WebIn addition to controlling gully erosion, check dams also serve to slow the movement of water, allowing increased percolation into the soil. Just above a check dam is a good place to put in a percolation structure. Silt that builds up behind the dam creates good farmland, which can be planted after the rains while it retains moisture. Web2024). Check dams reduce erosion by reducing flow velocities. Sediment trapping can occur at lower flow velocities, but construction staff should not use check dams solely for this …
