017

Geomorphic Disturbance And Anthropogenic Modifications In Big Barren Creek, Mark Twain National Forest, Southeast Missouri, Rachael A. Bradley

MSU Graduate Theses

This study investigates the influence of human disturbance on channel conditions in Big Barren Creek. The Big Barren watershed drains 191 km2 of the Ozark Highlands in southeast Missouri. Several segments of the creek have been channelized by levee construction and gravel mining. Approximately 27.2 km of the main stem of Barren Creek were assessed for 13 photo-years ranging from 1939 to 2014. Geomorphic classifications using channel conditions in aerial photographs and field observations were used to evaluate patterns of disturbance. While 52% of the creek is managed by private landowners, 81% of disturbed length occurs on private lands. Further, …


Geomorphic Effects Of Logging Railbeds On An Ozarks Headwater Stream, Mark Twain National Forest, Missouri, Nickolas S. Bradley May 2017

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 …
