Abstract
En este estudio se presenta una síntesis de los resultados de la
monitorización hidrológica de 5 lagunas peridunares de la Reserva
Biológica de Doñana durante el período 2020-2023. Los datos de
nivel y temperatura derivan del registro de sensores instalados en las
cubetas lacustres y piezómetros adyacentes. Asimismo, se incluye el
registro en uno de los sondeos de abastecimiento de Matalascañas
y las medidas de conductividad eléctrica del agua que se tomaron
durante el periodo de estudio. Los resultados muestran una disminución en el nivel de agua y cambios en el hidroperiodo de las lagunas en los tres últimos años, relacionados con el módulo anual y la
distribución de las precipitaciones. La temperatura del agua experimentó un aumento notable en las lagunas durante el periodo de
estudio. En este estudio se constata la disminución del hidroperiodo
y su impacto en las propiedades fisicoquímicas del agua en las lagunas peridunares del Parque Nacional de Doñana. Por otra parte,
se evidencia la necesidad de la monitorización de detalle de estas
variables hidrológicas para la gestión sostenible del acuífero de Doñana, en el contexto actual de cambio climático
This study presents a synthesis of the results from the hydrological monitoring of the sand ponds in the Doñana Biological Reserve during the period 2020-2023. Data on water level and temperature are derived from records from sensors installed in 5 ponds’ bottom and neighboring piezometers. Additionally, this includes records from one of the Matalascañas supply wells and water electrical conductivity measurements taken throughout the study period. The results show a decrease in water level and changes in the hydroperiod of the ponds over the last three years, related to the annual module and the distribution of precipitation. The water temperature showed a significant increase in the ponds during the study period. This study demonstrates the alteration of the water regime and its impact on the physicochemical properties of the water of the Doñana National Park sand ponds. On the other hand, it highlights the need for detailed monitoring of these hydrological variables for the sustainable management of the Doñana aquifer, in the current context of climate change
