Wadi's are landforms formed in dry areas. They have steep canyon walls and are usually filled with water during the rainy season. The water mixes with the sediment and rock at the bottom of the canyon and creates a type of wetland ecosystem. The wadi is important for wildlife, plants, and humans because it is a great source of water during the dry season. It's also an important part of the local culture because of its spiritual and historical importance. The wadi also helps prevent flooding by capturing water during the rainy season and releasing it gradually during the dry season.
