摘要：In the present paper, 8 aerial orthophotographs were used for analysing the evolution of a valley bottom gully andits relationship with land use and vegetation cover in SW Spain. In addition, the growth model observed was compared withthe literature. Results showed an increase in the area affected by gullying during the period by 314m2 and a clear relationshipbetween the areas affected by gullying and land use intensity was found.
