Project overview: Application of “multiple-point” geostatistics on modeling groundwater flow and transport in heterogeneous environments with complex geological structures

Introduction: State-of-the-art in characterizing heterogeneity in complex geological environments
Sedimentological and erosional processes often result in a complex three-dimensional subsurface architecture of sedimentary structures and facies types. Such complex sedimentological heterogeneity may induce a highly heterogeneous spatial distribution of hydrogeological parameter values in porous media at different scales (Klingbeil et al. 1999) and may consequently greatly [...]

Paper: Application of multiple-point geostatistics on modelling groundwater flow and transport in a cross-bedded aquifer (Belgium)

Abstract
Sedimentological processes often result in complex three-dimensional subsurface heterogeneity of hydrogeological parameter values. Variogram-based stochastic approaches are often not able to describe heterogeneity in such complex geological environments. This work shows how multiple-point geostatistics can be applied in a realistic hydrogeological application to determine the impact of complex geological heterogeneity on groundwater flow and transport.

Paper: Relating small-scale sedimentary structures and permeability in a cross-bedded aquifer

Abstract
The objective of this study is to investigate the relation between small-scale sedimentary structures and permeability in the Brussels Sands formation, an early Middle-Eocene shallow marine sand deposit in Central Belgium that constitutes a major groundwater source in the region. A field campaign was carried out consisting of field observations of the sedimentary structures and [...]
