Dear All,

I set up a hydrological model for my watershed, using Plant Growth Method for catchments. But I have a calibration problem.

I want to arrange my surface runoff for MONTHLY TIME SERIES. (As 'runoff resistance factor' for Soil Moisture Method). There is a 'plant uptake comp. factor (epco)' parameter can be used monthly, but it relates with transpiration.

Otherwise, must I change this method?

What is your advice? Thanks.
