摘要
为了探索无资料流域的洪水预报问题,以改进的HBV模型为例,介绍应用地貌参数法推求无资料地区模型参数的方法。并利用武江流域实测50场雨洪资料,对改进的HBV模型进行率定,在参数达到较好的模拟效果后,与流域的地貌参数建立相关关系,然后利用所建立的相关关系及武江支流田头水和韩江支流丰良河的地貌参数,推求模型参数,最后用田头水和丰良河各50场洪水进行验证,取得了较好效果。
In order to study flood forecasting in the ungauged area,it described the calculation of HBV model parameters for the ungauged area using geomorphic parameter method.The 50 flood events data in the Wujiang River Basin were used for calibrating the HBV model parameter.After that the parameters reached better simulated effect,correlation was established between the model parameters and the geomorphic parameters.Then the correlation and the geomorphic parameters of the basins of Taintoushui and Fenglianghe were used to calculate the model parameter.At last,verification was made using 50 flood events respectively in the basins of Taintoushui and Fenglianghe,and a good result was achieved.
