Tools and methods constructing 3D geological models in the urban environment. The Paris case.

Abstract : Building a geological model for an urban environment is a relatively difficult task, because of: (1) the heterogeneous and commonly poor quality of the data; (2) the high spatial variability of the formations to be modelled, the relevant slice of ground for the planner being located at surficial formation level (fluvial alluvium, for example); (3) the necessity of handling a very large amount of data (several thousand drill holes); and (4) the fact that most of the data provide inequality constraints for the tops / bottoms of the layers to be modelled. Here we present a set of tools and methods designed and tested at BRGM over the past few years for (1) performing automatic consistency checks before and during modelling, and (2) facilitating the building of geological models that, in particular, take geological rules and inequality constraints into account.
