| Description |
Maintained by the National Administration "Romanian Waters" (Administrația Națională "Apele Române" — ANAR) and harmonized to the INSPIRE Hydrography schema (Watercourse.gml), this dataset provides the official digital vector representation of Romania's cadastral hydrographic network (Rețeaua Hidrografică Cadastrală a României). Derived from the 1:100,000 Hydrographic Map of Romania in the 1992 Water Cadastre Atlas of Romania (originally produced by Aquaproiect and RAAR with INMH, IGFCOT, IG, and ICAS) and updated with modern refinements, it delineates well-defined, quasi-permanent watercourses meeting the national cadastral threshold (minimum catchment area of 10 km² and minimum length of 5 km). Rivers up to order 6 are classified using an adapted Gravelius coding system organized across Romania's 15 first-order river basins (Tisa, Someș-Crasna, Crișuri, Mureș-Aranca-Ier, Bega-Timiș-Caraș, Nera-Cerna, Jiu, Olt, Vedea, Argeș, Ialomița, Siret, Prut, Danube, and Litoral). |
