WebHudson'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. WebProtecting bridge piers with loose rock riprap David C. Froehlich∗ Consulting Engineer, 303 Frenchmans Bluff Drive, Cary, NC 27513, USA (Received 25 September 2012; accepted 19 July 2013) An expression for sizing loose rock riprap placed around bridge piers is derived based on an evaluation of moments that fily brass

Web13.3.3 Riprap aprons Outlet protection can take the form of riprap placement with the stone sizing being done as part of the storm drainage design, and using these guidelines. Riprap outlet protection is usually less expensive and easier to install than concrete aprons or energy dissipators. A riprap channel lining is flexible and adjusts to ...
