Ecological rainwater infiltration in landscaping Xiamen, China

This infiltration pilotproject took place in Xiamen, Haicang district; a tourist city on the coast with 3.5 million inhabitants. They are very strict on maintenance of green areas such as green belts alongside roads, city gardens and other green areas. There is a considerable challenge with regard to the health and resistance of plant borders and trees against wind and landscape influences in this subtropical climate. The soil type in this area is mainly silt of which the penetration speed is very low and the drainage speed therefore very slow. The Hydrorock pilotproject took place over a length of 100 meters and a width of 38 meters.
