RT Conference Proceedings T1 Monitoring and preliminary analysis of the natural responses recorded in a poorly accessible streambed spring located at a fluviokarstic gorge in Southern Spain A1 Martín-Rodríguez, José Francisco A1 Mudarra-Martínez, Matías A1 Andreo-Navarro, Bartolomé A1 De la Torre Martínez, Beatriz A1 Gil-Márquez, José Manuel A1 Martín-Arias, Javier A1 Nieto-López, José Manuel A1 Prieto Mera, Jorge Jesús A1 Rodríguez-Ruiz, María Dolores K1 Karst AB The analysis of natural responses (hydrodynamic, hydrothermal and hydrochemical) of karst springs is a well-established approach to provide insights into the hydrogeological functioning of the aquifers that they drain. However, a suitable monitoring program of these responses are often difficult to launch in poorly accessible streambed springs, due to the mixing between surface water and groundwater, in addition to topographic impediments. This work describes the installation procedure of the measurement equipment and the preliminary hydrogeological dataset collected at the Charco del Moro spring (Southern Spain) during one year. This outlet emerges 5 m below water surface, at the bottom of a partially flooded 20 - 200 m deep and 2 km long gorge, eroded by the Guadiaro River streamflow. It is considered the largest discharge point in the region, draining groundwater from northern nearby carbonate outcrops, although its catchment area is not established yet. Continuous (hourly) monitoring of electrical conductivity, water temperature, turbidity and water level (discharge) reflects a high degree of heterogeneity in the duality of groundwater flow and storage dynamics, which is typical of karst conduit flow systems YR 2018 FD 2018-07-06 LK https://hdl.handle.net/10630/16154 UL https://hdl.handle.net/10630/16154 LA eng NO Universidad de Málaga.
