TL;DR: In this article, the authors describe elevation data sources, digital elevation model structures, and the analysis of digital elevation data for hydrological, geomorphological, and biological applications.

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, 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.

TL;DR: An Index of Stream Condition (ISC) as mentioned in this paper has been developed to assist broad scale management of waterways by providing an integrated measure of their environmental condition, which is intended for use by managers at state and regional levels and can be used to report on stream condition.
