Geomorphology And Chronology Of Sand Stringer Deposition Beyond The Ice Margin: Southeastern Minnesota And Western Wisconsin, Usa, Richard J. Mataitis
Geomorphology And Chronology Of Sand Stringer Deposition Beyond The Ice Margin: Southeastern Minnesota And Western Wisconsin, Usa, Richard J. Mataitis
All Graduate Theses, Dissertations, and Other Capstone Projects
The purpose of this Master’s thesis is to investigate linear, aeolian deposits termed “sand stringers” located within western Wisconsin and southeastern Minnesota. Previous research has investigated their spatial distribution, and to a minor extent, their composition and absolute age. However, further sedimentological and absolute age data are needed from a greater distribution of sand stringers to understand their formation and depositional chronology. To build on previous research we 1) remotely mapped the spatial distribution and orientation of sand stringers in western Wisconsin and southeastern Minnesota, 2) collected absolute age data using optically stimulated luminescence (OSL) from four stringers in western …
Mass Wasting Investigation And Assessment In The Midwest: Case Study Of The Minnesota River Valley, New Ulm To St. Peter, Minnesota, Usa, Melissa Kohout
Mass Wasting Investigation And Assessment In The Midwest: Case Study Of The Minnesota River Valley, New Ulm To St. Peter, Minnesota, Usa, Melissa Kohout

Many mass- wasting studies have been conducted worldwide, however, investigations have focused in mountainous or coastal regions. This has proven problematic in areas lacking those features yet are experiencing mass wasting. Several anthropogenic risks, economic loss, and environmental issues are associated with mass wasting such as destruction of property, loss of life, and sediment pollution. The midwestern USA, is generally considered a low relief region, therefore limited data exist for mass wasting occurrence. Within the last decade, however, several events have occurred across Minnesota with little understanding of the ongoing hillslope processes leading to failure. The Minnesota River valley is …
Assessing Historical Planform Channel Change In An Altered Watershed With Quantification Of Error And Uncertainty Present In A Gis/Aerial Photography-Based Analysis; Case Study: Minnesota River, Minnesota, Usa., Devon Libby
All Graduate Theses, Dissertations, and Other Capstone Projects
Little is known about the historic planform channel change of the Minnesota River of south-central Minnesota, USA. This is despite research that demonstrates anthropogenic activities have altered the Minnesota River Basin's hydrology, land use, and climate. In addition, the threat of invasive carp infestation requires an understanding of Minnesota River planform change to assess mitigation strategies. This thesis focuses on the lower Minnesota River (LMR) by measuring planform channel change (lateral channel migration, width, and sinuosity) from 1937 to 2013. Analysis is conducted by utilizing remote/GIS analysis of historic aerial photographs. A secondary focus addresses and quantifies the inherent/introduced error/uncertainly …
