These studies suggest that beach sand primarily comes from rivers, coastal cliffs, eroding coastlines, and marine organisms, with contributions varying by location.
Beach sand is a complex mixture of mineral grains originating from various sources. Understanding the provenance of beach sand is crucial for effective coastal management and environmental conservation. This synthesis examines the origins of beach sand based on multiple research studies.

Shelf and Offshore Contributions:
Human Influence:
Beach sand originates from a variety of sources, including rivers, coastal cliffs, marine organisms, and offshore sediments. The specific composition of beach sand is influenced by the geology of the source rocks, hydrodynamic processes, and human activities. Understanding these sources is essential for managing and preserving coastal environments.
