The existing groundwater abstraction was inventoried and the aquifer system is characterized. Seasonally groundwater recharge at present and in future under different scenarios of climate change were calculated using WetSpass software. Groundwater flow and transportation models were set up to assess the impacts of groundwater abstraction and climate change on groundwater resources (the recharge outputs calculated by WetSpass software were used as inputs for these groundwater models). | Assessment of the impacts of climate change on groundwater resources in Ca Mau peninsula
