    I am modeling a pond in Pondpack (Pondpack v8i). The pond bottom is at elevation 1054 and 6ft to top of berm. I have a control weir at 1057 and riser at 1058. When i run the model, the output results show that 2yr, 10yr, and 100yr storm event at WSE of…

    Matt Baird
    Matt Baird
    When modelling a surge tank it is necessary to dictate the initial level. When the steady state conditions are calculated, this seems to not affect the surge tank initial level, even if it does not match the head at the point on the line where it is installed…

    Hi, thanks for your reply. You are correct; I am looking at the pipe carrying the water away. I have attached a basic sketch. I am modelling the pelton as a TCV followed by a D2A so I can have multi-stage valve control. Typically I would only be interested…

  • Hammer - Setting gravity

    Matt Baird
    Matt Baird
    Hi I am modelling a scheme which has a gravity lower than the standard 9.81 due to elevation. Is there somewhere in Hammer to set this, as surely the available energy will change?
