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.
