ABSTRACT

Advance of computer technology have helped not only to perform the qualitative analysis, but also to make quantitative analysis on the landscape evolution. The advanced landscape evolution model can predict the future change of landscape as well as prove the previous landscape model. However, there is little research for using landscape evolution model for determining each landscape process in Korea. This research has attempted to introduce the theoretical frame in 1- dimension bedrock channel model and to simulate the model for understanding the effect of parameters controlling the change in channel geometry. The result of this study indicates that the rock uplift rate has a greater effect on the development of longitudinal profile than rate of erosion and degree of basin wideness also changes the longitudinal profile than others. This study suggests the fact that if we consider other geomorphic processes and combine them with this simple model, we can tell more stories about the landscape evolution processes.
