An estimation of the erosion dynamic of the Saint-Eynard cliff near Grenoble in France,&nbsp;is performed using a lidar detection method of rockfall between 2015 and 2017. The detection of the&nbsp;rockfall allows to set an inventory of past events. Based on this inventory, a power law is fitted to model&nbsp;the frequency-magnitude of the fallen blocks. A stability analysis of the fitted power law distribution is&nbsp;performed making the use of a eight years database on the Saint-Eynard cliff from previous studies. Further,&nbsp;the use of the lognormal distribution to model the frequency-magnitude is evaluated and compared to the&nbsp;power law fittings. It appears that both the power law and the lognormal distribution model with the same&nbsp;order of accuracy the frequency-magnitude distribution of the rockfalls. Finally, a preliminary work on a&nbsp;semiquantitative analysis of propagation hazard is performed using the Rockyfor3D and Trajecto3D model.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>C\u00e9cile d\u2019Almeida Supervisors: Prof. Michel Jaboyedoff, MSc.&nbsp;Antoine Guerin Rockfall hazard is a major concern in mountainous area and its characterization is needed to set proper&nbsp;safety dispositions.
