Becoming shallow gradually.

The increase in the wave height of wind waves in shallow water because of the divergence in wave group velocity. This happens when the depth decreases near the coast.

shallowing or rising

Deposition of sediment causing a waterbody or location within a waterbody to become more shallow.

Said of an ocean or lake bottom that becomes progressively shallower as a shoreline is approached. The shoaling of the ocean bottom causes waves to rise in height and break as they approach the shore.

Changes in wave height as waves move into shallow water. Except for a limited depth region, shoaling increases wave heights. Shoaling occurs even if wave heights and directions do not change as a result of wave refraction.

Becoming or making gradually shallow.

A phenomenon occurring as the waves enter a shallow water - their movement forward is slowed down because of the bottom friction, and thus their height increases.

The process of a waterway becoming shallow due to the deposition of sediment.

The influence of the seabed on wave behaviour. Such effects only become significant in water depths of 60m or less. Manifested as a reduction in wave speed, a shortening in wave length and an increase in wave height.

Deposition of alluvial material resulting in areas with relatively shallow depth.
