A modified Xinanjing Model for simulating small basin flash flood

摘要

This paper presents a modified Xinanjing Model for simulating the small basin flash flood. This model has 3 components, including evaporation component, which calculates the evaporation of the basin assuming the basin evaporates at its evaporation capacity for the whole period, the runoff production component, which calculates the runoff produced by rainfall and is similar to Xinanjing Model, and runoff routing component, which employs the one-sources runoff routing module to route the runoff. This model is employed to simulate the flash flood of a small basin with a basin area of 895 km~2 in southern China, and the result is satisfactory.
