Abstract
El manantial del Charco del Moro se localiza en el lecho del río
Guadiaro, en el extremo meridional de la garganta de las Buitreras.
Por su ubicación, es extremadamente complicado determinar su
caudal, especialmente durante las épocas de crecida. En este trabajo
se han analizado los registros de caudal en las estaciones de aforo
de los ríos Guadiaro y Hozgarganta y se han calculado los caudales
derivados del río y los infiltrados en los sumideros de la garganta
fluvial para estimar el caudal medio del manantial y el origen de sus
aguas. A pesar de la incertidumbre de los resultados, se ha calculado
un caudal medio próximo a 4 m3
/s, una cifra sensiblemente superior
a la considerada hasta la fecha. Para justificar estos caudales debe
asumirse que los aportes proceden principalmente de las calizas jurásicas del sector meridional de la sierra de Líbar y de la sierra del
Endrinal, lo que implicaría un área de recarga con una superficie
próxima a los 83 km2
The Charco del Moro spring is located in the streambed of the Guadiaro River, at the southern end of the Buitreras Gorge. Due to its location, it is extremely difficult to measure its flow, especially during periods of flooding. In this work, the flow records at the gauging stations of the Guadiaro and Hozgarganta rivers have been analyzed and the flows diverted from the river and those infiltrated in the sinkholes of the streambed have been calculated to estimate the average discharge of the spring and the origin of its waters. Despite the uncertainty of the results, an average flow rate close to 4 m3 /s has been calculated, a figure significantly higher than that considered to date. To justify this flow it must be assumed that the contributions come mainly from the Jurassic limestones of the southern part of the Sierra de Líbar and the Sierra del Endrinal, which would imply a recharge zone with a surface area close to 83 km2
