• Abstract:
  Frozen debris lobes (FDLs) are slow-moving landslides within permafrost on slopes located in ; the Brooks Range of Alaska. Forty-three FDLs are located within the Dalton Highway corridor, ; with 23 occurring less than one mile uphill of the Dalton Highway and the Trans Alaska Pipeline ; System (TAPS). Although slow-moving for landslides, their size and close proximity to ; infrastructure make FDLs geohazards. This project used remotely sensed data from multiple ; acquisition methods to monitor and analyze FDLs at different temporal scales, thereby ; increasing our understanding of rates and episodes of movement of these geohazards. Each ; technique was evaluated for its overall cost, east of use, and applicability to assess the flow ; dynamics of FDLs. This research involved: 1) measuring surface movement in the field with a ; differential GPS unit; 2) analyzing remotely sensed data using multiple data acquisition methods ; (i.e., historic optical imagery, LiDAR data, InSAR data, and UAS-acquired photography) to ; monitor and analyze the FDLs at different temporal scales; and 3) summarizing and ; synthesizing the research results, making them available to the public and to the agencies with ; a vested interest in FDLs through several different deliverable formats.
