Abstract

This study proposes a fundamental approach of developing the widely-distributed sediment yield/transport model coupling with the runoff model of Hydro-BEAM. On the background, we have the big problem of locating and tracing the scattered radioactivities via water, soil and organic matter movement. We, therefore, need to prepare numerical tools of predicting not only short-time but long-time transporting behavior of such radioactivities. We now focus on a sediment transport model to trace the movement of radioactive materials adherent to soils. We attempt to modify the conventional model of sediment transport into widely-distributed and macro-scaled one to be compatible with any distributed runoff models because a distributed sediment transport system necessitates the distributed runoff one to conduct coupling analysis. The numerical performance is demonstrated through the actual basin. The reasonable behavior can be recognized in these numerical tests.
