Resumen
[ES] Los embalses de Doña Aldonza, Pedro Marín y Puente de la Cerrada, situados
en el tramo alto del río Guadalquivir, fueron construidos en la década de los
años 50 y 60. Desde entonces han experimentado un proceso de aterramiento
hasta encontrarse hoy en día colmatados prácticamente en su totalidad.
Mediante este trabajo se ha descrito la evolución morfosedimentaria del
proceso de aterramiento del embalse de Doña Aldonza, el de mayor capacidad
de los tres embalses, mediante ortofotografías aéreas y cálculo de parámetros
relacionados con la generación de sedimentos en la cuenca vertiente y
posterior transporte al embalse. Con estos datos se ha deducido que el
proceso de colmatación del embalse de Doña Aldonza se produjo
mayoritariamente entre los años 1960 y 1980, afectando muy negativamente a
los fines de explotación por el cual el embalse fue ejecutado.
[EN] Reservoirs Doña Aldonza, Pedro Marin and Puente de la Cerrada, located in the upper reaches of the Guadalquivir river, were built in the decade of the 50s and 60s. Since then they have undergone a process of silting up now found almost entirely silted. Through this work described the morphological evolution of sedimentary process of silting of the reservoir of Doña Aldonza, with the largest capacity of the three reservoirs, using aerial orthophotos and calculation of parameters related to the generation of sediment in the reservoir basin and subsequent transport to the reservoir. With this data has been deduced that the process of silting of the reservoir of Doña Aldonza occurred mostly between 1960 and 1980, negatively affecting negatively affecting the targets of exploitation that led to the construction of the reservoir.
