Designing Sustainable Drainage Systems

  1. 1. Designing Sustainable Drainage Systems Jo-fai Chow, STREAM Research Engineer Dragan Savic David Fortune
  2. 2. What is the problem? • Urban flooding & overflow pollution • Vulnerability of conventional drainage systems – Building bigger pipes and storages CANNOT solve the problem • Population growth and Urbanisation • Climate uncertainty and extreme weather events
  3. 3. Moving forward • SuDS: Sustainable drainage systems • Change of focus: conveying → source control • Recommendations: legislation, regulations, technical guidance & best practice • Different requirements: new developments and retro-fitting • How to make the best informed decision ???
  4. 4. STREAM Research Project • STREAM – industrial doctoral centre for the water sector • Strong industry involvement • Exeter – artificial intelligence applications for water industry • Micro Drainage – Developer of UK industry standard drainage design software • Goal – Developing a better decision support system for sustainable drainage design
  5. 5. Key R&D Tasks Guidance System Optimal Selection of SuDS / Pipes etc 1D/2D Flood Simulations Monte Carlo Design Analysis User Requirements Research & Development Fuzzy Expert System Multi-objective Optimisation Framework Software Acceleration (e.g. Cellular Automata) Software Acceleration (e.g. MOGA-ANN) Hardware Acceleration (Parallel Processing and GPU Computing) e.g. Maryam Astaraie-Imani Exeter e.g. Michele Guidolin Exeter
  6. 6. Goals • “Behind the scene” algorithms – Speeding up individual tasks to achieve higher overall efficiency • Trade-off curves for decision makers • Visualisation
  7. 7. Summary • SuDS are the way forward • STREAM Research Project – Exeter (A.I.) + Micro Drainage (Software) • Better Decision Support System: – Quicker turnaround time – Trade-off curves for decision makers – More scenarios, more simulations and more confidence!
