Dear Hanan,
Are you asking about linking the supply to the demand? In this case you can use a transmission link. Just make sure that when you build it, you start from the source (the river or canal) and end at the destination (the demand site).

Dear Stephanie
I have a problem in WEAP calculation for the agriculture catchment demand, I choose , Irrigation Demands Only Method, The input catchment data is as following: Area served percentage of each crop sharing are(total number of crops 5 crops sharing in summer season 100% and another 5 crops in winter), Kc, ET ref, losses
The problem the results estimated zero demands in some catchments and not reliable value for the others.
I afraid from the percentage of sharing area writing form (eg. 7.5% is write direct 7.5 or 0.075), the second the total percentage of area served in winter and summer season, it entered 100% for each season. Is that make a conflict in calculations.

Dear Hanan,
If the unit says "percent", you can write 7.5 instead of 0.075.
In terms of the demand, its possible to have no demand. This happens if there is more rain than water demand (according to the parameters for the characteristics that you listed above). If you believe your climate record is good, then I would suggest altering the parameters for these characteristics to try to increase the demand for the catchment.
