  abstract = {{S}hrink-swell soils, such as those in a {M}editerranean climate regime, can cause changes in terms of hydrological and erosive responses because of the changing soil water storage conditions. {O}nly a limited number of long-term studies have focused on the impacts on both hydrological and erosive responses and their interactions in an agricultural environment. {I}n this context, this study aims to document the dynamics of cracks, runoff and soil erosion within a small {M}editerranean cultivated catchment and to quantify the influence of crack processes on the water and sediment supplied to a reservoir located at the catchment outlet using water and sediment measurements at a cultivated field outlet as baseline. {D}etailed monitoring of the presence of topsoil cracks was conducted within the {K}amech catchment ({ORE} {OMERE}, {T}unisia), and runoff and suspended sediment loads were continuously measured over a long period of time (2005-2012) at the outlets of a field (1.32 ha) and a catchment (263 ha). {A}nalysis of the data showed that topsoil cracks were open approximately half of the year and that the rainfall regime and water table level conditions locally control the seasonal cracking dynamics. {T}opsoil cracks appeared to seriously affect the generation of runoff and sediment concentrations and, consequently, sediment yields, with similar dynamics observed at the field and catchment outlets. {A} similar time lag in the seasonality between water and sediment delivery was observed at these two scales: although the runoff rates were globally low during the presence of topsoil cracks, most sediment transport occurred during this period associated with very high sediment concentrations. {T}his study underlines the importance of a good prediction of runoff during the presence of cracks for reservoir siltation considerations. {I}n this context, the prediction of cracking effects on runoff and soil erosion is a key factor for the development of effective soil and water management strategies and downstream reservoir preservation.},
