EFFECT OF GRAVEL PARTICLE SIZE ON THE RESHAPING OF DYNAMIC REVETMENTS

Gravel beaches are prevalent natural features on many coastlines and play a vital role in shore protection, often inspiring protection structures (Bayle et al., 2020) nature-based solutions. Dynamic revetments constructed features, designed to mimic gravel beaches, dissipating wave energy preventing or limiting erosion. Compared sand dissipate incident dampen backwash intensity by percolating through the relatively large pore volume space (Komar, 2007). During storm events, particles move up beach, accreting at crest. This predominately onshore-directed transport of material differs from storm-driven morphodynamic behaviour sandy which tend exhibit higher rates offshore-directed Ahrens’ Theorem continues be used as design estimator for dynamic 2020). primary objective this study is investigate how with different D50 reshape under various conditions.
