Efectos de la construcción de pequeñas presas en cauces anastomosados del Pirineo Central

Abstract

In braided streams of pyrenean eocen flysch we ha ve studied the consequences of the building of dams to reduce their torren tia lit y and sediment load. Downstream the capacity of erosion and transport in creases; upstream a spatial arrangement of sedimentary patterns takes place, though the gradient and the presence of longitudinal bars can alter such patterns.
