I’m having some trouble with the DL Breach function in HECRAS. I’ve set up the physical model parameters for my embankment and checked the parameters are all within normal ranges.
The piping failure is initiating – in the results it shows the breach getting to the initial piping width but not progressing any further that that.
In the run, the following text appears in relation to the breach:
” 2D Unsteady SWE-ELM Equation Set (faster)
Breach at _Emb at 01JAN2000 00:01:00
Collapse of enbankment top due to vertical forces”
Could anyone provide some advice around what might be happening in the background here? Why is my embankment not breaching?
Thankyou
