Quantifying The Effectiveness Of Cedar Revetment In Mitigating Bank Erosion In Riceford Creek, Minnesota, Talia A. Klein
Quantifying The Effectiveness Of Cedar Revetment In Mitigating Bank Erosion In Riceford Creek, Minnesota, Talia A. Klein
MSU Graduate Theses
Southeastern Minnesota has incised streams that are susceptible to bank erosion. Previously, efforts have been made to identify sections of Riceford Creek that have high erosion susceptibility using the Bank Erosion Hazard Index (BEHI). Locally harvested cedars were then used as a revetment strategy to mitigate erosion of the stream banks prioritized by the BEHI analysis. This study aims to 1) determine if cedar revetment effectively mitigates bank erosion in Riceford Creek and 2) determine if the BEHI method is an effective way of quantifying erosion hazard in Riceford Creek. This study focuses on two sections in Riceford Creek where …
Historical Land Use Influence On Fine-Grained Sedimentation In Channel And Floodplain Deposits In A Forested Missouri Ozark Watershed, Katy Nicole Reminga
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 …
Stream Channel Morphology And Riparian Forest Response To A 500-Year Flood In The Missouri Ozarks, Joshua William Hess
Stream Channel Morphology And Riparian Forest Response To A 500-Year Flood In The Missouri Ozarks, Joshua William Hess
MSU Graduate Theses
Climate change has increased the frequency of large floods in rivers draining the Ozark Highlands resulting in higher rates of channel sedimentation, bank erosion, and damage to infrastructure. This study assesses the effects of a large flood (>500-year RI) during April-May 2017 on riparian forests along six tributary streams in the North Fork of the White River watershed, Missouri. High-resolution (<8 >cm) Unmanned Aerial Vehicle (UAV) imagery collected after the flood was used to identify riparian forest flood damage. Measurements of riparian forest flood damage calculated from the UAV imagery were verified through field surveys of damaged riparian trees. …
Geomorphic Response To Catastrophic Flooding In A Karst Mountain Stream System, Brighton-Blue Hole Watershed, Southwest Jamaica, Sarah M. Letarte
Geomorphic Response To Catastrophic Flooding In A Karst Mountain Stream System, Brighton-Blue Hole Watershed, Southwest Jamaica, Sarah M. Letarte
MSU Graduate Theses
The geomorphic effects of flooding are poorly understood in the karst, mountain watersheds along the southwest coast of Jamaica. This study describes the flow path and geomorphic response of an extreme flood event in the Brighton-Blue Hole watershed (BBHW) (6.8 km2) near Belmont, Westmoreland, Jamaica. A tropical depression classified as a >100-year rainfall event produced 32 inches of rain in a 24 hour period in Westmoreland on June 12, 1979. For this study, geomorphic indicators of flood disturbance in BBHW were assessed in 2017-18, finding that channel system responded to the flood with channel incision, debris flows, and …
Sediment Transport And Channel Morphology Of A Natural And A Leveed Alluvial River, Bo Wang
Sediment Transport And Channel Morphology Of A Natural And A Leveed Alluvial River, Bo Wang
LSU Master's Theses
Alluvial rivers are shaped by interactions of flow and sediment transport. Their lower reaches to the world’s oceans are highly dynamic, often presenting engineering and management challenges. This thesis research aimed to investigate channel dynamics and sediment transport in a natural river and a highly engineered river in South Louisiana, in order to gain much-needed science information for helping develop sustainable practices in river engineering, sediment management, and coastal restoration and protection. Especially, the thesis research examined (1) riverbed deformation from bank to bank in the final 500-km reach of the Mississippi River, (2) bed material transport at the Mississippi-Atchafalaya …
