Dear Narmin,

hello dear ms galaitsi
Itake the datas from the Iran national documents.
i want to calibrate the model first. but i do not know how to do it?

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?

hello dear Ms Galaitsi

I want to enter the evaporation of each crop for example wheat ,tomato, etc.

thanks alot.

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.
