What is the maximum resolution of datasets that can be entered in WEAP model? what is the format? I am planning to use WEAP-MABIA for irrigation water requirement.

Dear Hamizah,

Do you mean spatial or temporal resolution, or something else?

Hello,
for spatial resolution. say for example 1km resolution precipitation dataset
Thank you for the reply

For spatial resolution:
There is nothing in WEAP to stop you from making a model of the whole world - but of course that doesn't mean that it's a good idea. I would say, figure out what questions you're trying to answer, and determine your spatial resolution to answer those questions. Often the WEAP areas are a catchment and its demands.

For temporal resolution:
This concerns the model timesteps, eg if you're looking at daily demand values/daily precipitation data, or monthly demand values/monthly precipitation data. The longest timestep you can have is a year, and the shortest is a day.

Keep in mind that your spatial and temporal timesteps are not independent. WEAP considers that the water travels through the entire course of the model in a time step, so you wouldn't want to use a short time step to model a huge area.
