If the data is unavailable how to enter the net evaporation data for a reservoir. I have entered the volume elevation curve, so is it possible to calculate the net evaporation data in the reservoir through weap.

Dear Prakhar,

Some of the catchment models, like the soil moisture model, will calculate evaporation for you. To use that result, you'd have to use the previous time step value (this is true for using any result in WEAP). It generally is not very direct translation, since it's for a soil moisture model. I find usually it needs to be multiplied by a factor, based on your understanding of the system.
