考虑上游中小型水库影响的北方地区洪水预报方法研究
Study on method of flood forecast in northern region considering the impact of medium and small reservoirs of upstream basin
摘要
Abstract
The existence of many medium and small reservoirs in the river basin changes the original process of runoff generation and confluence , which has more obvious impact on the arid and semi-arid re-gions of northern China .On the basis of DHF hydrological model which applied to the northern arid and semi-arid regions , this paper quantitatively estimates the capacity of runoff interception of medium and small reservoir swarm according to the data such as antecedent precipitation , evaporation , control area of small reservoirs , beneficial reservoir capacity , and some others;Considering the varied influences of me-dium and small reservoirs swarm on the flood confluence process of different soil moistures , distribution of rainfall and different cumulative rainfall ,and then it built the improved DHF model and applied it to Men-lou basin of Yantai .The simulation results show that the improved DHF hydrological model can effectively improve the accuracy and qualified rate of Menlou reservoir flood forecast and can provide scientific basis and technical support for reservoir flood control operation .关键词
