Influence of a Series of Sabo Dams on Debris Flow Deposition

Abstract

Since ancient times, debris flow has been recorded. It is a kind of mixture flow of water and sediment. It causes damage of human's lives and properties. Large boulders in the front of surge and big destructive force are common for debris flow. To mitigate debris flow disaster, various kinds of sabo dams have been constructed. Control function of such Sabo dams have been reported through a lot of studies. However there are still few studies about combination of sabo dam. In this study, experimental and numerical works have been performed for influencing on capture capacity of sabo dam by upper located sabo dam. Results indicate that depending on the conditions of arrangement of sabo dam can affect the storage capacity.
