| Summary: | The Careo ditches, hydraulic elements of an ancestral water management system, play an essential role in the hydrological functioning of watersheds in Sierra Nevada (South of Spain). This study seeks to characterize the hydrochemical and stable isotope compositions of surface water and groundwater in the high mountain watershed of the Alhorí river. For this purpose, 46 samples from springs and surface streams were collected in June 2020 and their content in major ions, hydrogen and oxygen isotopes was analysed. The results show that altitude is clearly influencing the characteristics of the sampled waters. Furthermore, artificial groundwater recharge with careo ditches favours evapoconcentration. Overall, this research proves the existence of short-distance flows in the groundwater of the Alhorí river basin |
