Chapter 7: Opportunities to satisfy urban water needs while addressing the urban stream syndrome
ExtractThis chapter examines the little explored problem of the urban stream syndrome – a condition in which the health of urban streams is poor. Notable symptoms of this stream syndrome include altered stream flow, morphology, water quality, and ecosystem structure and function. While underlying causes of the urban stream syndrome vary among watersheds, in general its hydrologic symptoms are associated with: replacing grassland and/or forests with impervious surfaces such as roads, parking lots, roofs and sidewalks; building drainage and flood control infrastructure to rapidly convey storm water runoff to streams (so-called formal drainage systems); and altering catchment water budgets (for example, through water imports and exports). Increasing imperviousness reduces infiltration and evapotranspiration of rainfall, while formal drainages increase the hydraulic connectivity between watersheds and streams.
