Sitka debris flow hazards
Project Details
Project ID:
1553
Nickname/Abbreviation:
Sitka landslide
Parent Project:
Unstable slopes
Status:
Active
Description:
Response to August 18, 2015, Kramer (Harbor Mountain) landslides, Sitka, Alaska. Subsequent work to coordinate initial lidar data collection by the Army Corps of Engineers Cold Regions Research and Engineering Laboratory (CRREL) in Sitka, and conduct subsequent DGGS lidar data collection. Lidar imagery and field data are being used to evaluate potential landslide hazards. CRREL lidar data collection funded by the National Park Service (Grant # P15AC01879) and DGGS lidar data collection was funded by State of Alaska General Fund and National Park Service (Grant #P17AS00903); lidar analysis and landslide evaluation funded by FEMA (2016 CTP Grant # EMS-2016-CA-0006).
This study aims to develop a debris flow hazard map for the City of Sitka. We use lidar, field observations, and computer modeling to understand where debris flows could happen in the future. Follow-on work funded by RAND Corporation to collaborate with Sitka Sound Science Center and other partners to develop Landslide Ea
