Abstract

In this paper surface bed texture changes both upstream and downstream from check dams are shown for 2 ephemeral channels of the Segura Basin, south-eastern Spain (the Torrecilla and Carcavo catchments), in relation to their degree of in-fill and slope variations. The armoring processes caused downstream from the check dams are studied with regard to the size of the structures, the hydro-dynamic characteristics of the flow and the sediment supply rates. From a comparative analysis of the surface and sub-surface particle sizes the longitudinal armouring trend of the bed along the corrected channels is described. Finally the surface size variation and the changes in roughness are analysed in accordance with the distance from the check dams and the bed slope
