- The Hydrographic Basin
The Douro river basin is the national basin that has the highest flow rate at its mouth, in terms of water volume. It has numerous tributaries in the national territory, the most important being, on the right bank, the Sabor, the Tua, the Corgo, the Tâmega and the Sousa, which run almost all of them from northeast to southwest, and on the left bank, the Águeda, the Coa , Távora, Varosa, Paiva and Arda, which run in a direction perpendicular to the banks, that is, approximately from southwest to northeast. All these tributaries are plateau rivers, with large bumps in their bed and strong erosive power, well evidenced by the recessed valleys and deep gorges that almost all of them have.
