Isotope hydrological study of mean transit times and related hydrogeological conditions in Pyrenean experimental basins (Vallcebre, Catalonia)


, : Isotope hydrological study of mean transit times and related hydrogeological conditions in Pyrenean experimental basins (Vallcebre, Catalonia). Integrated methods in catchment hydrology tracer, remote sensing and new hydrometric techniques Proceedings of an International Symposium held during IUGG 99, the XXII General Assembley of the International Union of Geodesy and Geophysics, at Birmingham, UK, 18-30 July 1999: 101-109

Measurements of tritium and oxygen-18 concentrations in water samples from streams at low discharge, wells, and permanent springs are used to provide insight into hydrogeological conditions, storage properties, runoff formation, and flow partitioning of Pyrenean experimental basins 100 km north of Barcelona, Spain. Transit times as derived from tritium range between 8-11.5 years for wells, 8.5-13.0 years for streams, to 10.5-13.5 years for springs.
