Create a Swale
A swale is a u- or v-shaped channel, usually vegetated or covered with mulch, that slows stormwater runoff and increases the time available for water absorption. The vegetation or mulch begins the filtering process that continues in the soil.
Note that before implementing this infiltration practice, it is highly recommended to determine the soil permeability.
