Description: Department of Projects and Rural Engineering, Public University of Navarre, Los Olivos Building, 31006 Pamplona, Spain. Many of the researches on (ephemeral) gully erosion comprise the determination of the geometry of these eroded channels specially width and depth. This is not a simple task due to uncertainty generated by the wide range of variability of gully cross-section shape found in the field. However in the literature this uncertainty is not recognized and then no criteria in the measurement procedure is indicated. The aim of this work is to make the researchers aware of the ambiguity that arises when characterizing the geometry of an ephemeral gully and similar eroded channels. Besides, a measurement protocol is proposed with the ultimate goal of pooling criteria in future works. It is suggested to characterize the geometry of a gully through its effective width and effective depth, which, together with its length, define an equivalent prismatic gully (EPG). The latter would facilitate the comparison between each other of different gullies.
