Validation of Water Yield model.

Dear NatCap Staffs and members, 

I am using water yield model. I would like to know how do i test the model accuracy? Is there any verification method? 

Sincerely,
Shikshya

    Hi Shikshya -

    Check out this paper by our hydrologist Perrine Hamel et al, which does calibration, sensitivity and uncertainty assessments on the annual water yield model:

    In general, we compare the results of the model with observed data at a particular stream point in the watershed. You can either run the model only on the watershed draining into that observed data point, or use Zonal Statistics to aggregate per-pixel water yield results to the watershed draining into the observed data point. This paper will give you a lot more information about the whole process.

  • Thank you so much Stacie. I will go through the paper.
