Abstract

Suspended sediment is supplied from river bed sediment in Hiyamizusawa Brook, Hokkaido, Japan, during the snowmelt season. The stirring up of fine grains from the river bed is an important control of the time variation of suspended-sediment flux. A model previously used to explain the stirring up of fine grains within a cobble and pebble bed is applied to a sand bed, with a modification . Consequently, the amount of fine material stirred up from the river bed is estimated from the grain size distribution of river bed sediment, and the suspended flux is thus calculated. The results were equivalent to the field data
