Designing Sustainable Drainage Systems
Jo-fai Chow, STREAM Research EngineerDragan Savic
David Fortune
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
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 ???
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
Key R&D Tasks
Guidance System
Optimal Selection of SuDS / Pipes etc
1D/2D Flood Simulations
Monte Carlo
Design Analysis
UserRequirements
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-ImaniExeter
e.g.Michele GuidolinExeter
Goals
• “Behind the scene” algorithms– Speeding up individual tasks to
achieve higher overall efficiency
• Trade-off curves for decision makers
• Visualisation
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!
