英文摘要:
It is known that the erosion process triggered by gullies contributes to significant soil loss and land degradation, and this can limit the options for the occupation and development of a territory in terms of the suitability and quality of the farmland area. The variety of physical factors associated with gully formation hinders straightforward interpretations and requires well-grounded analysis based on local observation.
This work presents an example of gullies formed in a colluvial hill-slope agricultural area in Seiros, North of Portugal. The gullies were formed by intense rainfall events in 2015 that led to a channel overflowing. The channel in question was 49 m long, 0.50 m wide and 0.50 m deep and had been built by the landowner to protect his farmland from hillslope drainage. The adequacy of the strategy implemented to prevent gully formation with a view to the rehabilitation of the area is validated.
