check dam
Stream flow reducer
A check dam is a small barrier built across a stream or drainage channel to slow water flow, reduce erosion, and capture sediment.
Unlike large dams that store water permanently, check dams are modest structures—often made of rocks, logs, or concrete—designed to control runoff rather than impound water: Farmers built check dams to prevent gullies from deepening.
