  abstract = {{R}eservoir siltation because of water erosion is an important environmental issue in {M}editerranean countries where storage of clear surface water is crucial for their economic and agricultural development. {T}he high density of gully systems observed in {M}editerranean regions raises the question of their contribution to reservoir siltation. {I}n this context, this study quantified the absolute and relative contributions of rill/interrill and gully/channel erosion in sediment accumulation at the outlet of small {T}unisian catchments (0·1-10 km2) during the last 15 years (1995-2010). {T}o this end, a fingerprinting method based on measurements of caesium-137 and total organic carbon combined with long-term field monitoring of catchment sediment yield was applied to five catchments in order to cover the diversity of environmental conditions found along the {T}unisian {R}idge and in the {C}ape {B}on region. {R}esults showed the very large variability of erosion processes among the selected catchments, with rill/interrill erosion contributions to sediment accumulated in outlet reservoirs ranging from 20 to 80%. {O}verall, rill/interrill erosion was the dominant process controlling reservoir siltation in three catchments whereas gully/channel erosion dominated in the other two catchments. {W}e identified the presence of marly gypsum substrates and the proportion of catchment surface covered by soil management/conservation measures as the main drivers of erosion process variability at the catchment scale. {T}hese results provided a sound basis to propose guidelines for erosion mitigation in these {M}editerranean environments and suggested to apply models simulating both rill/interrill and gully/channel erosion in catchments of the region.},
