Abstract

Generally, sedimentation for reservoir planning was decided with reference to sedimentation of unit catchment area for near or in same channel network existing dams.However, sedimentation in the existing gams is controled by the flood discharge and is changeable each year, so annual mean sedimentation in existing dams are changeable with the period which use for the planning.In this paper, the author discuss to present a sedimentation in reservoir with daily rainfall and flood peak discharge.
