WATER CYCLE LANDSCAPE DESIGN AND ECOLOGICAL EFFECT ANALYSIS OF RAINWATER GARDEN IN SPONGE CITY

. To address low efficiency of urban runoff control and insufficient reduction of runoff pollutants in China, this study designed a rainwater garden system based on Sponge City principles. The rainfall and hourly rainfall time series data for Sponge City were determined, using a Chicago rainfall pattern, based on local meteorological data including runoff coefficient, catchment area, and rainfall duration
