Release notes v17.2.2

  • 17 May, 20178 September, 2021

Automatic summation of annual flows, loads and concentrations of pollutants from selected (sub)watershed areas with or without treatment.

From the flowchart can now be chosen to have no treatment in the selected sub-drainage area (set as default when new project is started).
If you work with different sub-basins in the same file, where some areas have treatment measures and others do not,
or where you divide a detail plan area into smaller parts and where some part areas diverge to treatment and others do not, you can now automatically summarize annual flows, loads and concentrations of pollutants from selected sub-basins or sub-areas (all these are treated as sub watershed areas A1, A2, ..).
This choice is made in the MR-report where you click on the areas to be summed up. The results are presented in tables in this report.

(The function only works in projects started after 2017-02-20 where it is linked to the update “Unique treatment facilities per Subarea”)
