RT Journal Article T1 Génesis y evolución de lagunas endorreicas en superficies colgadas por abandono y degradación de una red de drenaje previa: el caso de la Albuera, Badajoz T1 Genesis and evolution of wetlands on perched surfaces as result of the degradation of a previous network due todrainage changes: the Albuera complex, Badajoz A1 Durán Valsero, Juan José A1 Garzón Heydt, Guillermina A1 García de Domingo, Alfredo A1 Muñoz Barco, Pedro A1 Ortega, J.A. A1 Soria, Jesús M. AB Geomorphological and hydrochemical characteristics of the ponds complex of La Albuera is analysed inrelation to their perched position on the «Raña» surfaces. The wetlands are classified as a fluvial controlledcontinental type, favoured also by local subsidence processes. Their origin needs to be related to dewateringcapacity loss allowing ponds preservation on the impervious surfaces, also favoured by subsidence. Thedegradation of the previous drainage pattern is forced by the modern streams shift and incision, and theformer network has not yet been properly captured and integrated by the present river system PB Sociedad Geológica de España YR 2005 FD 2005 LK http://hdl.handle.net/10272/8718 UL http://hdl.handle.net/10272/8718 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
