Beach Basics Coastal Care

Coarse sand or gravel on a beach absorbs much more of the wave swash and more water moves up the beach when a wave breaks than moves back down toward the sea. Less backwash means fewer sand grains moving back. In other words in a coarse sand beach the tendency is to move sand landward and pile it up in a relatively steep slope.

Clay minerals themselves are not sandforming minerals. They can not be because their size is not large enough to be considered sand.

Dust is present in many river and especially inland sand samples.
