+<h2>NAME</h2>
+<p><b>r.droka</b>- <b>D</b>raft <b>Ro</b>c<b>k</b>fall <b>A</b>nalysis - An empirical method that identifies the maximum area of invasion of a rockfall.
<h2>DESCRIPTION</h2>
-<p>The intersection between the topographic profile and the line starting from the point of detachment with a certain angle to the horizontal line defines the point of maximum propagation (Evans and Hungr, 1993; Jaboyedoff and Labiouse, 2003). The angle of inclination (φp) and the line of propagation are defined as zenith angle and shadow zone. This script defines rockfall zones from a digital elevation model (DEM) and vector layer containing starting point or points.
