Subject: Request for advice on climate change impact and model calibration in WEAP Posted: 6/10/2025 Viewed: 315 times
Dear WEAP community,
My name is Hikimat saadi , and I am a PhD student working on modeling the water balance of Lac de Guiers in Senegal using WEAP.
I would like to know Which function or approach in WEAP is most appropriate for assessing the impacts of climate change on water availability in a basin?
For example, I understand that to model (growth) in urban water demand, we can use the growth function - is there an equivalent or recommended approach for climate change scenarios? How do we approach the calibration and validation of WEAP models?
Thank you in advance for your suggestions. Your help will be invaluable in improving my model.
Yours sincerely
Mr. Doug Chalmers

Hello Hikimat,
The WEAP catchment delineation tool allows you to select future projected climate data from CMIP6. See the WEAP tutorial chapter on Catchment Calibration for more info on the catchment delineation mode. A detailed explanation of how to create scenarios of multiple climate projections can be found here: https://www.weap21.org/index.asp?action=9&read=4546&fID=30.
To learn more about calibration, the best resources are our catchment calibration chapter in the WEAP Tutorial. Particularly pages 221, 222-226, and 212 which show how to adjust your hydrologic parameters to achieve the desired results. Additionally, we have video lessons available on calibration on YouTube: https://www.youtube.com/watch?v=Notx1vfeRCk.
Hope this helps!
-Doug
