Climate change is bringing more and more heavy downpours along with the resulting floods. So it is very important to plan cities in a more climate-resistant way. One of the possibilities here is to create floodable water-infiltration areas - known as wadis. Water is buffered in these areas. It remains standing for no more than 24 hours and gradually infiltrates the ground over that time. This reduces the pressure on drain systems and water-purification installations.
Planting wadis with trees helps them to function better: the trees absorb water which then evaporates and the water infiltrates deeper due to the tree roots. Trees that are suitable for planting in wadis are resistant against temporary flooding and temporary drought. After all, a higher infiltration capacity ensures faster water drainage and therefore drier ground.
Want to know which species are suitable for this specific location? Our TreeEbb makes searching very easy with the new filters ‘use > location > wadi’ and ‘location > other > tolerant to short-term flooding’. For wadis along roads, also select the filter ‘location > other > tolerant to salt spray’.
