Abstract: The permeability heterogeneity of riverbed sediment significantly changes the spatial configuration, flow paths, and interfacial fluxes of the hyporheic zone (HZ) in riverbeds. Previous research on transverse hyporheic exchange in compound rivers primarily focused on processes driven by riverbed morphology under homogeneous conditions, often ignoring the effects of permeability heterogeneity (Geng et al. 2020). This study used a one-way sequential coupling model to examine the transverse hyporheic flow and solute transport under the impacts of layered heterogeneity in a conceptualized symmetrical compound channel.
