		<element name="DESCRIPTION" text="This algorithm calculates the difference between the elevation of each cell and the elevation that would correspond to the same cell within the channel network. For this, an elevation layer is calculated using just the elevation at channel cells and interpolating the elevation of the remaining cells. The difference between this layer and the DEM is then computed." description="Description" type="0">
