Considering characteristics of high river density, special underlying surface in plain network region, and municipal drainage system function, unit model is proposed, which defined as a region surrounded by main or embankment. Flood storage variety control projects regulation small rivers each simulated. With catchment an object, according to its capacity, simplified was developed. Coupling model, 2D flood routing urban analysis for tidal developed, could be applied analyzing from upstream river, storm surge local rainfall. Demonstration research carried out Puxi protected area Shanghai.
