Autumn rains and colours

Autumn rains sustained moderately high discharge through early November. It seems to have been enough to move the sediment pulse through the reach so that we are returning to the previous stage-discharge curve (before flood of August 1). Channel aggradation with fine gravel (due to a sediment pulse) often occurs in Takiya River after major floods, but this year the aggradation seems to have been quite short-lived.

We walked the channel up to a large landslip area about a kilometre upstream. This landslip is a major source of sediment for these sediment pulses which move downstream.
