| |
| − | | |
| − | The basis of this article is especially written for the Coastal Wiki by the main author referred to at the bottom of this page.
| |
| − | This article gives insight in the application and the implications of artificial nourishments.
| |
| − | For an additional view on methods, functional characteristics and applicability of artificial nourishments, you are referred to the article [[shore nourishment]].
| |
| − | | |
| − | ===Introduction===
| |
| − | | |
| − | Artificial nourishments are examples of projects where the coastal system is fed with sediments (sand) from a source (borrow area) at a certain distance from the project area.
| |
| − | Other examples of projects where the coastal system is fed, are large scale land reclamation projects and the construction of an artificial island in open sea. In these cases often huge volumes of sand are required; up to several hundreds of millions m3 per project.
| |
| − | | |
| − | In this article on artificial nourishments applications with moderate volumes per project are discussed (order of magnitude up to 10 million m3 per project).
| |
| − | | |
| − | But why should one apply artificial beach nourishments? Artificial nourishments can be applied in various cases; e.g.:
| |
| − | #to broaden the beach (recreation purposes);
| |
| − | #to create entirely new beaches (recreation purposes);
| |
| − | #to enhance the safety of the mainland or to enhance the safety of properties built rather close to the edge of the dunes;
| |
| − | #to compensate losses because of [[structural erosion]]. | |
| − | | |
| − | The first three cases are to be considered as applications to improve an existing undesirable situation. With a mainly single action a ‘better’ situation is achieved. In principle a single action indeed, although often some relatively small maintenance nourishments are necessary in order to keep the situation as required according to the design conditions.
| |
| − | | |
| − | In the fourth case artificial nourishments are applied as a tool in coastal protection projects. Because of [[structural erosion]] sediments are more or less continuously lost out of a stretch of coast; (frequent) artificial nourishments are required to compensate on average the occurring losses.
| |
| − | | |
| − | So depending on the actual aim of the nourishment project, the nourishment can be carried out as a mainly '''single''' action or the nourishment has to be repeated on a '''regular''' basis.
| |
| − | | |
| − | To carry out an artificial nourishment project, various methods can be applied; see e.g. xxxx)
