This function calculates an estimated average slope of a catchment by calculating the slope between two points on the defined watercourse.

The first point is taken at 10% of the watercourse length. The second point is taken at 85% of the watercourse length. DTM spot heights are taken at each of these coordinates and used to determine a slope.

A DTM will need to be loaded.
