Breakwater design calculation

Hudson's equation, also known as Hudson formula, is an equation used by coastal engineers to calculate the minimum size of riprap (armourstone) required to provide satisfactory stability characteristics for rubble structures such as breakwaters under attack from storm wave conditions. The … See more The equation itself is: $${\displaystyle W={\frac {\gamma _{r}H^{3}}{K_{D}\Delta ^{3}\cot \theta }}}$$ where: • W is the design weight of the riprap armor (Newton) See more This equation was rewritten as follows in the nineties: where: See more • Breakwater (structure) • Coastal erosion • Coastal management • Armourstone See more WebJan 11, 2024 · PDF On Jan 11, 2024, Chidiebere Charles Agoha published Geotechnical Aspects of Breakwater Design and Construction: A Review Find, read and cite all the research you need on ResearchGate
