| Abstract: | The author used the both theories of geograpny and hydraulics to study the breack-down-hill of granite area in the subtropical zone of Kwangbong. about: (1) every period of the generation process. (2) the erosion action of the subsurface-flow. (3) the erosion action of the surfaceflow. (4) the sand eroding capacity and the sand transporting capacity, and (5) the types of breack-down- hill and the over surface watershed. Second, the author directs "The water and sand loss forcast mathmatis model" (Kwangdong water loss and soil erosion area), the model has good effects to forecaste in the Wo-Var river watershed. |
