osaillof 0 Report post Posted January 21, 2016 Hello TUFLOW community, I am trying to model a tilting weir using the latest version of ESTRY-TUFLOW... with a series of operation rules enabling the weir to raise by intervals of 100mm every time the 1D flow downstream is reaching a specific value. Has anyone got any examples on how to represent this structure? Kind regards, Oli Quote Share this post Link to post Share on other sites
osaillof 0 Report post Posted January 26, 2016 Further to my post above, I have found examples of 1D network files and operation rule that seem to approximate the operation of the above tilting weir (based on a set water level not flow downstream). A culvert with vertical overflow gate (using the NAIR 2003 method) OR a gated spillway (using the USACE 111-21 method). See examples attached. Could anyone recommend the appropriateness of each method in relation to the aforementioned tilting weir?
