Hi!
I am using rainfall Runoff soil moisture method of WEAP modeling.
I modeled my irrigation demand as a watershed demand by designating the sub-catchment as containing irrigated land cover fractions and connected the sub-catchment to the river using a transmission link.

I have three different irrigation schemes in the sub-catchment at different locations. But based on the above modeling approach they are merged together as irrigated land cover branches not as separate irrigation schemes. Hence, during my analysis I couldn’t assign different irrigation efficiencies for the three different schemes.

So my question is when modeling irrigation demand as a watershed demand, how can we disaggregate the irrigation demand to different schemes/zones so that we can define different characteristics for each scheme.

Thank you!
