Geomorphic work during a 150-year storm : contrasting behaviors of river channels in a New Zealand catchment

Auteur :
FULLER, I.C.

Description :
The geomorphic work accomplished during an extreme storm event by 3 primary tributaries in the western Manawatu river catchment (New Zealand) is assessed using sequential aerial photographs. Areas of floodplain and channel erosion were quantified as a measure of the work accomplished during floods triggered by a 150-year storm in February 2004. The contrasting amount of geomorphic work between these tributaries relates to valley floor and channel configurations, which prime discrete reaches for instability, sensitizing them to perturbation by this flood event.
