SWAT Toolbox does not display NSE,MSE, RMSE, PBIAS

[Alfa Essossinam]

Hi guys, I need a hand on this matter I am facing with SWAT Toolbox.

After runnig the model, the SWAT+ check did not display some thing nice as you can see below.

I went on to visualise so I can start readjusting the set up or go for the calibration. Unfortunately when I  load my observed data, it shows, however the NSE, PBIAS displays NaN, the sensitivity analysis and the calibration does not give any results. 

I REMEMBERED TO CHANGE THE DATE FORMAT

The versions of the tools I am using are:

QGIS 3.28.15

QSWAT  2.7.4

SWAT+ Editor 2.3.3

SWAT Toolbox  1.0.5  (install using swatplus-toolbox-v105-installer)

I am working on the Mono River Basin, transboundary, shared between Benin and Togo.

Best regards

Hello,

Usually, the toolbox shows NaN when our simulation period does not overlap with the observed data. However, I can see that your simulation period clearly overlaps with the observed data time period. Another reason could be that while selecting outputs, we might miss selecting channel - daily output as below.

If this doesn't work, I am not sure of the next steps.

Besides that, I am curious about the water balance you have obtained. I can see that there is a huge amount of surface runoff and very little return flow and interflow. May I know if your basin is urban-dominant (your curve number is also high)?  I am getting a similar water balance even though my basin is agriculture-dominant (my water balance is attached below).  

Thanking you,

Revanth M.
