Reflexión sobre dinámica morfosedimentaria. Implicaciones para la gestión fluvial en un contexto de cambio global
Resumen
Este artículo presenta un breve estado de la cuestión sobre la dinámica morfo-sedimentaria en ríos y los principales impactos, y una serie de reflexiones sobre las posibles implicaciones que el conocimiento adquirido hasta la fecha pueda tener para la gestión fluvial, todo ello en un marco de cambio global (clima, usos del suelo). La conservación de la estructura y el funcionamiento de los cauces fluviales y, en su caso, su restauración se debe sustentar en un profundo conocimiento de los procesos físicos que en ellos tienen lugar y el nexo de unión con la cuenca de drenaje. En este sentido es importante avanzar en el análisis detallado de los componentes morfodinámicos y sedimentarios claves que permitan definir, por ejemplo, umbrales de cambio irreversibles en medios fluviales poco o no alterados y programas de reconexión lateral y longitudinal en medios muy alterados, todo ello encaminado a la consecución del mejor estado ecológico y de conservación de los ecosistemas fluviales.
