Abstract

The interception of rainfall was observed at an outdoor urban scale model site. The model dimensions were 50 x 100 m, with 1.5-m cubic roughness blocks arranged uniformly. The amounts of rainfall and runoff within the area of 6 x 6 m were measured. In this study, we introduced the specification of the facility and preliminary results of rain events which were obtained in September 2006. Mean rainfall intensity of the rainfall events ranged from 0.6 to 1.4 mm hour<SUP>-</SUP><SUP>1</SUP>. Under these rain events, the ratio of runoff to rainfall decreased as the rainfall decreased. This tendency was commonly found in both the total rainfall and the real-time rainfall intensity.
