Formerly natural waterway flowing through heavily populated area
An urban stream is a formerly natural waterway that flows through a heavily populated area. Often times, urban streams are low-lying points in the landscape that characterize catchment urbanization.[1] Urban streams are often polluted by urban runoff and combined sewer outflows.[2]Water scarcity makes flow management in the rehabilitation of urban streams problematic.[3]
