Dear WEAP users
I'm considering use Runoff / Infiltration ratio as a calibration parameter.
May someone tell me how to adjust runoff / infiltration ratio in WEAP data Schematic.
Thanks all !

Dear Quoc,

Which catchment methodology are you using, and where are entering data for a runoff/infiltration ratio?

Dear Stephanie
I used Runfall-Runoff model, I saw that follow this link, we can see "runoff fraction": Supply and resource \ runoff and infiltration and after that move to "from...", in tab inflow and outflow, we can see "runoff fraction", but I can not modify it, it default 100%. And I'm not sure "runoff fraction" is the same runoff/infiltration ratio. I just read "runoff/infiltration ratio" in some paper, they used it to calibrate model.

Dear Pham,

There are two Rainfall Runoff methodologies in WEAP - simplified coefficient method, and soil moisture model. Which are you using?

Are you looking Infiltration/Runoff Flow in the results section? I'm not clear where you are seeing the language about "fraction." Can you explain?
