Run off Quantity Controlling: Two small triangular sites are designed as “Ripple Gardens”. We conduct planting design experiment in a triangular parcel to compare short bushes with lawns. The canopy tree is the most efficient element in storm water management because of prolonged rainwater dripping period. The slope of the lawn and the wave can be adjusted to realize best infiltration effect without triggering water-logging or speedy flow. We examine different hardscape materials in a semi-circular parcel. The space between the waves adopts different pervious material (the bark, the ceramics, the gravel and sand etc.). The edge of the waves is designed to observe and compare the overflow amount of different materials.
