The average overtopping discharge is an important parameter for the design and reinforcement of dikes. Rock armour on the waterside slopes and berms of dikes is widely used to reduce the wave overtopping discharge by introducing slope roughness and dissipation of energy in the permeable armour layer. However. methods for estimating the influence of a rock berm and roughness of rock ar... https://macorners.shop/product-category/led-light-acrylic-plaque-with-infinity-necklace/
