In order to deal the problem that many scholars lack the concept of catchment interval when modeling the waterlogging point, the method that can extract catchment characteristics of waterlogged points in the gentle rolling area of city has been established based on DEM and traditional D8 method to determine the flow direction and the filling of depressions. The depression, where the waterlogged points are located, was regarded as a “true depression”, which was not involved in the calculation of cycle filling. The DEM data of 5 m resolution for the Jiaonan District of Qingdao City was tested by the above method and 15 of the 18 waterlogging points were accurately identified, where the hit rate was 83%. In addition, the corresponding catchment characteristics were also extracted, and the water accumulation degree as well as the risk grade of each waterlogged point was analyzed by using the method. The No. 11 waterlogged point at Xiqueshan road is the most dangerous and potentially harmful. This method can better extract the catchment characteristics of waterlogging points in the urban area, exhibiting a reference value for the city’s flood control and disaster mitigation.
