Study on Inverse Evaluation of Parameters Based on Groundwater Numerical Modeling

The hydrogeological parameters were evaluated inversely by manual parameter adjustment,zone dividing and point input parameter adjustment methods,based on the GMS groundwater numerical simulation.These three inverse evaluating methods had been comparatively analyzed,which showed that zone dividing parameter adjustment method based on manual adjustment possesses higher precision and better fitting to the actual hydrogeology condition.The instance results show that these three methods on hydrogeological parameters are all practicable.
