A Discussion Of Factors Involved In The Formation Of Slab Avalanches And An Analysis Of Avalanche Risk In The Sierra Nevada Mountains Using Gis, Kevin C. Howen
Natural Resources Management and Environmental Sciences
As winter recreational activities increase in mountainous environments, the need for a better understanding of snow avalanches is necessary. This project consists of a study into the physical factors that contribute to slab avalanche formation, and a GIS analysis of an avalanche prone area within the Sierra Nevada Mountains. The primary physical factors that contribute to the conditions that lead to avalanches include the slope of a mountain face, the aspect, and bare ground conditions lacking thick forest vegetation. ArcGIS is a powerful software tool that was used to map each of these factors, and then combine them to create …
Creation Of Soil Liquefaction Susceptibility Maps For San Luis Obispo & Marin Counties Using Geographic Information Systems., Amelia M. Lowman
Creation Of Soil Liquefaction Susceptibility Maps For San Luis Obispo & Marin Counties Using Geographic Information Systems., Amelia M. Lowman
Earth and Soil Sciences
Liquefaction of soils in response to earthquake shaking is a pressing issue in the state of California. Using Geographic Information Systems, Geological and lithology layers, along with criteria in order to separate out the data into four risk categories, a liquefaction risk assessment map was created for San Luis Obispo and Marin Counties. The accuracy of these maps was then assessed using liquefaction occurrences for San Luis Obispo County, and it was determined that while the map is somewhat accurate, in order to obtain a greater amount of accuracy and increase the usefulness of these maps, more data would need …
