Linear Inflows
Linear Inflows
(OP)
I am trying to model a river flooding into my project. I have the gage data for the river's elevation vs. time, but I'm having trouble trying to set that as a flow input for my unit. I'm looking to set either a subcatchment or pond that has a linear increase in elevation with respect to time to feed the spillway coming into my unit. I've tried modifying the rain and UH distributions, but it isn't providing the characteristics I need. Any thoughts on how to create this model?

HydroCAD needs an inflow hydrograph (flow vs. time), which is used to do the routing calculation. You can't enter elevation vs. time, except in a link, and that's only for used to define a variable tailwater.
You may have to do the weir calculation separately in order to produce an inflow hydrograph for your HydroCAD model. However, this is pretty easy if you use a weir stage-discharge curve generated by HydroCAD.

I don't know within the computational engine of HydroCAD if it would take much tweaking to allow a link to serve as an input, but it would be handy for our large river and coastal work. Maybe version 10.5???
Thanks for all the prompt assistance.
