  abstract = {{F}uture climate scenarios for the {M}editerranean region indicate a possible decrease in annual precipitation associated with an intensification of extreme rainfall events in the coming years. {A} major challenge in this region is to evaluate the impacts of changing precipitation patterns on extreme hydrological events such as droughts and floods. {F}or this, it is important to understand the impact of climate change on soil moisture since it is a proxy for agricultural droughts and the antecedent soil moisture condition plays a key role on runoff generation. {T}his study focuses on 10 sites, located in {S}outhern {F}rance, with available soil moisture, temperature, and precipitation observations on a 10 year time period. {S}oil moisture is simulated at each site at the hourly time step using a model of soil water content. {T}he sensitivity of the simulated soil moisture to different changes in precipitation and temperature is evaluated by simulating the soil moisture response to temperature and precipitation scenarios generated using a delta change method for temperature and a stochastic model ({N}eyman-{S}cott rectangular pulse model) for precipitation. {R}esults show that soil moisture is more impacted by changes in precipitation intermittence than precipitation intensity and temperature. {O}verall, increased temperature and precipitation intensity associated with more intermittent precipitation leads to decreased soil moisture and an increase in the annual number of days with dry soil moisture conditions. {I}n particular, a temperature increase of +4 °{C} combined with a decrease of annual rainfall between 10 and 20 %, corresponding to the current available climate scenarios for the {M}editerranean, lead to a lengthening of the drought period from {J}une to {O}ctober 15 with in average +22 days of soil moisture drought per year.},
