Enhancing a rainfall-runoff model to assess the impacts of BMPs and LID practices on storm runoff.

摘要: Best management practices (BMPs) and low impact development (LID) are increasingly being used as stormwater techniques to reduce the impacts of urban on hydrology water quality. To assist planners decision-makers at various stages projects (planning, implementation, evaluation), user-friendly tools needed assess effectiveness BMPs LID practices. This study describes a simple tool, Long-Term Hydrologic Impact Assessment-LID (L-THIA-LID), which is enhanced with additional practices, improved approaches estimate quality, representation in series (meaning combined implementation). The tool was evaluate performance individually 30 years daily rainfall data four types idealized land use units watersheds (low density residential, high industrial, commercial). Simulation results were compared other published studies. simulated showed that reductions runoff volume pollutant loads after implementing both series, comparable observed these L-THIA-LID 2.0 model capable assisting decision makers evaluating environmental thereby improving decisions.
