While sampling the sediments deposited by the September 2013 Colorado floods, the scientists observed that roads (Left Hand Canyon highway) and houses built on the outside bends of river meanders were particularly vulnerable to flood damages.

Erosion along Alaska’s Arctic coastline near the village of Kaktovik
Erosion along Alaska’s Arctic coastline near the village of KaktovikNeal Pastick – lead author of the study – investigating erosion along Alaska’s Arctic coastline near the village of Kaktovik. Permafrost-dominated coasts of Alaska have drastically changed as the result of coastal transgression and storm-surge flooding which can result in the loss of cultural sites and damage to infrastructure.
