It is verified by the observed data of Xianing Port Area in Changsha City that the model is of high accuracy, with the greatest relative error of the peak flow of only 7.85%, thus can be used in runoff simulation of harbor rainfall drainage system.

• 经长沙市霞凝港区的实测资料检验，证明该模型在港区小流域的雨洪分析中有较高的精度，洪峰流量最大相对误差仅为7.；85%25，可用于港区雨水排水的径流模拟。
