• In managing the Ishikari River, it is necessary to evaluate sediment discharge along its entire length. Sediment discharge from tributaries into the main stream therefore was in vestigated. Two numerical models that take into account tributaries are proposed which were tested for the 1981 Ishikari River flood. The sediment discharges calculated with these models were compared with receded values. Results show that it is necessary to consider tributary effects directly and that sediment discharged from tributaries contributes to the output sediment discharged from the river's mouth.
