Abstract
New high-quality high-resolution bathymetric data along the northeastern slope of the
Gulf of Cadiz continental margin reveals three gullies fields. The morphological and morphometric
features of these gullies have been studied. The following morphometric variables have been
measured in every gully in order to make a quantitative morphological analysis: width, depth,
thalweg length, straight line length, area, sinuosity index, width/depth ratio, and stream order. The
morphological characterization of the gullies suggests that these morphologies vary with the local
physiography (concavity/convexity of the slope), the sediment transport efficiency, tectonic control
and oceanographic regime.
