GloPrSM v1.0.0 (IJ_QFL). GloPrSM is calibrated on modern river sand; beach sand in the same watershed is a reasonable proxy but not identical.
Got a close-up photo of the sand here?
Take a picture with a coin for scale and send it over. We're building a global grain-photo library and this beach isn't in it yet.
