“…The method uses the computer efficiency for local interpolation, considering the reverse of the distance, still maintaining the superficial continuity of the global interpolation methods, such as cokriging and spline. The technique is efficient because it allows the use of archives of points with altitude values, contour lines and drainage, which assist in the reduction of errors and provides a hydrologically consistent model (Carmo et al, 2015;Hutchinson, 1989). Thus, data from the grid of points resulting from the DEM itself, contour lines (20 m) and drainage with a corrected direction of flow were considered (IBGE, 1979).…”
