Sedimentary media analysis platform for groundwater modeling in urban areas
In Europe numerous urban areas are located in the flood plains of the rivers. Sedimentary media (alluvial sediments, deltas, etc.) form particular frequently occurring environments within these valley fills. However, sedimentary media are normally significant aquifers due to their high permeability, storage capacity, interaction with surface water, etc. A reliable management of the hydraulic resources in urban areas can be performed only by using modeling. The models can provide accurate results if they correctly reproduce the hydrogeological processes. Tools and methodologies should allow the representation in three dimensions of the geological record heterogeneity and of its spatial distribution as well as the interaction of the groundwater with the urban infrastructure. The paper will focus on the main aspects of these instruments, which are currently developed within a national research project, that have to support 3D hydrogeological modeling. Within this project a software platform has been developed 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. An application of this platform is currently developed for the Moesic aquifer system (Bucharest city Region).
