Abstract

The presence of numerous boulders on rocky coast is linked to phenomena of detachment and deposit due to the occurrence of sea storms. Currently, several hydrodynamic equations are known in the bibliography to estimate the wave height able to displace them, applying geometric parameters and hydrodynamic coefficients. A new methodological approach intends to consider the minimum energy required for the linear movement of a boulder along a weakly sloping rocky surface as a function of the friction coefficient.Boulders
