Sub-basins of river sections, generated from cell 25 x 25 MDT (CEDEX).
The sub-basins obtained have been classified according to the Pfafstetter methodology modified from that used in the classification of stretches of rivers of Spain (hydrographic classification).
The geographical information is polygonal from sub-basins to stretches of rivers, endorreic basins (basins that do not pour into the sea), interbasins (coastal basins between river mouths) and related data.
The methodology applied to obtain this information and its application for the hydrographic classification of rivers in Spain according to the Pfafstetter method has been developed by CEDEX. The detailed information is contained in Monograph M-133 “Hydrographic Classification of the Rivers of Spain” edited by the Center for Publications General Technical Secretary. Ministry of Public Works.
The sub-basins are consistent with the geographical information of “Rios classified from Spain according to the modified Otto Pfafstetter method” (one sub-basin per section), with the map of drainage directions (MDD) and the surface area accumulated in each cell of 25x25 meters (MAF).
