heal.abstract	The rock falling phenomena constitutes one of the most important categories in slope failure. These falls concern primarily rocky formations and account for the abruption of parts of the rock mass. For the consequences of the phenomena to be avoided it is deemed necessary its systematic research and the construction of effective measures of containment, which is achieved with the use of the suitable software. In this research it was conducted an analysis for the abruption-fall of rocky parts in Chora Sfakion, municipality of Chania, and the causes that creates them. For the precise prediction of the rock falling a simulation in a computing environment has taken place. For the accuracy of the analysis certain coefficients has been used, which are depended from factors such as the characteristics of the fragment (weight, size, shape, strength, etc.), the dynamics (angular velocity of impact, impact angle, fragment orientation), or the plane’s rocky surface characteristics (gradient, roughness, strength etc.). Furthermore, it was conducted a hazard evaluation for the region under study. The region, according to analysis it is risky for falls, therefore need to be designed and placed protective measures. The risk in the slope is from low to high. In the sections that the risk is high, mainly due to the large volume of rock, that lie on the surface, and the height of the slope. To reduce the risk should take protective measures. More effective protection measure is, depending on the research area, rock traps for high risk parts and metal mesh for medium risk parts.	en
