Geological Survey through an internship award from the National Science Foundation.Īt the University of Michigan, Dr. For this project, he collaborated with geoscientists at the Landslides Hazards Program in the U.S. As a doctoral student, hHe led a study assessing the influence of rock strength on the map distribution and volumes of eroded sediment following the 2018 Woolsey Fire in southern California using repeat airborne-LiDAR surveys and field mapping. Townsend also resolved the timing of initiation and propagation of tectonically active fault systems in southern California from thermochronology and structural geology analyses. Townsend mapped earthquake-triggered landslides from aerial and satellite imagery, modelled regional distributions of rock-mass strength from inversion of topography and mapped landslides, and applied field geotechnical approaches to characterize and quantify variability in the strength of fractured rock masses. His doctoral work focused on the role of scale-dependent rock-mass strength in controlling the erosion and morphology of mountainous topography. He has also been involved in geologic and geotechnical field investigations of landslides, debris flows, soil creep, fault rupture, earthen dam failure, wetland restoration, mine remediation, and archeological resources. He has experience with technical software including ArcGIS, CloudCompare, LASTools, SeisImager, MATLAB, and GeoStudio.
He also has experience with the application of remote sensing technologies and LiDAR, shallow seismic and electrical resistivity surveying for near-surface investigations, logging and characterizing stratigraphic sections, OSL geochronology and radiocarbon dating, and USDA soil taxonomy. He specializes in the characterization of weak and fractured rock masses, mapping and quantifying erosion following wildland fire, and digital terrain analyses for erosion and slope stability problems. Townsend is a geologist and geomorphologist with experience in near-surface geophysics, geochronology, and geomorphic and geologic site characterization through field mapping, digital topographic analyses, satellite photo analyses, and subsurface investigations.
