  1. Modeling to Support Green Infrastructure Planning Best Management Practice-Decision Support System (BMP-DSS) Application Andrew Parker Director, Water Resources Group www.modelingwater.com

  2. BMP-DSS Model • Component of Sustainable Modeling Toolbox (SuMiT) • Developed for detailed site-scale planning • Evaluate effectiveness of green technologies in a watershed • Considers hydrology and water quality • Models Best Management Practices (BMPs) • Can be applied at watershed scale • Includes post-processing capabilities • Available to the public (www.modelingwater.com)

  3. BMP Simulation • Two Major BMP Categories • Storage/detention • Open channel • Physical Process Representation • Evapotranspiration • Infiltration • Orifice and underdrain outflow • Weir-controlled overflow spillway • Bottom slope and roughness influence • General loss or decay of pollutant • Depending on design and type of BMP, any combination of processes may occur during simulation

  4. Analysis • Long-term • Weekly • Multi-storm

  5. In the works… • GIS Integration • BMP Optimization

  6. Case Study Integrate in-home and on-site water management to better manage storm water runoff at the site scale Water Conservation/Recycling Techniques

  7. Study Area • Bowie, Maryland, U.S.A. • Developing area • Lot size is approx. 1.25 acres • 26 % imperviousness (rooftop & paved area) • Pervious area (bare ground & gravel filled area)

  8. Approach • Generate surface hydrology input using watershed model (LSPC – part of SuMiT) • Run existing condition (A) • Run pre-development (O) • Run scenarios RT – Rooftop RG – Rain Garden PA – Pavement LF – Leach Field RG – Natural Ground

  9. Existing Condition (A) • Potable water from well • Rooftop and paved area are part of runoff • Septic system disposes of household waste

  10. Existing Condition (A) Values in 1,000 cubic feet • Potable water from well • Rooftop and paved area are part of runoff • Septic system disposes of household waste

  11. Scenario C • ALTERNATIVES CONSIDERED • Rooftop runoff diverted to cistern, overflow to rain garden • Recycled water is used for flushing • Pavement runoff to rain garden

  12. Scenario C Values in 1,000 cubic feet • Estimated Benefits • 33% Runoff Reduction • 27% Reduction in use of potable water

  13. Water Balance Annual Water Balance

  14. Storm Response Storm Event Analysis

  15. BMP-DSS Summary • Publicly available tool to support green planning • Designed for urban areas, but applicable elsewhere • Can be incorporated into larger scale watershed planning • Provides quantitative data for engineering design • Basis of systems developed throughout the U.S.A. for stormwater management and nonpoint source pollution control
