zhydrograph

Hi,

I'm modeling a river arriving in a lake. When I have an inflow of 200m3/s I know that the outflow is at 430.5 msm. I have used a fixed water surface elevation with the intflow defined by a zhydrograph. I'm suprised because at the begining I have the following results:

TIME =  1.000003e+002    hyd. Time Step =   3.133820e-003
Qin[1]      = 2.000000e+002 [m3/s] (Inflow)
Qout[2]     = -1.100002e+003 [m3/s] (Outflow)

Is it because I have a dry initial condition? This means that there is water inflow from dowstream to upstream and after a certain time the water would go in the other direction?

Thank's for your help. Best regards

Re: zhydrograph

Hi Quentin,

did I get you right: your INflow is a zhydrograph?

[...] with the intflow defined by a zhydrograph [...]
