Dry retention reservoirs with a constant flow
Various types of retention basins through which a watercourse flows. There is always a barrier across the course of the watercourse, and during low water the watercourse runs unhindered through the bottom outlet. As soon as more water flows than the standard discharge of the bottom outlet allows, this increased discharge is held back and the basin gets flooded. Basins for flood retention can either be constructed dry or with a permanent storage area.
