| 摘要 | It is an important standard to judge the flood disaster in the basin whether the rainfall at the flood-inducing interface is reached. In this paper, the Xin'anjiang model, Topmodel model and SCS model were selected to calculate and compare the rainfall at the flood-inducing interface in the Zhanghe Reservoir basin in Hubei Province. The results showed that average relative error and average absolute error of Xin'anjiang model were -3.36% and -21.46×105 m3, which were the minimum, followed by Topmodel model with 5.72% and 26.22×105 m3, SCS model with 11.33% and 58.13×105 m3. The minimum absolute error of the three hydrological models in calculating the rainfall at the critical interface was 3.26 mm, while the maximum was 49.24 mm. When the initial water level exceeded 120 m, the difference among the three models in calculating the rainfall at the critical interface became more and more obvious. When the reservoir water level was lower than 120 m, it mainly referred to the calculation results of Xin'anjiang model. When the reservoir water level was higher than 120 m, it mainly referred to the calculation results of Topmodel model. The research conclusion can provide reference for small and medium-sized basins selecting hydrological model to calculate the rainfall at the flood-inducing interface. |
