The catchment area is defined as the water collection area, considered from an outlet: it is bounded by the contour within which all water flows on the surface and underground to this outlet. Its boundaries are the dividing lines of the waters. In addition to the catchment areas defined in the Carthage BD repository on the basis of the reference watersheds, procedures (e.g. control basins defined by drought protocols) or the specific needs of the services (e.g. river basins or watersheds upstream of a water intake) may lead to the creation of specific watersheds.
