Hi,
I have a basic query regarding the input of ET Ref values in WEAP. I am not sure if the monthly average value (eg. 2mm/day) has to be used or the monthly total (eg. 60) has to be used. I am confused whether WEAP uses the value as it is or computes the sum for the monthly time step during the model run.

For the Rainfall Runoff (simplified coefficient method), ET Ref should be entered as the total ET Ref for the month (e.g., 60 mm/month), not the daily average (e.g., 2 mm/day).
