BLM OR-WA Landslide LiDAR Mapping within Mill Creek Watershed, Coos Bay District
LiDAR is relatively new data and it gives us much better images of surface geomorphology, allowing identification of features associated with landslides. Identification of landslide features is an important first step for further geologic hazards studies for forest and land management activities, road building, disaster prevention etc. This will be the first detailed LiDAR landslide mapping project within the Coos Bay District. This project will map landslides, which have occurred within the Mill Creek Watershed, to State of Oregon standards. The area to be mapped is approximately 23,808 acres. The main features observable in LiDAR are debris fans, deep-seated slides, earthflows, and rock falls that occurred before the LiDAR was flown (2008). Typically the shallow soil slides are not evident in LiDAR. In addition, a list of attributes will be collected for each feature. Most (90%) of the project is completed in the office, but features will be field verified as time allows.
