In this study, we measured the amount of micro-fine sand at many gauging stations in the Hinuma River Basin. As the result, we found that 1) we grasped the amount of micro-fine sand in river basin through simultaneous measurement at many gauging stations that located corresponding to the sub-river basin appropriate for sand supply, 2) the amount of micro-fine sand supplied from sub-river basin that has barren lands is too much since it differs among sub-river basins in the Hinuma River Basin, 3) the amount of sand supplied depends on flood characteristics in sub-river basins that supply much sand, 4) micro-fine sand are supplied from barren lands. Moreover, we will estimate the sediment discharge / catchment area / yearly sediment yield corresponding to land use/ that is available for the prediction of the sediment yield by making the data base of flood flow and relation of Q-Qs clear using many observed data in near future.
