Resumen:
evolution of gullies on the foredune of Pehu´en Co, Argentina, was explained using a combination of satelliteimages analysis and UAV models. In 16 years, the area covered by gullies increased 2011.4 m2 (5.6 times in size).The runoff due to precipitation is the major natural erosive agent affecting the active gully field, and itsexpansion is related to annual rainfall and the recurrence of rainy days. However, man-originated elementschanged the drainage network and modified gully development, mainly by the construction of an unpaved road.The influence of the installation of Big Bags at the foredune toe, artificial nourishment, and the use of gullies asdescents to the beach are also evaluated. Intervention is needed at gully incisions, mainly at the head of thecatchments and early stages, particularly where the mass movement and the generation of cliffs have alreadybegun. There is also a need to evaluate the location of road drainage to both reduce gully expansion and thecreation of newer ones.
