Applications
Sewer designs
Rainwater harvesting
Strategic water planning
Climate adaptation
How much buffering?
What is the impact of infiltration?
How often will floods/overflows occur?
How much water is available for reuse?
What is the optimal design?
What is the impact of increasing
urbanization?
What are optimal source control
measures?
What is the impact of climate change?
How can we make a city future-proof?
How does it work?
Step 1Translate your design to input parameters
Create your design
Step 2
Step 3
Simulate 100 years of rainfallSimulate long term series including climate change

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
Is the design sustainable?
✓ 41% will infiltrate
✓ 39% will be reused
What is the impact to
downstream? How much will
overflow?
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!

approach
The future: smart integrated modelling
New self-learning modelling approach (Wolfs et al., 2015 & 2017)
✓ Ultra-fast models: enabling a vast range of applications
✓ Use artificial intelligence: models learn from sensors and can update
themselves in real-time
✓ Proven: applied in various operational settings in Europe
✓ Versatile & open: the models can be included in any operational monitoring

Application 1: Intelligent real-time flood control
Can we control these hydraulic
structures more effectively to
reduce flood damage?

• 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, …)
