sn3500 0 Report post Posted April 17, 2019 Hello, I am trying to model a breach of a wall that is triggered by a set WL up the wall of 18mAOD. The berach then lasts for 18hours, then is closed after that time, with the collapse and rebuild of the wall taking 1 hour each. Could you please confirm that the attributed I have assigned will replicate this situation please. Shape_Opti = TRIGGER Trigger_1 = A Trigger_Value = 18 (presume this is mAOD, and not m above ground level?) Period = 1 Reinstate_Interval = 18 Reinstate_Period = 1 Many thanks in advance.
