TL;DR: The term "urban stream syndrome" describes the consistently observed ecological degra- dation of streams draining urban land as mentioned in this paper, which can be attributed to a few major large-scale sources, primarily urban stormwater runoff delivered to streams by hydraulically efficient drainage systems.

TL;DR: In this paper, the authors suggested that the primary degrading process to streams in many urban areas is effective imperviousness (EI), the proportion of a catchment covered by impervious surfaces directly connected to the stream by stormwater drainage pipes.

TL;DR: Comparing experiences from Australia and the United States, two developed countries with existing conventional stormwater infrastructure and escalating stream ecosystem degradation, are highlighted to highlight challenges facing sustainable urban stormwater management and offer several examples of successful, regional WSUD implementation.

TL;DR: In this article, a suite of water quality variables, such as dissolved organic carbon (DOC), filterable reactive phosphorus (FRP), total phosphorus (TP) and ammonium, along with electrical conductivity (EC), along with the proportion of impervious area directly connected to streams by pipes or lined drains, are investigated.

TL;DR: In this article, the authors compared the hydrologic effects of two conventional approaches to urban stormwater management, namely, drainage efficiency focused and pollutant load reduction focused, and proposed an approach, flow-regime management, which aims as much as possible to restore and protect ecological structure and function of urban streams by retaining the preurban frequency of untreated storm flows, reducing the total stormwater runoff volume through evapotranspiration or harvesting, and delivering filtered flow rates to match pre-urban baseflow rates.
