Subject: Calibration method focused on administrative boundaries   
Posted: 1/7/2024 Viewed: 487 times
I wish you a Happy New Year 2024. I am considering the possibility of calibrating the WEAP model using a calibration method focused on administrative boundaries and excluding the watershed. I have already included historical data of observed river flows in the supply and resource section, but the simulated flow is not being generated. Could you please share any insights or suggestions you may have on how to resolve this issue? I would also appreciate any information about other possible methods for calibrating my model.Thank you for your help.

Apologies for the slow response. A couple of notes to help you-

When you included observed historical data, did you input this into a streamflow gauge object? If so, streamflow gauge objects only serve as a comparison tool to calibrate modeled flows versus observed flows. You can see these comparisons in Results --> Supply and Resources --> River --> Streamflow Gauge Comparison. To input modeled flows into your schematic, you can go to your river object and enter in Headflow, or enter Surface Water Inflow to the river reaches.

For calibration, it is important to generate your flows with a subcatchments which have boundaries ending immediately at each streamflow gauge you are calibrating to. In other words, you want WEAP to calculate your flows that would occur precisely at the streamflow gauge location.

For more information on calibration, please visit our WEAP Tutorial chapter on Catchment Calibration (https://www.weap21.org/Tutorial) or visit our WEAP Youtube channel for a video on calibration: https://www.youtube.com/watch?v=Notx1vfeRCk&list=PLoJ3pxCzMP1uQRaimYV-wxJRRuIMNzdVU&index=17).

Hope this helps!
