Sep 27, 2021 · Results of this study document how beaches and foredunes at Cape Lookout National Seashore, North Carolina, have changed using airborne lidar and offer three metrics that represent the processes that either build or destroy sand dunes.

Jun 4, 2020 · Dune erosion occurs when storm surge elevates waves higher on the beach, allowing them to attack and erode the coastal dune. As sand is removed from the dune, the front face becomes very steep, or scarped. The overall volume and elevation of the dune is reduced due to the erosion process (Figure 3).

Sand loss from a dune under wave attack, mainly by notching, avalanching and slumping processes. This article deals with dune erosion by storms and provides some simple rules from which retreat of the dune front can be estimated. The focus is on the so-called 'collision regime', where waves hit the dune without exceeding the dune crest. Fig. 1.

Sand dune stabilization is a coastal management practice designed to prevent erosion of sand dunes. Sand dunes are common features of shoreline and desert environments. Dunes provide habitat for highly specialized plants and animals, including rare and endangered species .

Sand dune areas, and steeply sloped and sparsely vegetated inland sandy areas often present challenges to site stabilization and the prevention of erosion. Coastal sand dunes are dynamic systems where sand movement is a natural process. …

Jul 3, 2014 · we optimize plants in dune ecosystem restoration to maximize the resilience of coastal dunes against erosion from wave and storm surge attack? This paper will review the current state

Mar 1, 2025 · Aeolian-driven sand dune erosion is an escalating environmental and socioeconomic challenge in arid and semi-arid deserts, particularly in the Thar Desert, which faces intensified dune migration due to climate change and increased anthropogenic activities.

Jul 1, 2023 · Sand dunes are formed by the process of wind erosion and deposition. Wind erosion occurs when wind picks up sand particles and carries them away from their original location. This process can remove sand from rocks and other surfaces, …

May 2, 2023 · As the first natural line of defence against flooding and coastal erosion, sand dunes have an important role to play in sheltering these areas. But today’s sand dunes don’t provide as much protection as they once did.

At Great Sand Dunes National Park, erosion is responsible for recycling escaping sediments back into the main dune field and bringing in new sediments from the surrounding mountains. Alluvium, or sediments deposited by bodies of water, is the source most of the sand in the dunes.
