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 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.
St. George street is the site of this former stream, which now flows through the sewers and a culvert. This paved street will be converted into a shared-use path, riparian habitat, and urban greenspace. [24] St. George Creek once spawned salmon and trout, and hosted a diverse riparian ecosystem.
Ecosystem service flows along the urban rural continuum. In socioecology, urban areas are considered part of a broader social-ecological system in which urban landscapes and urban human communities interact with other landscape elements. [2]
Therefore, stream ecosystems cannot be studied in isolation. Streams are dynamic and therefore produce a lot of energy. This occurs due to their movement of water and sediment through a stream system. "The faster the stream flows, the greate the power it has to erode and carry sediment. [6]" A way a stream can dissipate this energy of flowing ...
These include land-disturbing agricultural, silvicultural, urban, industrial, and construction activities from which hard-to-monitor pollutants emerge during wet-weather events. Pollution from these landscapes has been almost universally acknowledged as the most pressing challenge to the restoration of waterbodies and aquatic ecosystems ...
Also in terms of carbon transport from terrestrial ecosystems to aquatic ecosystems, riparian groundwater can play an important role. [19] As such, a distinction can be made between parts of the riparian zone that connect large parts of the landscape to streams, and riparian areas with more local groundwater contributions. [20]

The environment of New York City consists of many interwoven ecosystems as part of the New York–New Jersey Harbor Estuary.The climate of New York City shapes the environment with its cool, wet winters and hot, humid summers with plentiful rainfall all year round.
