TheParameter Uncertainty Analysis Of The HYMOD Model

Firstly, global water crisis is talked about to lead to the topic of the importance of hydrology model research. The hydrological model uncertainty is focused on in the next part.The research part of thisarticlechooses the data of the Xiangxi River, using GLUE method to analysis the parameter uncertainty of the HYMOD model.This article discussed the advantages and disadvantages of the method, and then selected GLUE method of multi-criteria likelihood function to discuss the parameter uncertainty of the model.The advantages and disadvantages of the improved GLUE method were analyzed aswell.The influence of changing the weight of these likelihood functions to the result was discussed too.Finally, the last part of this essay are conclusions and some prospects.
