A seawall (or sea wall) is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation and leisure activities from the action of tides and waves. As a seawall is a static feature it will conflict with the dynamic nature of the coast and impede the exchange of sediment between land and sea.
The coast is generally a high-energy, dynamic environment with spatial variations occurring over a wide range of temporal scales. The shoreline is part of the coastal interface which is exposed to a wide range of erosional processes arising from fluvial, aeolian and terrestrial sources, meaning that a combination of denudational processes will work against a seawall. Given the natural forces to which seawalls are constantly subjected, maintenance (and eventually replacement) is an ongoing requirement if they are to provide an effective long-term solution.
The many types in use today reflect both the varying physical forces they are designed to withstand, and location specific aspects, such as: local climate, coastal position, wave regime, and value of landform. Seawalls are classified as a hard engineering shore based structure used to provide protection and to lessen coastal erosion. However, a range of environmental problems and issues may arise from the construction of a seawall, including disrupting sediment movement and transport patterns, which are discussed in more detail below. Combined with a high construction cost, this has led to an increasing use of other soft engineering coastal management options such as beach replenishment.
Seawalls may be constructed from a variety of materials, most commonly: reinforced concrete, boulders, steel, or gabions. Additional seawall construction materials may include: vinyl, wood, aluminium, fibreglass composite, and with large biodegrable sandbags made of jute and coir. In the UK, sea wall also refers to an earthen bank used to create a polder, or a dike construction.
The seawall in Vancouver, British Columbia, Canada is a stone wall that was constructed around the perimeter of Stanley Park to prevent the erosion of the park's foreshore. Colloquially, the term also denotes the pedestrian, bicycle, and rollerblading pathway on the seawall, one which has been extended far outside the boundaries of Stanley Park and which has become one of the most-used features of the park by both locals and tourists. James "Jimmy" Cunningham, a master mason, dedicated his life to the construction of the seawall from 1931 until his retirement. Even after he retired, Cunningham continued to return to monitor the wall's progress, until his death at 85. While the whole path is not build upon the seawall; the total distance from CRAB park, around Stanley Park and False Creek to Spanish Banks is about 30km.
Despite perennial conflicts between pedestrians, cyclists, and inline skaters, park users consider the seawall to be the most important feature of Stanley Park and it is the most used facility within the park.
