Fig. 1. Schematic representation of the four situations that are modeled: (a) Laboratory incubation set-up commonly used to study lugworm bio-irrigation; (b) Lugworm bio-irrigation interfering with groundwater seepage on a tidal flat; (c) Pore water flow i
Fig. 2. Model [1]: lugworm bio-irrigation in a laboratory core set-up. (a) scheme of the sediment domain geometry and the finite element mesh; (b) simulated flow line pattern; (c) simulated concentration pattern for the conservative tracer bromide after tw
