Continuous Quantity and Quality Modeling for Assessing the Effect of SUDS: Application on a Conceptual Urban Drainage Basin

Abstract The development of computational tools based on urban drainage models is fundamental for the correct selection SUDS. present study proposes a systematic approach continuous modeling USEPA SWMM. objective was to select most suitable Sustainable Urban Drainage Systems (SUDS) by evaluating several aspects related their design and configuration. proposed methodology applied conceptual watershed with meteorological information from Santander, Spain. analysis SUDS parameters showed that only surface variables sensitivity ?20% berm height vegetation volume. optimal configuration case train consisting green roofs, permeable pavements, vegetated swales rain gardens, 1% total subcatchment area cover, one structure, semi-aggregated spatial distribution. proved efficient but also highly dependent conditions. have different efficiencies (30%—90%) in reducing runoff volume, peak flow, pollutant loads depending region where modeled. be studying combinations interconnection seven typologies, as well effect configuration, distribution performance.
