Zusammenfassung:In this paper is analyzed the hydrological response of Cinca and Esca headwaters, and Ésera basin to a intense precipitation episode, produced in central Pyrenees from 17th to 19th june 2013. 122 meteorological stations are used to study rainfall behavior in different temporal scales, and 7 gauges to view temporality and intensity on flow responses. Rainfall discharge was not unusual in historical series, but it joined to a snowmelt, which produced an increase on flow at highest headwaters. The consequences of floods have reactivated fluvial geomorphic processes, reoccupying former floodplain, although the intense territorial occupation of the last 50 years in the Valley of Benasque has produced that exposure to risk is much higher as a result of poorly controlled urban growth.
