Variaciones temporales y espaciales en el intercambio entre aguas subterráneas y superficialesEl humedal de La Charca de Suárez. Granada, España

Résumé

La Charca de Suárez (LCS) Nature Reserve is a wetland reserve located in the south of Spain, 300 m from the coastline of the Mediterranean Sea. The protected area encloses 4 lagoons that are placed in depressed areas of the old Guadalfeo river mouth, where water table is closed to the surface.The aim of this study is to present a first approach of the hydrodynamic behavior of these system based on preliminary measurements collected at present, with emphasis on understanding the interrelation between lagoons and the Motril-Salobreña aquifer. Blanco-Coronas, et al.(2020) described the monitoring network installed to collect data: wetland water level and groundwater level measurements,surface water inlet and outlet of the wetland system, and exchanged flux between both water bodies (wetland and aquifer). Furthermore, a meteorological station and anevaporation tank obtained thehydrometerological data and water samples were collected for hydrochemical analysis.Results show that one of the wetlands has a good surface water connection but, in contrast, the remaining wetlands depend more on groundwater level. Additionally, there are significant differences in the dynamic within the same wetland. The temporary and spatial variations of the records evidence the importance of continued monitoring and contrasting data with several techniques for a better hydrogeological understanding of the LCS wetland-Motril-Salobreña aquifer system.
