Coastline Erosion 5

Tied island

Tied Islands and Tombolos. Many times islands situated away from the coast are connected by bars. Such an island connected with the coast by a bar is called tied Island and the bar connecting it to the coast is called tombolo. There are numerous examples of tied islands and tombolos near the New England coast.

At some places two tombolos develop towards a tied island. The area between the two Tombolos coalesces into one forming a large land area. Such a structure is found at Gibraltar.

Barrier Islands. At many places there are islands near the coast. They are many km. long but are not connected with the main land. Many sand dunes are formed on these. islands with the sand received from the coast. These are known as Barrier Island. Atlanta City is situated on such a barrier Island. Beach and Jones Beach are examples of barrier islands.

Tidal Inlets. The opening between the barrier islands and the coast is called an inlet. Tides keep them open by removing the sand, which tries to close the inlet. Such openings are called Tidal Inlets.

Lagoons. At many places, bars and barriers enclose the coast and form small lakes such lakes are known as lagoons. There are many lagoons found at the eastern coast of India. Lake Chilka is a well-known lagoon on this coast.

Progradation. Sometimes the pebbles, shingles and other sediment are accumulated to such an extent that these cannot be thrown by sea action. Hence a thin layer of sand, pebbles, cobbles, etc., is deposited over the wave-cut platform. When the deposits of wave-built platform becomes one with this sediment the process is called progradation.
