In Japan, urbanization in recent years leads deforestation and the grounds paved with concrete or asphalt. It prevents the rain penetrating into the soil and all the water to flow to the river directly. In the result, it causes not only flooding when torrential downpour hits the city, but also water shortage and deterioration of river water during rainless season. Furthermore, the rain water of sudden torrential downpour caused by extreme weather could exceed easily the urban water discharge capacity and turn into a disaster in a very short time. As an actual case, Japan was hit by a record amount of deadly torrential downpour of 138.5 mm per hour which result in injury and loss of life in July 2013.
