Breakwater Ocean & Coastal Engineering Faculty Content 1. Introduction 2. Types of breakwaters 3. Caisson breakwater (vertical wall BW) 4. Revetment breakwater (rubble-mound BW) 5. Summaries Introduction • Definitions: Breakwater is a structure that protects the area in its lee from wave attack. • Purpose of breakwaters: + To provide shelter from the waves + Through this shelter, to manipulate the littoral transport conditions and thereby to trap some sand Types of breakwaters - Detached breakwater (Breakwaters be completely isolated from the shore ) + Headland breakwaters + Nearshore Breakwaters - Attached breakwater (Breakwaters can be connected to the shoreline) - Low crested structure - High crested structure - Rubble mound structure - Composite structure - Emerged breakwaters - Submerged breakwaters - Floating breakwater - Using mass (Caissons) - Using a revetment slope (e.g. with rock or concrete armour units ) Types of breakwaters Breakwater in Presque Isle, Pennsylvania (1994) Shoreline Breakwater, Elmer, UK [...]...Caisson breakwater • • • • • Definition Applicable conditions (cases???)
