During the flood period, there is a very sharp depletion of benthos in river beds, especially on sanbars, mainly as the result of active drifts. The number of organisms passively drifting in two days of floods is equal to their number living along a 2-kilometer line of the river prior to the flood. Comparatively smaller forms are washed away from rocks and larger specimens from the sand. The number of animals at reaches and on sandbars was not restored one month after the floods.
