Dear Sir/Madam,
i am working on a mountainous watershed, i just start WEAP project, In my watershed all agriculture is rainfed, no irrigation. Now my query is that either i will put demand sites for agriculture or not. I am confused about it. Any help must be appreciated.
Thank you!

To implement rainfed agriculture into WEAP-

You would use a catchment object, which would have a branched area for rainfed agriculture. The catchment delineation mode contains built-in data to populate the land cover. For rainfed agriculture, simply leave the "Includes Irrigated Areas" box unchecked for the catchment. The catchment will not need a transmission link and will simply only use rainfall and soil moisture within the catchment to attempt to supply ET demand for the crops.

Apologies for not answering this questions originally.
