Modeling non‐Fickian solute transport due to mass transfer and physical heterogeneity on arbitrary groundwater velocity fields

Abstract We present a hybrid approach to groundwater transport modeling, “CTRW‐on‐a‐streamline”, that allows continuous‐time random walk (CTRW) particle tracking on large‐scale, explicitly‐delineated heterogeneous groundwater velocity fields. The combination of a non‐Fickian transport model (in this case, the CTRW) with general heterogeneous velocity fields represents an advance of the current state of the art, in which […]
