The last word has certainly not yet been said about a wadi. But the benefits are clear. You collect the water in your garden and let it slowly penetrate into the ground. Attention you want to start farming. Then you better look at the concept of Keyline on our site or via this youtube video
For cities and municipalities it is an ideal way to provide a buffer zone in case of heavy rainfall when the sewers can no longer absorb the water. But we can also provide a place in our own garden. Of course you don’t put that on the highest point. Take a look at where all the water is already flowing today.
If you are still in doubt whether or not you should plant that Wadi, you can take a look at the website of Duurzaam Groen. But studies show that by planting, the Wadi can absorb even more water.
On the Climatescan.org website you can see all the places where a wadi has already been constructed. That is a feat by Floris Boogaard, who has been studying all things Wadis for more than 20 years. Be sure to take a look at this website if you really want to become a specialist. Because you will find a lot of smart thinking there. Enschede in the Netherlands is somewhat of a pioneer in our low countries and has about 200 Wadis.
This is a nice video from the province of Flemish Brabant that explains how to tackle it on a small scale.
