Abstract

A flood event occurred on 30 September 1997, in 3 catchments, Torrealvilla, Salada and Nolgate, which were being monitored for morphological change. Detailed topographic surveys were made before and after the flood and from these DEMs of difference were constructed. The 2 sites with highest flows both underwent significant incision of the channel. Elsewhere, within the channels major erosion took place downstream of tracks and structures such as check dams that impeded sediment movement. The pattern and amounts of change show a scale effect of peak discharge. Behaviour of channels is closely related to local sediment supply
