| Research Abstract |
By flume experiments, characteristics of the topological development of stream channels on fans were investigated. The effect of its history (hysteresis) was observed in migration and avulsion of channels. Besides, it was found that the inverse problem of Kolmogorov model dealing with layer thickness distribution could be solved under particular conditions. In this work, the constant probabilistic function of erosion and sedimentation amounts were assumed. A model that can well reproduce hysteresis is a future work.
