info:eu-repo/semantics/conferenceObject,
The discovery of very young gully systems on Mars has occasioned a lively debate about the processes and materials involved in their formation (Malin and Edgett, 2000). The strong interest in these features results because ...
Agricultural land use, piping and gullies activity in the Huelva lower valley (Saragossa, Spain)

info:eu-repo/semantics/conferenceObject,
The variations in the total amount of surface used for
arable crops both for dry farming and fallow land, with
regard to the different “agricultural policies”, have modified
the natural dynamics of some processes such ...
Surfaces of gullies generated by piping process in abandoned fields (south-east of Spain)

info:eu-repo/semantics/conferenceObject,
The piping process have an important development in old
agricultural terraced fields. The abandonment of these
fields, together with the lithologies, hydraulic and climatic

The importance of the presence of gullies in the production of sediments in semiarid areas (Murcia, south-east of Spain)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The study has shown how the existence of gullies
remarkably increases the rates of erosion and, therefore, the
volume of sediments that arrives at the dikes of hydrological
correction. A consequence of this is the need to ...
