- Abstract
The runoff volume capture ratio is the primary indicator of sponge city planning. The design rainfall corresponding to the runoff volume capture ratio is very important for the sponge city planning. Based on the 30-year hydrological rainfall data of 39 cities (include Shennongjia Forestry District) in Hubei Province, the relationship between the design rainfall and the runoff volume capture ratio in Hubei Province was analyzed, and the annual runoff volume capture target and the regional division for total rainfall runoff volume capture target of cities were formed, which filled the gap in the annual total runoff control index of cities in Hubei. The relevant value suggestions will contribute to the planning and construction of sponge cities in the Province. The results showed that the runoff volume capture ratio was divided into three zones, corresponding to Zone II (80%≤α≤85%), Zone III (75%≤α≤85%) and Zone IV (70%≤α≤85%) respectively, and the design rainfall ranges were Zone II (10 mm≤H≤28.3 mm), Zone III (12.7 mm≤H≤39.5 mm), Zone IV (14.3 mm≤H≤49.0 mm) respectively. Shennongjia, Danjiangkou, Shiyan etc. are in Zone II, and 17 areas such as Xiangyang, Lichuan, Xuan' en etc. are in Zone III, Suizhou, Tianmen, Xianning, Huangshi, Xiaogan, Xiantao, Huanggang, Ezhou, Wuhan and other regions are in Zone IV.
