Early summer low flows

Stage = 0.313 m, Discharge = 0.48 m3/s

Early June, before the arrival of the seasonal rain front, is a period of low flows. Since the floods over 17-19 May there has been a period of almost continuous flow recession, only interrupted by a minor rainfall event on June 1st (see stage hydrograph plotted below).

Today's discharge measurement plots very close to the stage-discharge curves developed before the 19 May flood, indicating that the aggradation of the channel seems to have been temporary. The red symbols plotted below represent the three most recent measurements taken since the flood. Only the first measurement taken at stage value 0.65 m is significantly different from the established curves. Points plotting to the right of the curves indicate channel aggradation (sediment deposition), while points plotting to the left of the curves indicate channel degradation (erosion of the channel bed).
