Predicting Ecological Effects of Watershed-Wide Rain Garden Implementation Using a Low-Cost Methodology

摘要: AbstractStormwater control measures (SCMs) have been employed to mitigate peak flows and pollutants associated with watershed urbanization. Downstream ecological effects caused by the implementation of SCMs are largely unknown, especially at scale. Knowledge these could help setting goals for targeting locations local restoration efforts. Unfortunately, studies such as typically require a high level time effort investigating party, which resources often limited. This study proposes low-cost investigation method prediction on scale rain garden systems using publicly available data software. For demonstration purposes, typical urban was modeled Storm Water Management Model (SWMM) 5.0. Forty-five models were developed in percent impervious area varied 3 80%, fraction gardens implemented respect number of...
