Construction method of rainwater source regulation and storage system of sponge city

The invention discloses a construction method of a rainwater source regulation and storage system of a sponge city, belongs to the technical field of sea surface cities, and aims to provide the construction method of the rainwater source regulation and storage system of the sponge city with wide applicability. The method includes: S1, confirming a site; S2, estimating the runoff volume of the siteby surveying the structural composition and soil elements of the site; s3, establishing a data model according to the historical data, and estimating the urban rainwater flow through the data model;and S4, constructing a rainwater regulation and storage system according to estimation results of S2 and S3. Flow estimation and specific site application of urban rainwater are carried out; a corresponding rainwater regulation and storage system can be reasonably designed; a set of complete rainfall flood management and control system is constructed, the rainwater drainage process is optimized, the surface quick drainage
