Popis: The run-off of the rain fall is very complex because it has various characteristics especially at the mountainous basin. If a run-off phenomenon can be reproduced well, the prediction of the sediment movement and so on become possible and effective to control and maintain the river channels.In this study, authors have developed the prediction model in which wash load was evaluated by using the channel network of the digital national land information and the kinematic wave model. The model can evaluate the flow rate and the sediment transport rate at any station in the river basin. The geographic and geological informations were obtained from the Ishikari River Area LandscapeIntelligences. It was applied to the Jouzankei Dam basin and compared with the field observations.
