Abstract:
Low impact development is taking the design idea of natural hydrology, source control and decentralized management as the core, which is more in line with the strategy of rainwater management for the sponge city construction. Urban storm simulation which contains LID modeling is one of the key technologies for the rainwater system construction of the sponge city. However, at the present stage, the research of the LID model setting and parameter analysis is very limited. By sorting and analyzing the LID simulation publishing in the mainstream literature and journals in recent years, six common LID models were selected for module analysis and parameter collection, aiming to provide data support for LID simulation in different regions through systematic survey and review. Finally, two kinds of related LID measures (green roof and permeable pavement) were selected, and the establishment of LID model, rainwater control simulation and effectiveness evaluation were realized in the research area.
