TOPMODEL在韩江流域暴雨径流模拟中的应用研究
|
摘要
该文借助ArcMap与GRIDATB计算地形指数—面积分布函数,运用TOPMODEL模型对广东省韩江棠荆流域的暴雨径流进行研究,利用该流域1989—2004年的降雨、蒸发与流量资料,采用地貌参数法与人工调参法对其中的6场洪水进行模型参数的率定,使用另外的6场洪水进行模型的验证,并对影响模型模拟精度的因素进行了讨论。在参数率定期及验证期的确定性系数平均值可达82.05%和76.58%,结果表明,该模型可用于韩江棠荆流域的暴雨径流模拟。该研究成果对广东省中小流域的洪水预报具有重要的实际意义。
TOPMODEL is a semi-distributed model that incorporates the effects of hillslope topography and variable-source-areas.In this paper,TOPMODEL is applied for flood simulation to the Tangjing Catchment of Hanjiang Basin.By the use of Arc Map and GRIDATB software,topographic index and distance-accumulated-area curve have been extracted.Utilizing a total of twelve floods from 1989 to 2004,six floods are used to the calibration of model parameters,and the other six floods are used to the validation of model parameters.Finally,it's found that the simulation precision is well.The average coefficient of efficiency is 82.05% and 76.58% in these two phases.Based on the error analysis and evaluation of the simulation results,further discussion has been done to the reasons for causing error of model simulation.It is shown that the TOPMODEL model is suitable to the Tangjing Catchment.To the fact that local heavy rains occur frequently in Guangdong Province in recent years,flood disasters are becoming more and more serious,it has been put a certain of practical significance to the study of flood forecasting of small and medium-sized basin in Guangdong Province.
