Gebiet bzw. Fläche, aus der ein Gewässersystem seinen Abfluss bezieht.
Land area that drains water to a particular stream, river or lake that can be identified by tracing a line along the highest elevations between two areas on a map, often a ridge, and may encompass a number of smaller watersheds (micro-watersheds) that ultimately combine at a common point.
Territoire géographique où toutes les gouttes de pluie tombant au sol s'écoulent et se rejoignent en un même endroit.
Zona che raccoglie le acque piovane e che corrisponde in idrografia all'area topografica (solitamente identificabile in una valle o una pianura), delimitata da uno spartiacque topografico (o orografico o superficiale), di raccolta delle acque che scorrono sulla superficie del suolo confluenti verso un determinato corpo idrico recettore (fiume, lago o mare interno) che dà il nome al bacino stesso.
