Abstrakt

We examine the feasibility of combining the complexity of the developing sedimentology of the floodplain aquifer system with the complexity of the network of the most probable controlling geochemical reactions derived from a 1D PHREEQC model—in a “4D” model of the geochemical evolution of an aquifer that changes geometry over time—using PHAST as the modeling tool. It is shown that the combination is feasible in simplified narrow 3D sections and the approach is capable of generating distributions in groundwater arsenic concentrations that resemble the observed very heterogeneous spatial distribution in arsenic concentrations in flood plain sediments.
