Resum

In an abandoned farmland catchment the eroded areas have been mapped in order to locate the possible sediment sources. Besides large, non functional mass movements, three types of processes and geoforms stand out: small debris flows, areas where sheet wash erosion prevails and scars located in the taluses flanking the main ravine. Fieldwork and the first results obtained on sediment transport at the outlet of the catchment suggest that the sediment contributing area, representing less than 1 percent of the basin, is mostly the channel itself and its taluses. © 1997 Published by Elsevier Science Ltd.
