3D spatial dispersing method for interstitial geohydrology succession based on GIS

This paper aims at obtaining the furthest assurance of the unitary of interstitial geohydrology succession(IGS) types in discrete voxels,improving on the defect of multi-types of current simulating discrete voxels,and consequently,enhancing the operability of parameter evaluation and the precision of simulated result in the stimulating process of groundwater current 3D finite-difference.Considering spatial discontinuity and thickness asymmetry of IGS in the nature,this paper studies IGS 3D spatial discrete techno-course based on geographic information system(GIS) and put forward the implementary method with IGS anomalous hexa-voxels.It can not only keep the type unitary of IGS anomalous hexa-voxels to the utmost extent,but also make full use of GIS spatial analysis and data auto-extraction functions,extract rapidly the spatial coordination of all calculating labels and all kinds calculating parameters,therefore,greatly shorten the time need in geohydrology model spatial dispersion and relative data file management,and increase the simulating effectiveness for a given period of the groundwater 3D finite-difference.
