However, as we will see in this unit human actions affect the state of equilibrium within the coastal system. The coast can be seen as a system in order to help to understand the processes and interactions involved. waves are not powerful (for a significant part of the year) the rate of deposition exceeds the rate of erosion. The topography and shape of ocean basins and nearby land also influences ocean currents. They do little to work with nature and sustainability is a key issue with them, despite their initial signs of success. bay. Coastlines of Emergence. Coastlines of Emergence.

Like most engineering schemes in geography, there’s hard and soft coastal engineering. bay, concavity of a coastline or reentrant of the sea, formed by the movements of either the sea or a lake. Friction with the sea bed as waves approach the shore causes the wave front to become distorted or refracted as velocity is reduced. Depending on the location, coastlines can be categorised as high energy or low energy.-High energy coasts are usually characterised by:-Strong wave action, typically during the winter months-The rate of erosion usually exceeds the amount of material that is depositedMain features usually are big cliffs and headlands.
