Abstract
The presence of numerous boulders on rocky coast is linked to phenomena of detachment and deposit due to the occur-rence of sea storms. Currently, several hydrodynamic equations are known in the bibliography to estimate the wave height able to dis-place 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.File in questo prodotto:
