Massive Coastal Erosion and Landforms.

What are coastal landforms?

Landforms are forms of land that occur on the coast. A Landform is a unique element in the ground. A landform is a natural element on the earth’s surface, like a mountain or a river. Coastal erosion and landforms is highly searched keyword in the coastal areas. The term “coastal landform” refers to the coastline landform, also known as a beach landform, which is a characteristic of the land formed by erosion. It usually refers to landforms created through water erosion like waves. This kind of erosion is exacerbated at times by winds.

 Landscapes of the coast are created through the presence of a variety of coastal landforms. Some examples of coastal landforms are coves, bays, cliffs, and caves. Coastal landforms differ from other landforms since their principal eroding agents are sea waves and ocean waters. Although wind is an element of coastal landforms, it’s not the sole reason for their erosion.

The types of coastal Features

The landforms that make up the coastal erosion and landforms features are those of coastlines and coastal plains. What exactly is an oceanfront? It is the line that separates the ocean and the land. The landforms along the coastline include cliffs, caves, coves and headlands, bays, and more.


One of the many coastal landmarks is the Cliffs. A cliff is an area of a seawall that has been slowly destroyed by the waves. The lower part of the wall is being eroded while the top portion is there. When the top layer of rock is fragile, it begins to weaken. As it sinks, a cliff can be formed.

Cliffs are usually formed through the erosion of waves. Some examples of cliffs are:-

  • White Cliffs of Dover
  • Rupal Flank of Nanga Parbat
  • North Esplanade in California


A cave is formed similarly to a cliff. But, the walls of the cave remain in good condition. The caves are connected to a variety of different natural features of the coastal erosion and landforms, including arches as well as stacks and stumps. Suppose water runs all into the cave such that the entire inside of the cave is being eroded, creating an arch. In time, the top portion of the arch would become weak. It will fall. This results in the creation of an edifice. When and if that top layer of the stack gets removed, a stump is created.

Coastal Erosion and landforms


Coves are yet another feature of coastal erosion and landforms. In contrast to other coastal erosion and landform features, the rock closest to the shore isn’t the rock that is being eroded at the fastest speed. Instead, the water moves through the outermost rock, which is more durable. This rock is stronger than less slender rocks. It is the result that an enclosing wall of solid rock surrounds an area with water. The part that is exposed is referred to as a cove.

Examples of coves include:

  • Anacapa Island, California

Bays and Headlands

The two final coastal features of this area are headlands and bays. They are connected to each. However, they are not identical. Bays form by the interaction of waves with soft rock bodies. Sandy beaches are usually found in bays. They are usually in the form of an arc. They’ve been eroded away by the sea.

Some rock bodies that are harder than others are destroyed by waves from the ocean. However, the physical impacts of the water on these rocks are not as severe. Thus, headlands instead of bays are formed. They are defined by huge chunks of rock that drop in a sudden manner into the sea. Although they resemble rock, they are not equivalent to actual rock. Cliffs can be viewed as headlands.

Examples of bays include:–

  • Bay of Bengal
  • Hudson Bay
  • New York Bay

New York BayHeadlands is a good example. Headlands include:

  • Durlston Head
  • Doran Beach

Depositional coasts and landforms

Coasts located near the edge that trails lithospheric plates are more likely to be characterized by extensive coastal plains and low relief. It is believed that the Atlantic, as well as the Gulf coastlines in the United States, are representative. These coasts could have numerous lagoons and estuaries with barrier islands or river deltas. They are distinguished by the collection of a broad range of sediment types as well as diverse coastal ecosystems. The majority of sediments are composed of sand and mud; however, there are gravel deposits present, particularly as shell materials.

Depositional coastlines could be subject to erosion at specific periods and locations due to factors such as storms, the loss of the supply of sediment, and rising sea levels. This latter issue is a continuous issue because of the average annual temperature of the earth increases and the melting of the ice caps. However, the general long-range, long-range pattern on these coastlines is one deposit of sediments.

Beaches and dunes along the coast

There are a variety of specific landscapes that represent coastal areas that belong to each of the three categories mentioned in the previous paragraphs. Most prominent among them are dunes and beaches. They are the most prominent landforms of the barrier islands, strand-plain coastlines as well as many deltas, including those that are dominated by waves.


The beach’s consideration must include the seaward-facing nearshore environment since they are closely related. The nearshore ecosystem extends from the edge of longshore bars, which typically are present, until that low tide line. In places where there are no longshore bars, they can be considered as being part of that of the surfing zone. Beaches extend from the low tide line and are characterized by a distinct change in elevation and/or the material that lies to the west of the active and unvegetated area of accumulation. It can be composed of gravel, sand, or even mud. Sand is the most commonly used beach material.

Coastal dunes

Just to the landward side of the beach are often seen significant, linear accumulations of sand, referred to as dunes. (For the coverage of dunes in semiarid and desert regions, look up dunes.) They form when the winds carry sediment from the beach towards land and deposit it at any point where obstacles hinder further transport. 

The availability of sediment is the main limitation to the development of dunes and is the principal reason that some dunes along the coast, like those found located on the west Florida peninsulas, appear very small, while other areas, such as those along the Texas coastal areas, and Florida panhandle are characterized by massive dunes.

The dunes’ sediment is usually acceptable to medium sand, which is relatively well-sorted. Shell debris, or other debris, is rare unless it’s of the same mass or size as the sand from the dunes. There are many kinds of plants that are able found on the surface of the dune and help to stabilize it. The vines and grasses appear on the backshore of beaches too. 

  • Dunes without vegetation are typically active and show various indications of sand movement. The most common are the everywhere ripples that are found on the surface of the dune. Massive lobes of sand, or even a whole dune, can shift as winds blow across the dunes. This can result in an enlargement of the dunes into enormous sweeping patterns of wedge-shaped sand.
