Such dikes aim to shorten the length of slope, thus slowing down surface runoff and reducing soil erosion on arable land. They also support the infiltration into the soil. They need to be can be constructed in the direction of contours with a zero longitudinal slope. Both, the area in front of the barrier and its height must be corresponding to the need for retention volume of water, including the volume of deposited eroded material. Most frequently, they are constructed in the form of an earth embankment reinforced by grass.

Synergies may exist between heavy rain risk management measures and other development goals like environmental protection, health care, and economic performance. Harnessing them requires involvement of different actors, enforcement of exchange between you and them and holistic thinking.
