DBTR2008 — Natural Watercourse — (FIU_GLI)

The route is constructed by means of the orderly aggregation of ‘water elements’ (in particular ‘Water rods’ as part of the drainage network of the corresponding hydrographic basin) which have continuity characteristics, except in cases where the underground path is not reconstructable, and towards homogeneous.Portions of the watercourse can be defined as secondary if they correspond to secondary branches of the same watercourse both at the beginning and at the end of the watercourse with each natural watercourse may be associated with a point representing its origin; all the reference points can be positioned on the rod by the distance from that point (this is the case of the sections that are identified precisely by this information.The entities of Natural Water Course represent an aggregation of entities of “Element of watercourse”.
