Palavras-chave: | Gully erosion; Soil degradation; Seirós (North of Portugal); Strategy to prevent gullies | Data: | 2019 | Editora: | Elsevier | Projeto: | FCT-UID/ECI/04028/2013 | Título da revista, periódico, livro ou evento: | Physics and Chemistry of the Earth, Parts A/B/C | Volume: | 109 | Resumo: | 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 Seirós, 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. | URI: | https://hdl.handle.net/10316/88922 | ISSN: | 14747065 | DOI: | 10.1016/j.pce.2018.09.006 | Direitos: | embargoedAccess |
