Assessment of potential aggradation hazards through the dating of river surfaces, Westland, NZ
Westland, New Zealand is situated on the western side of the Southern Alps of the South Island, where steep slopes and high rainfall lead to large amounts of erosion and sedimentation (or aggradation). Earthquakes on the Alpine Fault or another fault in the area can lead to landslides and increased aggradation of Westland’s rivers, which has the potential to infringe upon agriculture, industry, and infrastructure. By dating the river surfaces, it is intended to create an aggradation hazard map that could be of use for future hazard response and infrastructure planning.
