Which process primarily dictates sediment sorting along coastlines during longshore drift?

💡 Explanation

Hjulström Curve dynamics affects sediment sorting because the erosion, transport, and deposition of differently sized particles depend on flow velocity; therefore, coarser sediments deposit first rather than smaller particles that stay suspended longer due to weaker settling velocities.
