How does sediment size affect beach profile
WebMay 11, 2014 · Last updated on May 11, 2014 Beach Profiles Shingle beaches typically have a steep gradient (over 10˚) because the waves easily flow through the coarse, porous surface of the beach, decreasing the effect of backwash erosion and increasing the formation of sediment into a steep sloping back. WebSediments that are too coarse grained may not move and shift as intended and could increase erosion and other problems. Sediments with a larger grain size may negatively affect the quality of the beach for recreation …
