Abstract
The height from top of check dam to bed of river, makes water impacting bed of river. And further, it endangers the safety of structure possibly. There have been many theses about local scouring. This research uses model of check dam with four kinds of height, and two kinds of mix grain, and several kinds of discharge of flow to confer impact force of over-fall flow and, depth of scour hole, and the location where water drops, and the reduce of energy by scouring. And compare with the formulas of former literature.
