What does "Multiplier" means in Hydraulic control structure BC?

Hello,I am a "EFDC 8.2 " user.I have set up hydraulic structure boundary conditions in the my model. The flow control type is “Flow derived from equation: Weir”.I am setting up the “Cell Options” but I don’t know what the "Multiplier"means.Please explain it to me. Thanks.

Sorry for not replying sooner. The multiplier simply adjusts the computed flows by this factor. It can be used in calibration if required.
