WebConstructive waves (with an elliptical orbit and long wavelength of up to 100m) that occur at a rate of 8 or fewer per minute contribute to a gently-sloping beach as there is a stronger swash than backwash, contributing to sediment deposition through gravity settling, and the formation of lateral berms on the beach. WebThe mean grain size of beach sediments depends on the characteristics of the source and the nature of the sedimentary processes. Mean grain size varies according to …
