Beaches Can Survive Sea Level Rises As Long As They Have Space to Move

Below excerpts are from an October 27th article published on Phys.org by the University of Plymouth. The full article is available here.

“There is potential for beaches to migrate landwards as sea level rises and shorelines retreat.

“The key notion behind that is that if beaches have space to move into under the influence of rising sea levels—referred to as accommodation space—they will retain their overall shape and form but in a more landward position.

“The new research says that beaches backed by hard coastal cliffs and engineering structures, such as seawalls, are indeed likely to disappear in the future due to sea-level rise as these beaches are unable to migrate landward…

“However, beaches backed by low-lying coastal plains, shallow lagoons, salt marshes and dunes will migrate landward as a result of rising sea level. In these cases, the shoreline will retreat, but the beaches are still likely to remain, albeit a little raised in elevation and located landward, and will certainly not go ‘extinct’.”
