Abstract: :To solve the problem of urban rainstorm water logging, a partitioned and stratified calculation pattern is used in the model which is established on the basis of two-dimensional unsteady flow theory and finite volume method improved by hydrologic budget. In view of complicated city water runoff, the model mainly simulates urban community, street, network of drains and river flow. Data of 10 rainfalls from 2009 to 2015 in the demonstration area of Tianjin is used in the model to analyze and compare the water levels of verification points and Jinhe river. Results show that both of the average values differ less than 10 cm, indicating that the model is of precision and can be applied to forecasting urban water logging. It provides a new method and idea for the mathematical modeling of urban rainstorm waterlogging.
Key words: rainstorm waterlogging, hydrologic budget, finite volume method, partition and stratification, urban waterlogging
