Please help me anyone... I have irrigated areas which I have tried to enter into the model. For one I have 0.27 Km2 I try to put it in but it only allows as percentage of total catchment area. Now I convert it to get 0.061% when I put it in and hit result it says that irrigated areas can only be 0 or 100 percent. Please help

Hi Darlington,

There's an example of this in the WEAP tutorial chapter about hydrology. We suggest disaggregating your land use types into irrigated and non-irrigated areas, eg. Forest, barren land, irrigated area. You could even have an area for rice irrigation, and another area for fruit, according to the needs of your model.

Once you have disaggregated the catchment area (following the instructions in the tutorial), you can say that your irrigated area is 100% irrigated.
