How can I get the total discharge through a cross section, from a MIKE FLOOD simulation?

You can compute the discharge through a cross section using the Flood Modelling Toolbox. To achieve this, open a new Flood Modelling Toolbox from the MIKE FLOOD folder - see Fig. 1



Fig. 1 - New Flood Modelling Toolbox Option


  • The 2D result file can be loaded from the Results \ Cartesian Grid menu (for *.dfs2 result files) or from the Results \ Flexible Mesh menu (for *.dfsu result files) 
  • The 1D result file, if any, can be loaded from the Results \ River Results menu
  • The cross sections through which the discharge is to be computed have to be specified in a shape file, loaded in the Buildings/structures menu. The selected shape file may contain multiple cross sections, and cross sections may be made of polylines (not only straight lines).

See Fig. 2 for above.

From the left tree view, you can now go to the Flood Tools tab, and select the Discharge tool - see Fig. 3

From here, you can select the result files and shape file to be processed, and the output specifications - see Fig. 4


Pressing the Generate discharge button will create one time series (*.dfs0 file) per cross section.

Each time series will be named using the selected attribute from the shape file, and will contain, when relevant, discharge from the 1D model, discharge from the 2D model, and total discharge - see Fig. 5
