Fig. 15. Contour of the predicted groundwater level (light lines) and flow velocity vector fields on the water table in October 1999 for the refined model in (a) the entire model domain, (b) in the vicinity of the B7 trench, and (c) in the vicinity of the B53-B58 trench. Note that the contaminant plume contour lines are indicated by thick lines (for scales, see Fig. 13).
