I have run InVEST SDR model and i get output like total sediment export. Now i have problem with validation from where i validate model output values is there any specific field experiment we have to set or any other way to validate model in easy way. please rectify my query with immediate effect.
Thank you
Hi @Rajesh and welcome to the forum!
If you have not already done so, I would recommend taking a look at the InVEST User’s Guide for SDR, and specifically the Calibration/Comparison with Observed Data section. This section references a paper that gives more information.
In addition, if you search “validation” in this forum you’ll find posts that may be helpful.
Thanks!
i am forgot to tell you that which region i have apply this model there is no observed sedementation data and there is no or any other types of water gauge which record sediment export so for this region without any authentic source how i can validate model results ?
One possible approach for validating freshwater quality ecosystem service models in data-scarce regions is described in the study found at this URL:

This paper giving validation idea for NDR not for SDR ?
