Swales
Swales are shallow vegetated open channels. They can be natural, but within a developed environment they’re usually designed as part of an engineered SuDS scheme. Typically featuring a wide-bottomed trapezoidal or parabolic cross-sectional profile for ease of maintenance and construction, the design also offers good hydraulic performance when combined with engineered SuDS systems.
