The hydrological significance of mountains: a regional case study, the Ebro River basin, northeast Iberian Peninsula

This study evaluated the hydrological significance of mountain regions, comparing them with the lowlands of the Ebro River basin (northeast Iberian Peninsula). It was based on records obtained from measuring stations. An altitude of 1000 m above mean sea level was adopted as the criterion for distin...

It was based on records obtained from measuring stations. An altitude of 1000 m above mean sea level was adopted as the criterion for distinguishing between lowland and mountain areas. We analysed 12 sub-basins whose rivers flow directly into the River Ebro, and which covered 66% of the total surface area, 91% of the mountain area and accounted for 77% of total annual runoff. For the River Ebro basin, we found that the mean precipitation depth, the runoff volume per unit of surface area, and the runoff coefficient were all greater in the mountains than in the adjacent lowlands, with respective differences of 70%, 180% and 60%. These results and the particular fragility of the Mediterranean mountain ecosystems confirm the mountain regions of the Ebro basin as strategic zones for hydrological and territorial planning.Dans cette étude nous avons évalué l'importance hydrique des régions de montagne par rapport aux plaines du bassin du fleuve Èbre (nordest Péninsule Ibérique), à partir des registres fournis par les stations de jaugeage. Comme critère de distinction entre la plaine et la montagne, nous avons adopté une altitude sur le niveau moyen de la mer de 1000 m. L'analyse a été faite sur 12 sous-bassins qui se jettent directement dans l'Èbre et qui représentent 66% de la superficie totale, 91% de toute la zone de montagne et 77% de l'écoulement annuel. En moyenne, pour le bassin de l'Èbre, les résultats ont montré que la hauteur de précipitation, l'écoulement par unité de superficie et le coefficient d'écoulement étaient supérieurs de 70%, 180% et 60% respectivement dans les zones de montagne par rapport aux plaines adjacentes. Ces résultats ajoutés à la fragilité particulière aux écosystèmes méditerranéens de montagne, confirment que les régions montagneuses de l'Èbre sont des zones stratégiques pour la planification hydrologique et territoriale.International Association of Hydrological Sciences2019201920102019info:eu-repo/semantics/articleinfo:eu-repo/semantics/acceptedVersionapplication/pdfhttps://doi.org/10.1080/02626660903546126http://hdl.handle.net/10459.1/67723http://hdl.handle.net/10459.1/67723reponame:Recercat.
