Another well-known tombolo is the Aupouri Peninsula in New Zealand.
The island is then referred to as a linked island once it has been joined.Due to sand accretion in the lee of the island, where wave energy and longshore drift are reduced and hence sand deposition occurs, the shoreline creeps toward the island (or detached breakwater).

Passing ThroughIt takes ships about 8-10 hours to cross the Isthmus of Panama through the Panama Canal. They are mostly formed by the depositional process of longshore drift, which is when material is transported along the coast at a right angle. Longshore drift is the cause of a spit forming at the mouth of a river. In the case of longshore drift due to an oblique wave direction, like at Chesil Beach or Spurn Head, the flow of material is along the coast in a movement which is not determined by wave diffraction around the now tied island, such as the Isle of Portland, which it has reached. Longshore drift is the progressive dragging of materials along the beach as a result of waves breaking at an angle.
