An investigation of the effects of model structure on model performance to reduce discharge simulation uncertainty in two catchments

摘要

This paper investigates the variations of model performance caused bydifferent model structures in both flow processes and model complexitylevel. Two case studies indicate that model efficiency is strongly dependenton model structure. The resulting substantial variation in both the modelefficiency and the hydrographs from different model structures is used toestimate the structural uncertainty. The results help to select the mostappropriate model adapted to local situations, which reveal great conformitywith the actual hydrological patterns in both study basins.
