Description and Quantification of Debris Tongue Movement in a Retrogressive Thaw Slump Using Aerial and Terrestrial Photogrammetry
Retrogressive thaw slumps can modify large areas of the landscape and pose a significant threat to linear infrastructure in the Arctic. There is little published information on how retrogressive thaw slump debris tongues develop. This thesis demonstrates a novel technique for combining information a...
