Based on the user manual, RES_PVOL parameter represent the volume of water that is needed to fill the reservoir to the principal spillway (x 10^4 m^3).
Why in the SWAT Edit Reservoir Parameter Window, there is a warning pup up, which mention that RES_PVOL should be >= 10 and <=100
In my case, I have RES_EVOL of 503 x 10^4 m^3 but I can't inserting a value of 480 in the RES_PVOL cell.
Can anybody help me with explanation please?
Thank you
