• Resumen

  • Geomorphological and hydrochemical characteristics of the ponds complex of La Albuera is analysed in relation to their perched position on the «Raña» surfaces. The wetlands are classified as a fluvial controlled continental type, favoured also by local subsidence processes. Their origin needs to be related to dewatering capacity loss allowing ponds preservation on the impervious surfaces, also favoured by subsidence. The degradation of the previous drainage pattern is forced by the modern streams shift and incision, and the former network has not yet been properly captured and integrated by the present river system.
