Estimates of dispersivities by the interpretation of statistically anisotropic filtration velocity vectors in fluvioglacial aquifers

The stochastic approach was applied to several fluvioglacial aquifers of different scale in southern Bavaria, Germany, and northern Switzerland, where filtration flow vectors were measured by point dilution techniques using 82Br as a tracer. Using typical log velocity covariance parameters, the effective hydraulic conductivity tensor and the ultimate dispersivity tensor are estimated
