ABSTRACT

The detailed modeling of sedimentary media (alluvial sediments, deltas, etc.) that form
important aquifers is very complex for two reasons. The first is the intrinsic natural
heterogeneity of the geological medium and the second is that the data management
tools (manipulating geological and hydrogeological data) needed to implement them in
the hydrogeological models are not developed enough.

The paper presents a software platform containing methodologies and tools that
facilitate the integration of the 3D geological models in sedimentary media into the
hydrogeological modeling of flow and contaminant transport. This is composed by a
geospatial database and a set of tools allowing accurate stratigraphical analysis. The
geospatial database is used for the management of a large amount of different data types
coming from different sources (geophysical, geological, hydraulic, and others). Its
structure allows storing accurate and very detailed geological core description that can
be straightforwardly generalized and further upscaled. Currently the following tasks are
developed: (1) application and development of 3D geological techniques to characterize
the sedimentary media; (2) development of techniques for hydraulic parameterization
using a sedimentary media geological model; (3) generation of 3D hydrogeological
models, and (5) application to the Moesic aquifer system focusing the Bucharest city
region (Romania).
