The sea-floor morphology of a Mediterranean shelf fed by small rivers, northern Alboran Sea margin

Shelf sediment by-pass is a likely process during the Holocene in the eastern shelf, as suggested by the identification of two types of submarine valleys: (1) numerous gullies occur from the distal toe of the Guadalfeo River prodelta to the slope; (2) submarine canyon heads affect to the Holocene sedimentary wedge in the eastern sector of the study area. In the western shelf, however, the influence of shelf sedimentation processes on deeper domains is minimal, due to shelf widening, prevalence of relict features and absence of submarine valleys.
