Abstract：Groundwater flow system theory and numerical simulation technique are foundamentals in hydrogeology.Generalizing aquifer group is an important foundation for groundwater flow system analysis and numerical simulation,which directly affects the accuracy and the reliability of the simulation results.This paper proposes a new method named cumulative transmissivity to generalize aquifer group,aiming at improving the generalization accuracy and reliability.The new method is characterized by aquifer structure based on the changes of the accumulated transmissivity (product of hydraulic conductivity and its thickness) with depth and the integral characteristics of the hydrogeological profile.A case study in the Manas River basin is presented in this paper.Based on the generalization,a hydrogeological structure model is built using the GMS software and its TINS module.The results indicate that the aquifer structures generalized using this method have a high rationality and fidelity.The 3D model well displays the spatial distribution of the aquifers and auitards in the study area and provides a good foundation for groundwater flow model.
