The slope of downstream face is kept backward and of upstream face it is generally vertical. Maximum recommended crest height of around 500mm. Check dams heights should allow for pools to develop upstream of each check dam, extending to the downstream toe of the check dam immediately upstream. The slope of downstream face is kept backward and of upstream face it is generally vertical.
