Modeling the Impact of Climate Change in A Mediterranean Catchment(Merguellil,Tunisia)

Climate change impact studies on hydrologic regime have been until recently restricted mainly because of the coarse spatial and temporal resolution of the Global Circulation Models(GCMs)outputs. Nevertheless,local meteorological variables can be derived from GCMs scenarios using downscaling techniques.In the present study,the Statistical DownScaling Model(SDSM)was selected for
