(1) This document provides additional provisions to EN 1991-1-8 giving principles and recommendations to determine wave and current actions and action effects on sloping structures, such as rubble mound breakwaters, in the coastal zone, i.e. works connected to, or in close vicinity to the shore.
NOTE 1 As opposed to offshore conditions, waves or currents in the coastal zone are generally affected by the presence of the seabed or shore.
NOTE 2 The coastal zone is typically defined as the area between the shoreline and the deep-water limit.
(2) This document defining the hydrodynamic conditions to be used for design.
(3) EN 1991-1-x addresses specifically actions from currents and waves on the following structure types:
- rubble mound breakwaters: conventional, with berm, low-crested and submerged;
- rubble mound part of composite breakwaters;
- revetments.
(4) Actions addressed in this document do not cover:
- hydraulic resonance in sheltered areas or basins (phenomena also known as harbour resonance);
- translation waves, e.g. tsunamis;
- waves and currents induced by maritime operations, i.e. vessel wake, berthing and mooring;
- hydrodynamic actions induced by earthquakes;
- ice-induced pressures and forces;
- coastal structures where flood risk management is their dominant function
