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 dunes are vulnerable to human activities. Therefore, they need as little human interaction as possible for their protection. Human coastal activities has led to the erosion and loss of plant life on sand dunes. [19] Plant life has been established as an important stabilizing factor of sand dunes and the loss of it will cause more erosion.
Coastal dunes expand laterally as a result of lateral growth of coastal plants via seed or rhizome. [40] [41] Models of coastal dunes suggest that their final equilibrium height is related to the distance between the water line and where vegetation can grow. [42] Coastal dunes can be classified by where they develop, or begin to take shape.
Wind is the important factor here, not water. During strong storms high waves and wind can deliver and erode sediment from the backshore. Dunes. Coastal dunes, created by wind, are typical of a barrier island. They are located at the top of the backshore. The dunes will display characteristics of typical aeolian wind-blown dunes. The difference ...
Northern California coastal dune environments are subject to high velocity winds at all times throughout the year. This strong variable causes the morphology of the dune ecosystem to constantly change. Dunes can range in height from a meter to tens of meters tall creating elevation changes and habitat complexities.
Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. [3] On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion.
A recent San Luis Obispo Superior Court ruling clears the way for off-highway vehicle use to continue at the popular state park.
Beach access is an important consideration where substantial numbers of pedestrians or vehicles require access to the beach. Allowing random access across delicate foredunes is seldom considered good practice as it is likely to lead to destruction of flora and consequent erosion of the fore dunes. A well-designed beach access should:
