Post-Fire Erosional And Hydrological Processes Promoting Debris Flow Initiation In A Douglas Fir And Western Hemlock Forest In The Riverside Burn Area, Oregon, Morena Nicole Hammer
Post-Fire Erosional And Hydrological Processes Promoting Debris Flow Initiation In A Douglas Fir And Western Hemlock Forest In The Riverside Burn Area, Oregon, Morena Nicole Hammer
Dissertations and Theses
Post-fire debris flows initiated by overland flow in the Pacific Northwest (PNW) are largely undocumented. Instead, debris flows are typically initiated by shallow landslides that result in a mud slurry of water and sediments traveling downhill under the force of gravity. However, because of the Fall 2020 fires in Oregon, the typical initiation style and erosional patterns in burned catchments may have changed because of unusually high burn severity. Due to the intensity of these fires, we set out to determine how hydrologic processes and erosion occurred, when they occurred, and what process was primarily responsible for the erosion that …
Quantifying The Environmental Performance Of A Stream Habitat Improvement Project, Cody Morse
Quantifying The Environmental Performance Of A Stream Habitat Improvement Project, Cody Morse
Master's Theses
River restoration projects are being installed worldwide to rehabilitate degraded river habitat. Many of these projects focus on stream habitat improvement (SHI), and an estimated 60%of the 37,000 projects listed in the National River Restoration Science Synthesis Program focus on SHI for salmon and trout species. These projects frequently lack a sufficient monitoring program or account for the environmental costs associated with SHI. The present study used life cycle assessment (LCA) techniques and topographic effectiveness monitoring to quantify environmental costs on the basis of geomorphic change. This methodology was a novel approach to assessing the cost-benefit relationship of SHI. To …
An Investigation Of Hydrogeologic, Stratigraphic, And Structural Controls On Acer Grandidentatum Communities In A Karst Landscape, Owl Mountain Province, Fort Hood Military Installation, Texas, Melinda S. Faulkner
Electronic Theses and Dissertations
The Owl Mountain Province is located within the Fort Hood Military Installation, an approximately 880 km2 installation established in the 1940s in Bell and Coryell counties, Texas, which has undergone extensive land use changes associated with military training, maintaining much of the vegetation in early succession. This study investigates thelithologic, stratigraphic, and structural controls on the hydrologic, hydrogeologic, and geomorphologic evolution of the Owl Mountain Province as expressed by mesic vegetation communities, including Pleistocene relicts Acer grandidentatum, within karst terrains. These systems exhibit complexly overprinted speleogenetic evolutions within a dynamic groundwater regime resulting from regional climate shifts throughout the …
Ranking Trails Based On Natural Hazards Instead Of Difficulty: A Case Study On Starved Rock State Park, Julia Ryherd
Ranking Trails Based On Natural Hazards Instead Of Difficulty: A Case Study On Starved Rock State Park, Julia Ryherd
Honors Program Projects
Starved Rock State Park in North-Central Illinois is not topographically flat as are many glaciated areas of Illinois. Its deep canyons and steep valley walls provide the backdrop for a diverse variety of natural hazards. Geologic hazards include steep canyon walls, flooding with erosion events, high elevation vantage points, and rock falls. Other natural hazards include falling tree branches and steep staircases. ArcGIS was used to record locations of both hazards and injuries along the trails and feature classes were made for each hazard. These feature classes were spatially joined and a weighted sum computed to create a hazard rating …
