GIS procedure for developing three-dimensional subsurface profile
Abstract
A geographic information system (GIS)-based procedure for developing subsurface profiles from well-log data is developed. The well-log data base is constructed from a series of borehole geophysical logs. Interpretation of geophysical and formation well logs is discussed. The GIS procedure is developed to target a modeling area and interpolate the well-log data base to create a three-dimensional representation of the subsurface environment. Any number of cross-sectional profiles or three-dimensional images of well-log data can be created and viewed interactively. From the generated profile information, a vertical discretization of the study area is defined. For each of the denoted subsurface units, a GIS-MODFLOW interface computes the geohydrologic parameters from the GIS well-log data base. The well-log data is analyzed and output in a format compatible with the input data structure of the ground-water flow model MODFLOW. An example modeling problem demonstating the range and versatility of the well-log data base and the GIS-MODFLOW interface is presented. © ASCE.
