meso-tidal coast

A meso-tidal coast is defined by a tidal range of two to four meters. These coasts are influenced by both wave action and tidal currents, creating a balance that shapes the landforms.12

Tidal currents play a significant role in transporting sediment, particularly in constricted areas like inlets and estuaries, where they can become quite swift. On the open coast, however, tidal currents are generally not strong enough to move sediment. Instead, the rise and fall of the tide distribute wave energy across the shore zone by altering water depth and the shoreline's position.1

The interaction of waves and tides on meso-tidal coasts can lead to varied coastal environments. While wave action is responsible for erosion and the formation of features like wave-cut platforms, tidal processes contribute to deposition and the development of landforms such as tidal flats. The specific landforms present depend on the relative intensity of these processes and the underlying geology.1345
