Blackphoenixz Posted August 17, 2019 Report Share Posted August 17, 2019 Hello Everyone I have a issue with defining inflow rate to related cells. I have the total volume of inflow for each month (i want make a time series general head), but i dont know how i should define the head of the 2 points of inflow line & amount of conductivity correctly. (for example the volume of inflow is 110 MCM & the length of inflow line is 97 KM and Average elevation of area is 1900 m) If anyone can help me it would be great.

Michal Posted August 19, 2019 Report Share Posted August 19, 2019 (edited) Hi, I think what you are trying to achieve could be done only aproximately, because you only have to assume what the head in the model will be. Anyway, for a given cell Qb = cb (hb - h), where Qb is the flow into the cell from the source cb is the conductance between external source and the cell hb is the head assigned to the external source and h is the model calculated head in the reference cell You problably have measured hb, so I would calculate cb this way: cb = Qb / (hb-h) But as I said, you can only assume what the value of h will be. Maybe calibrating the model against the measured flow could be a better practice. Edited August 19, 2019 by Michal Quote Link to comment Share on other sites More sharing options...
