Smart modelling for future proof rainwater systems: Sirio & Scan software Stormwater Poland 2018 15-16 March, Gdansk dr. ir. Vincent Wolfs
Situation in Belgium Climate change Floods Droughts Urbanisation One of the lowest water availabilities in Europe Pavement: 14,4%
Adaptive infrastructure Win-win use of open spaces Water Resilient Cities Smart systems Tools for strategic water planning = Sirio & SCAN
Developed at university KU Leuven, Belgium Standard software in Belgium Used by 50+ organisations Simulate 100 years in a second Get unique insights into your design Software to design climate-proof and optimal small-scale rain water systems using long term simulations State-of-the-art simulation engine Advanced technology in a user-friendly interface
Applications Sewer designs How much buffering? What is the impact of infiltration? How often will floods/overflows occur? Strategic water planning What is the impact of increasing urbanization? What are optimal source control measures? Rainwater harvesting How much water is available for reuse? What is the optimal design? Climate adaptation What is the impact of climate change? How can we make a city future-proof?
Fully automatic How does it work? Step 1 Create your design Translate your design to input parameters Step 2 Step 3 Simulate 100 years of rainfall Simulate long term series including climate change effects Statistical post-processing Direct translation from simulations to actionable insights
Example: new residential zone Infiltration ponds Green roofs and buffers How often does the system overflow? Are all buffers used effectively? How much water (%) will infiltrate? How much will pass to downstream?

Results Is the design sustainable? 41% will infiltrate 39% will be reused
Results What is the impact to downstream? Is the design How sustainable? much will 41% overflow? will infiltrate 39% will be reused Once every 5 years, an overflow event occurs Check overflow volumes for different return periods
Example: new residential zone Are the buffers being used effectively? Maximum for 50% filled! (over 100 years )

Application 1: Intelligent real-time flood control Can we control these hydraulic structures more effectively to reduce flood damage?
Model implementation Highly accurate Floodplain Reservoir Fixed HS Adjustable HS Transfer function Input (RR, GL)
Massive flood damage reductions possible without investments 1 million damage reduction
Application 2: Intelligent green roof
Application 2: Intelligent green roof MITIGATE RAINFALL PEAK FLOWS REDUCE RUNOFF VOLUMES OPTIMIZE WATER AVAILABILITY
Upscaling What is the impact on urban floods? And including climate change? What is the impact on city heat stress? What is the optimal outflow regulation strategy? How much water is available for local irrigation? How well does the roof vegetation survive in dry periods? What is the potential of real-time control? (e.g. in function forecasted precipitation, monitored levels in urban drainage system, )
