Dear All,

We have been working on the WEAP model. Since our basin area is quite large and we are using 10 climate models from CMIP6, we set up two separate models: one for the historical period (1980–2014) using Princeton climate data, and another for 2015–2060 using CMIP6 climate data. By using key assumptions, we handled the 10 climate models as scenarios in the second model. The model setup was carried out through automatic catchment delineation.
However, calibration has become very time- and energy-consuming. Is there a possibility to do everything in one model? If so, how can we handle the climate data from Princeton and the CMIP6 models for the years 2080 to 2060 in a single model? How should we manage the base model and the scenarios for the 10 climate models? I would appreciate any help regarding this.

Mr. Doug Chalmers

Selam,

Yes, you can certainly organize both historical and future climate into one model. Look in the WEAP Help for ReadFromFile and you can see you can use "YearOffset". Enter in the number of years to shift for YearOffset to switch either the historical or future climate projections into the years simulated by your model under General --> Years and Timesteps.

Hope this helps!
