![]() ![]() However, the protection against flooding offered by the seawall can benefit settlements and economic activities. Tourists and tourism industry as well as other recreational users will therefore be affected. A seawall as well as a jetty can negatively affect the landscape and the use of the beach, or can be used to artificially widen the beach to create recreational space. Several categories of stakeholders can be affected by strengthening seawalls or jetties. Similarly, the Floods Directive, the Water Framework Directives and the Maritime Spatial Planning Directive establish public participation processes that may be relevant for these projects. If a project could create a significant impact on a Natura 2000 sites, the ‘appropriate assessment’ of the infrastructure project may include a public participation process, though this is not mandatory. If an EIA is undertaken, the EU Directive provides for the right to access information and to participate in the environmental decision-making procedures to the public concerned by the project. Structural and physical: Engineering and built environment options Jetties are not usually adaptation measures per se, but may be connected with seawalls or other hard coastal defence structures. Jetties can be constructed with concrete, stone, timber or steel. ![]() Jetties will affect longshore transport of sediment and ecological processes (see success and limiting factors). Parallel jetties are frequently built to delimit a navigation channel. It usually does not have a shore protective function (which instead breakwaters do). Seawalls are often found in the case of narrow or steep beaches, where a typical breakwater is either too large or not economical.Ī jetty platform on wooden or concrete piles built into the sea to protect a navigation channel and it allow the berthing of ships. A seawall creates a distinct separation between the beach and the mainland. The crest of the wall often extends into a stone covered part that may be used for a road, promenade or parking area. Seawalls are also used to stabilize eroding cliffs and protect coastal roads and settlements. The height of a seawall will at least cover the difference between the beach level and the mainland, though commonly seawalls are built higher to protect the land against wave overtopping. Seawalls are usually massive structures designed to resist storm surges. At this point, verify that the parameters are correct.A seawall is a structure made of concrete, masonry or sheet piles, built parallel to the shore at the transition between the beach and the mainland or dune, to protect the inland area against wave action and prevent coastal erosion. The GenCade Seawalls dialog will appear allowing the entry of seawall parameters.
