Abstract
ABSTRACT An alternative structure with an up‐gradient permeable reactive barrier (PRB) and a down‐gradient cut‐off wall is proposed to enhance plume capture and degradation while optimizing material use. A 2D analytical model is developed to predict the contaminant transport through the dual‐domain barrier system. The proposed analytical solutions are verified by comparing their predictions with results from numerical solutions and from previously published 1D analytical model. The derived analytical solution is used to explore how the arrangement of PRB and cut‐off wall structures affects the system's performance. We show that the cut‐off wall domain can direct flow and reduce the contaminant flux through the…
