C.7 Instantaneous mass flux entering a groundwater layer

The instantaneous mass flux entering a groundwater layer from above has the following properties:

• Content:
  • Reports the temporally and spatially varying instantaneous flux of pollutant mass entering a groundwater layer from above
• Name:
  • “GW Layer <Layer number> MZ <pollutant_name>”, e.g. “GW Layer 2 MZ SED_FINES”
• Units:
  • See Section 4.5.3.3.3 and Table 4.1, “Map output concentration” column. These units are multiplied by cubic meters per second and reported in this MZ layer

Depending on model configuration, these fluxes may be ‘noisy’ given their instantaneous calculation. Time integrated equivalent quantities are therefore additionally provided (see Section C.8). One field is produced for each groundwater layer, and labelled ‘…Layer X’, where X is the layer number.
