Below the box Watershed area, a new Scenario can be added. By adding a new scenario, it is
possible to simulate how the recipient is affected by changes within the watershed area (for
example after an exploitation) or in the recipient (for example, increased volume after dredging).
In Scenario 1, measured concentrations in the recipient can be specified. If
measurements are stated in Scenario 1, a corrected total concentration will be calculated for the
other scenarios. The corrected calculated total content (C,rec,corr) takes into account any over- or
underestimation of the calculated recipient concentration compared with stated measurements in
