Dear Narmin,

What kind of evaporation data do you have? Where is the evaporation coming from?

Dear Narmin,

First you will need to enter your data and then calibrate the model. Evaporation data can be entered in reservoirs (net evaporation) and within the simplified coefficient method (ETref). In the rivers you can enter evaporation data as a percent of flow.

Which evaporation data are you looking to enter?

Dear Narmin,

You can enter ETref (reference evapotranspiration data, under the Climate tab) for different crop types using the Simplified Coefficient Method for your catchments. See the Hydrology module in the WEAP tutorial (www.WEAP21.org/tutorial) for details.

The MABIA method for catchments also allows you to enter or calculate ETreference data.
