+<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.</p>

 <h2>INPUT</h2>

+<p><b>Digital Elevation Model</b> = name 
     <ul>Name of elevation raster map</ul>
-<p><b>Starting points</b> = name </p>
+<p><b>Starting points</b> = name 
     <ul>Name of vector map containing rockfall source area. It can be one point or more.</ul>
-<p><b>Shadow angle</b> = integer </p>
+<p><b>Shadow angle</b> = integer 
     <ul>Angle of inclination that defines the propagation zone. It's calculated from an horizontal plane starting from source point: highest values determine a lowest propagation.</ul>
-<p><b>Reduction value</b> = double </p>
+<p><b>Reduction value</b> = double 
     <ul>Reduction moltiplicator for velocity. Default value is 0.9</ul>
-<p><b>Number of boulders</b> = integer </p>
+<p><b>Number of boulders</b> = integer 
     <ul>For each starting point can be generated other random points used in the computations. By default points are located in a radius from the starting point equal to: (cell size * number of boulders)/2. Insert 1 for use only the original starting point or points. Note that a high number of boulders can make excessively long the calculation times.</ul>
-<p><b>Rock mass</b> = double </p>
+<p><b>Rock mass</b> = double 
     <ul>Value of rock mass (Kg) </ul>

-<p><b>Buffer distance</b> = integer </p>
+<p><b>Buffer distance</b> = integer 
     <ul>This value define the radius for randomly generatin boulders starting from starting point. It's in the option dialog window.</ul>
