Full title and description

ISO 21650:2007 — Actions from waves and currents on coastal structures. This International Standard specifies principles and recommended procedures for determining hydrodynamic actions (waves and currents) acting on coastal and estuarine structures such as breakwaters, seawalls, coastal dykes and cylindrical structures (jetties, dolphins, lighthouses, pipelines, etc.).

Abstract

ISO 21650:2007 provides methods to evaluate wave and current loads for design at different levels (concept, feasibility and detailed design), with an emphasis on detailed design. It covers rubble‑mound, vertical and composite breakwaters, wave screens, floating breakwaters, coastal dykes, seawalls and cylindrical structures, and it identifies excluded topics (for example, harbour layout, sediment‑transport layout, detailed scour/beach stability design and the dynamic response of flexible structures except for vortex‑induced vibration).

Scope

ISO 21650:2007 establishes principles and recommended procedures for determining wave- and current-induced actions on coastal and estuarine structures. It is intended for use in the detailed design of permanent coastal works and deals with the hydrodynamic loads and parameters needed for structural design. The standard explicitly excludes topics such as harbour layout, sediment‑transport and beach‑stability design, detailed scour design, and the general dynamic response of flexible/dynamic structures except where vortex‑induced vibration is relevant.

Key topics and requirements

• Definitions and terminology for waves, currents and water levels relevant to coastal design.
• Characterisation of wave climate and current conditions for design (statistical parameters and representative sea states).
• Procedures to estimate wave and current actions on different types of coastal structures (rubble mound, vertical/composite, floating breakwaters, seawalls, dykes, cylindrical structures).
• Recommended design levels (concept to detailed design) and how to select representative load cases.
• Guidance on reduction factors, hydrodynamic coefficients, and treatment of combined actions (wave + current + water level).
• Limitations and exclusions (harbour layout, sediment management, detailed scour/beach stability, flexible dynamic response except vortex‑induced vibration).

Cited material and topic coverage are summarised from the ISO standard text and official synopsis.

Typical use and users

Civil, coastal and marine engineers; structural designers of coastal works; port and harbour authorities; consultants and contractors involved in coastal defences and breakwater design; academic researchers and students in coastal engineering; standards committees and national bodies preparing complementary guidance or national annexes.

Related standards

ISO 21650 sits within ISO/TC 98/SC 3’s body of work on marine and coastal structures. Users commonly consult it alongside other national and international standards and best‑practice documents covering wave measurement, harbour engineering, geotechnical design for marine structures, overtopping and wave run‑up guidance, and environmental and hydrodynamic site characterisation produced by ISO, CEN/EN, national standards bodies and specialist industry organisations.

FAQ

Q: What is this standard?

A: ISO 21650:2007 is an International Standard that specifies principles and procedures for determining actions from waves and currents on coastal and estuarine structures, intended primarily for detailed design.

Q: What does it cover?

A: It covers the characterisation of wave and current conditions, calculation of hydrodynamic actions on various coastal structure types (rubble‑mound, vertical/composite, floating breakwaters, seawalls, coastal dykes, cylindrical structures), recommended design levels and important exclusions (for example harbour layout and detailed sediment‑transport design).

Q: Who typically uses it?

A: Coastal and marine engineers, structural designers, port authorities, consultants, contractors and researchers involved in the design, assessment and maintenance of coastal defence and marine structures.

Q: Is it current or superseded?

A: ISO 21650:2007 is published and has been the confirmed International Standard following systematic reviews; users should verify the current status with the ISO catalogue or their national standards body to ensure no later revision or replacement exists.

Q: Is it part of a series?

A: It is part of the body of work produced under ISO/TC 98 (particularly SC 3 on marine structures) and complements other ISO and national standards and technical reports addressing coastal, offshore and harbour engineering topics.
