Rockfall causes a large number of accidents and fatalities in steep environments. A realistic quantification rockfall risk is thus crucial for an effective prevention damages loss lives. The estimation block volumes different return periods thereby remains major challenge. In this paper, we present straightforward frequency model (RFM: Frequency Model) its application at 8 sites 7 locations the...

An approximation technique is considered for computing transmission and reflection coefficients for propagation of an elastic pulse through a planar slab of finite width. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is s...
