ClimateCafe Nijmegen May 2023, The Netherlands

As announced in our weekly ClimateCafe GreenBlue, testing of Sustainable Urban Drainage Systems as bio swales will be tested in Nijmegen. Climatecafe Nijmegen is planned in April/May 2023 for research the long term efficiency of climate adaptation measures that are previously mapped on Unique is a small set up with participation of several (applied) universities Radboud, HUAS Groningen with the Deltares, spearheaded by the municipality of Nijmegen.

Results: a high number of climate adaptation measures are mapped on and the unsaturated and saturated performance of bio swales will be tested (with infiltro meter test instead of full scale tests) which where implemented more than 5-20 years ago. Special attention is given to the bio diversity of the swales. The results are the backbone of a new maintenance program for the municipality that can be used on (inter)national scale for a better understanding of the required maintenance for a long term efficiency of Sustainable Urban Drainage Systems.

Impression of the testing and results: coming up soon

As an aquatic ecological and technical water manager Sidney has a broad experience local and regional greenblue management, civil enginering, ecological systems, GIS, and biochemical processes. Not surprisingly Sidney focusses on integral processes and knowledge development for his city Nijmegen and beyond. “A phonecall on a typical work day can be about a citizen in need of help with waterproblems in his street, while the next phone call can be from the ministries to talk about policy on climate adaptation”. Even though he mostly works in the field of application and management, scientific research is still in his blood. Therefore Sidney is working on sientific research on bluegreen and sewer climate adaptation measures (including supervision of internships). How do greenblue systems work on long periods and how can they function optimal in an ever changing, semi-crowded city as Nijmegen where both drought and to much water are challenges that needs to be asserted? Sidney is also part of several other knowledge platforms (Invasive Lobsters and climate change, COP-wave Infiltration pavement and Spiegelwaal warning systems) and regulary works with students from colleges and universities.
