History Of Sedimentation And Contamination In Valley Mill Reservoir, Springfield, Missouri, Susan S. Licher
History Of Sedimentation And Contamination In Valley Mill Reservoir, Springfield, Missouri, Susan S. Licher
MSU Graduate Theses
The Valley Mill Reservoir (VMR) was constructed between 1851 and 1871 and drains an important recharge area of the drinking water watershed for Springfield, Missouri. Presently, management efforts to protect downstream water quality are aimed at using VMR as a non-point pollution and sedimentation basin since its watershed is planned for continued urban development. The morphometry of VMR is typical of most reservoirs with an elongated basin and the deepest point being near the dam. Sedimentation within the reservoir has created a delta formation with upstream wetlands and floodplains acting as part of the delta especially during the past. Little …
Channel Geomorphology And Restoration Guidelines For Springfield Plateau Streams, South Dry Sac Watershed, Southwest Missouri, John M. Horton
Channel Geomorphology And Restoration Guidelines For Springfield Plateau Streams, South Dry Sac Watershed, Southwest Missouri, John M. Horton
MSU Graduate Theses
Land-use change, both historical and present, has been a source of channel degradation within Ozark streams. This study examines the influence of land use on channel morphology within the South Dry Sac Watershed which drains 78.5 km2. The main objectives of this study are to: (1) perform a geomorphic assessment of stream channel and sediment characteristics; (2) evaluate the effects of watershed factors on channel morphology and dynamics; (3) quantify the geomorphic relationships for use in stream restoration projects in the Springfield Plateau area. Thirty-six reaches were surveyed and evaluated in the field for channel cross-sectional geometry, longitudinal profile, and …
Temporal Analysis Of Floodplain Deposition Using Urban Pollution Stratigraphy, Wilson Creek, Sw Missouri, Kathy A. Shade
Temporal Analysis Of Floodplain Deposition Using Urban Pollution Stratigraphy, Wilson Creek, Sw Missouri, Kathy A. Shade
MSU Graduate Theses
Alluvial sediments record both hydrologic changes and variations of sediment quality affecting watersheds. This study uses urban pollution signatures as temporal tracers to date alluvial deposits along Wilson Creek located within Wilson’s Creek National Battlefield Park in southwestern Missouri. The creek drains Springfield, the third largest city in the state, which was settled in 1833. This study has three main objectives: (1) review historical documents to develop a pollution history for the watershed; (2) determine if there is a correlation between heavy metal and phosphorus concentrations in sediment cores and the timing of release of those elements into the creek …
