  • Descrição: •9 interpolation methods for a Jurassic karst & a Quaternary alluvial aquifer are compared.•Calculated inter-aquifer exchange rates vary greatly depending on the chosen method.•Plausibility was additionally validated with eco-hydrogeological data (e.g. wetlands).•Best results achieved with co-Kriging incorporating additional data, e.g. topography. The selection of the best possible method to interpolate a continuous groundwater surface from point data of groundwater levels is a controversial issue. In the present study four deterministic and five geostatistical interpolation methods (global polynomial interpolation, local polynomial interpolation, inverse distance weighting, radial basis function, simple-, ordinary-, universal-, empirical Bayesian and co-Kriging) and six error statistics (ME, MAE, MAPE, RMSE, RMSSE, Pearson R) were examined for a Jurassic karst aquifer and a Quaternary alluvial aquifer. We investigated the possible propagation of uncertainty...
