Detailed course on the main design methods for rubble mound breakwaters, with commentary on the practical implications.
Seawalls or breakwaters have been built on the coastline since the earliest stages in man's development of the coastal zone. The primary purposes of such
structures are to defend land against erosion or flooding or to protect areas of water for navigation, anchorages or sheltered moorings. Many coastal,
shoreline, or harbour structures are required to serve multiple purposes, some of which may change in time. One such type of coastal structure consists
of a rubble mound or slope formed of quarried rock protected by layers of rock and/or concrete armour units.
This course combines detailed teaching on the main design methods for rubble mound breakwaters, with commentary on the practical implications. Strong emphasis
is placed on understanding the concepts behind the main design methods, being familiar with representative parameters and with key outputs, so hands-on
tutorials are included throughout the course.
An overview of the types of rubble structures used near and on coastlines.
The likely magnitude and effect of waves, tides, and surges on coastal structures, and potential effects of climate change on their performance and
Understanding and applying analysis methods for wave overtopping / transmission, and therefore the determination of breakwater crest height.
Applying design methods for armour size of rock and concrete units, calculating the effects of wave conditions, structure permeability, and storm duration.
Understanding rock durability, selection, handling and placement.
Applying design methods for concrete armour units and understanding issues for fabrication and placement.
Who should attend?
Coastal and harbour engineers, and owners of rubble seawalls, breakwaters or related coastal structures.
At the end of the course participants will:
be familiar with key coastal processes affecting the design of coastal structures;
be aware of the types and breadth of coastal structures in use;
have had hands-on experience of key input parameters, application of prediction tools, and understand levels of confidence for their calculations;
understand the significance of different sources of guidance, including recent research results;
be able to devise alternative solutions with confidence.
