Urban stream syndrome (USS) is a consistent observed ecological degradation of streams caused by urbanization. This kind of stream degradation is commonly found in areas near or in urban areas. USS also considers hydrogeomorphology changes which are characterized by a deeper, wider catchment, reduced living space for biota, and altered sediment ...
Urban stream syndrome is a consistently observed trait of urbanization characterized by high nutrient and contaminant concentration, altered stream morphology, increased dominance of dominant species, and decreased biodiversity [29] [52] The two primary causes of urban stream syndrome are storm water runoff and wastewater treatment plant effluent.
While historically pure, the stream now suffers from urban stream syndrome, partially due to the amount of impervious surfaces within its watershed.

Water Sensitive Urban Design with Green Infrastructure in the bottom right corner.. Water-sensitive urban design (WSUD) is a land planning and engineering design approach which integrates the urban water cycle, including stormwater, groundwater, and wastewater management and water supply, into urban design to minimise environmental degradation and improve aesthetic and recreational appeal.
