Introduction to Coastal Structures

9th December 2019, London

This course introduces the design and analysis of coastal structures, especially breakwaters, seawalls, jetties / piers. It discusses the hydraulic effects of tides, surges and waves with tutorial examples on wave generation, encounter probabilities, and depth-limited wave heights.


As grounding to separate courses covering the detail of design / analysis methods for breakwaters, seawall, or jetties, this introductory course devotes most effort to ensuring that attendees have a robust understanding of coastal hydraulics, particularly the derivation of wave action and its effects on coastal structures and their surroundings. Hands-on tutorial examples address the calculation of depth-limited wave action, essential for analysis of most nearshore coastal structures, and the practical use of results of Joint Probability Analysis.


Breakwaters and seawalls all interact with local coastal processes, so the course identifies typical coastal landforms and describes features of importance to the construction and performance of coastal structures. Then, having given a wide range of coastal structures, the course will conclude with tutorials on wave overtopping (simplified), rubble mound armouring, and wave forces on vertical walls or elevated decks.



Part 1 will explore the following areas: Introduction to surges, tides, waves; predicting wave conditions; wave shoaling / refraction; depth-limited breaking; using Joint Probability Analysis.


Part 2 will explore the following areas: Coastal processes; landforms and sediment movement; beaches; dunes; beach control structures and nearshore breakwaters.


Part 3 will explore the following areas: Armoured structures; holding the line or retreat; rubble mound breakwaters; rock armouring and armour sizing formulae; concrete armour units.


Part 4 will explore the following areas: Wave overtopping; predicting overtopping discharges; allowable discharges.


Part 5 will explore the following areas: Vertical walls; example structures; walls and caissons; pulsating vs impulsive loadings; wave load prediction methods; vertical wall overtopping;


Part 6 will explore the following areas: Jetties and piers; wave loadings.


About the Lecturer

Nigel William Henry ALLSOP founded William Allsop Consulting in 2017. To January 2018 he worked at HR Wallingford for 48 years where he was Technical Director for Maritime Structures responsible for consultancy and research studies, technology development covering design, analysis, testing, and optimisation of breakwaters, sea walls, revetments, jetties / piers and wide range of reservoir, shoreline, estuarial and coastal structures.


William has 45+ years' experience of analysis and testing of breakwaters (rubble mound, vertical and composite), sea walls, revetments, piers / jetties and coastal / shoreline structures, engineering works or renewable energy systems in tidal estuaries, and rivers, in sand and cohesive sediment transport, of river structures, outfalls and oil booms, and performance and certification of temporary flood protection devices. He has supervised testing in large facilities in UK, France, Germany, Italy, Spain, Turkey. He devised the UK’s first laboratory Tsunami Simulators which have tested tsunamis at 1:50 scale.


He has been responsible for research to advance design methods for breakwaters and coastal structures in collaboration with other UK and European researchers. He has cooperated on research projects in UK, Europe and USA, particularly in VOWS, Big-VOWS, PROVERBS, CLASH and Floodsite. He has served on ICE Maritime Board, PIANC working groups, and has contributed to PIANC, BSI, ISO and ICE working groups, the Rock Manual, Revetment and Exposed Jetties Manuals, and revisions to the BS6349. As Visiting Professor at Southampton (previously at Sheffield, Belfast, and UTM), Honorary Professor at University College London and guest lecturer at ESITC Caen, William has developed a series of training course based on industry needs.
