DBTR2008 — Channel — (CAN_GLI)

It is a river made by man with the insertion of an artifact (channel) in natural or artificial materials for the purpose of supply, irrigation, drainage, diversion, uncovering of the flow rates of floods, production of hydroelectric power, navigation or other. It normally has an average or weak slope. It is modeled by the orderly aggregation of “watercourse elements” that have continuity characteristics, except in cases where the underground path is not rebuildable, and towards homogeneous.The presence of loops and secondary branches is however not foreseen.The direction of travel of the constituent elements must be consistent with that of the current of the channel itself, therefore determined on the basis of the altitude of the soil. For channels that allow a double direction of flow, however, a single direction must be assumed for the whole channel.The routes of the canals must be continuous and be organised in such a way as to connect at the points of derivation or delivery in general with a natural hydrographic network or possibly with the ducts, acquiring also: “the centreline of the channel sections not visible (e.g. drained)” the sections of connection with the natural water courses (virtual centreline) in correspondence to the derivation or delivery situations
