Abstract
Profiles of a river area analyzed by determining a ruler length characterizing the size of topological features of the river. The perimeter of a transect of the river is then determined by integrating the Pythagorean theorem using selected points on the transect. Main voids occurring in the calculation are measured by dividing the main void into triangular areas and accumulating the triangular areas across the main void.
