Release notes v15.4.3

– In the model Runoff you can now add more areas in the same project.
Click on New Area to add a new area. Previous area values are copied to the new area.
You can also give the new area a name to easier have control over which area you are working with.
Go into the form (Sub)watershed area and add a name into the field next to the title
(Sub)watershed area.
Only 20 characters are allowed in this field. Click Save.

– Report 3 Pollutant transport adjusted.
The following has changed:
Pollutant concentrations (ug/l) per land use with stormwater+base flow without treatment.
Pollutant loads (kg/year) per land use with stormwater+base flow without treatment.

These are in the current situation limited to show only 20 substances due to a formatting
problem with the PDF conversion. The HTML version shows every substance.
This will be corrected in the future.

• Bio filters, macadam ditches and grassed ditches/swales implemented in the box.
• Equations added to the text descripitions of the flowchart data.
• Performance Report also as HTML enables copying selected tables to Word reports.
• Revise the function of “Studied” flow at low and high proportions.
• Multi-areas. Several areas can be handled in the same file, and tables of pollutants from several areas or areabefore and after exploitation are obtained in a new result report.
• Updates and revisions of calculations of flow and concentration and groundwater area at surface waters upstream in the sub watershed area.
• Red warning about too small ponds (pond bottom at least 2.0 m).
• Add a function with max inflow to flow detention facility.
• Justify max rain duration at design flow detention with red warning symbol if the volume is increasing all the time.
• The result report is supplemented with various design flows and flow detention volumes at different durations.

January 2016

• Be able to set different rain intensities (l/s/ha) for different durations for the selected return period so you can use the model all over the world.
• The result report is supplemented with table of pollution load (kg/year) broken down by
land use.
Add the design of underground basins with or without macadam or filters.
• Relocation of the input rainfall depth to Box Precipitation from the box Wet ponds.
