In this climatecafe the hydraulic capacity of a new watersquare is determined by young professionals from applied universities Rotterdam and Groningen in ‘s-Hertogenbosch. Eikendonkplein is a square that is used as a playfield but also as climateadaptive measure. How do the inhabitants of this square see the functionality of their front yard? How fast will the square overflow when intensive rainfall will flood our streets? How long will the water stay in the square? These questions are answered in this climatecafe with public and private stakeholders and published in scientific papers and social media. Impressions of this climatecafe can be seen here:
