Rivers and watersheds of Spain

Spain's territory is split into nine large inter-regional river basins, each managed by its own Hydrographic Confederation: Ebro, Duero, Tajo, Guadiana, Guadalquivir, Cantabrian, Mino-Sil, Jucar, and Segura. We tour the geography of each basin, the rivers that define it, and how a country with both Atlantic and Mediterranean rivers organizes water management at the scale of whole watersheds.
