Table 4.6. Comparison between concentrations generated before and after change in code. The yellow colur indicate the combinations, where the primary source creating the highest concentration has changed from groundwater or drainage contributions to drift. The ratio between the maximum concentrations generated in the second and the first simulation is indicated in the table.
Tabel 4.6. Sammenligning mellem koncentrationer genereret før og efter ændringen I modelkode. Den gule farve viser de kombinationer, hvor den primære årsag til høje koncentrationer er ændret fra grundvandstilførsel til drift. Forholdet mellem maximums-koncentrationerne genereret i anden og første simulering er vist i tabellen.
