  abstract = {{A}n intensive monitoring investigation was conducted within the {K}amech catchment ({C}ape {B}on, {T}unisia) to document the effect of scale on the hydrological and erosive responses in a {M}editerranean climate regime with cracking soils. {A}n evaluation of the individual contribution of topsoil and gully processes to total sediment delivery at different spatial scales was also conducted. {C}ontinuous runoff and erosion measurements during a 7-yr period at four nested gauging stations were examined in a plot ({P}1; 1.32 ha), a plot + gully ({P}2+{G}; 1.37 ha), a micro-catchment ({MC}; 15.2 ha), and the entire catchment ({C}; 263 ha). {D}ata analysis showed a high interannual variability and contribution of only a few events; three major events generated approximately 20% of the total runoff and at least 50% of the total erosion at all of the monitoring stations. {T}he results also highlight the strong seasonal dynamics of both water and sediment delivery, with a time lag observed between runoff and sediment responses. {T}he presence of open cracks in autumn was identified as a main factor explaining this time lag. {A} constant monthly and annual specific runoff response was observed among the stations, and a simple linear model combining a single rate of topsoil (17 t ha(-1) yr(-1)) and gully (80 t ha(-1) yr(-1)) erosion (weighted by their contribution area) successfully predicted the differences observed in the mean annual erosion rates among the stations. {F}inally, this work showed the predominance of topsoil erosion processes in a {M}editerranean catchment that is characterized by cracking soils and very high hydro-sedimentary connectivity.},
