Description :
An EGEM-input data set for 86 ephemeral gullies was collected : detailed measurements of 46 ephemeral gullies were made in intensively cultivated land in southeast Spain (Guadalentin study area) and another 40 ephemeral gullies were measured in both intensively cultivated land and abandoned land in southeast Portugal (Alentejo study area). Together with the assessment of all EGEM-input parameters, the actual eroded volume for each ephemeral gully was also determined in the field. The resulting relationship between predicted and measured ephemeral gully cross-sections is rather weak.
