A PROPOSAL OF URBAN STORM RUNOFF MODEL CONSIDERING GREEN INFRASTRUCTURES AND ITS APPLICATION

Abstract

 In the low-impact development of urban areas, storm runoff control drainage systems combining land drainage channels and rainwater regulating ponds are developed to reduce the load on rainwater runoff. In order to confirm the effect of storm runoff control drainage system, a method for modeling a detailed rainwater runoff process using urban landscape GIS data that can faithfully represent a complicated urban structure. In this study, we constructed a urban landscape GIS considering the rainwater runoff control drainage system in Augustenborg area, and showed the effects of green roof and runoff control type open channel by simulation.
