Network inconsistencies management

When saving the network before running the mesh generator TALWEG, the application performs consistency checks on the network. The errors are of two distinct levels: - Warning: the inconsistencies found does not prevent the mesh generator and the simulation from running, but the network entered does not match the requirements for using the software in good conditions. - Error: the inconsistencies found prevents the generation of a mesh by TALWEG.

A click in the “Correction” column opens the window where the error can be fixed.

Main errors

Here are the most frequent error messages : - Locations should be monotonic within the reach. - The space step cannot be nil (otherwise a default value 100 m will be chosen). - Major Section offset must be between min and max offset of Minor or Minor/Medium Sections. - Distance of first Major Section (in order of increasing offsets) must be null. - At least two Major Sections. - Major bed should hold at least two Major Sections with distinct offsets. - Distance of last Major Section (in order of increasing offsets) can’t be null, or another Major Section should follow with a distance >0. - Beginning and end abscissas of the reach are similar. Length of Reach can’t be null. - There is at least one loop in the network. - Network is splitted. - There is a loop in the branch. - Branch is splitted or is not linear. - Pond elevations at Node must be monotonic.
