A flood park is a type of green infrastructure designed to combine recreational, ecological and water management uses. Under normal conditions, it works like a conventional urban park, but it is prepared to collect, store and laminate water during episodes of intense rain, preventing flooding in the urban environment.[1]​.

Flood-prone parks have a topography adapted to allow the temporary accumulation of water. They include elements such as:

These spaces can store tens of thousands of cubic meters of water, which is then released in a controlled manner or reused for urban irrigation.
