Description
The hydrographic breakdown is the four hierarchical partitions of the French territory carried out according to decreasing hydrographic areas:
— hydrographic region (1st order),
— hydrographic sector (2nd order),
— hydrographic sub-sector (3nd order),
— hydrographic area (4nd order).
A hydrographic region is divided into a maximum of 10 sectors and one sector is divided into a maximum of 10 sub-sectors.
The definition of the sectors and their limits is the responsibility of the Water Agencies.
