Rafosite Reef: oswa brutality nan sifas la Reef, kreye friksyon ak trennen kòm vag deplase sou yon resif ki lakòz vag yo kraze ak enèji a yo dwe gaye. Pi gwo fòmasyon koray yo (> 30 cm) kreye plis friksyon ak trennen pase sab la oswa reef a. ref Pou egzanp, trennen sou yon plat Reef ka 10x pi gran pase yon zòn Sandy, se konsa koray sou krèt la Reef ak atravè plat la Reef enpòtan pou disip enèji vag. ref

Reef rugosity: or the roughness of the reef surface, creates friction and drag as waves move over a reef that cause waves to break and the energy to be dissipated. Larger coral formations (>30 cm) create more friction and drag than sand or reef pavement. ref For instance, drag over a reef flat may be 10x greater than a sandy area, so corals on the reef crest and across the reef flat are important for dissipating wave energy. ref
