The main source of livelihood in the Demre plain is greenhouse agriculture and the irrigation water demand is provided by groundwater. Groundwater level is affected by the use of groundwater over time in Demre coastal aquifer. The security of long term water and food production in the plain depends on sustainable use of the alluvium aquifer. In this study, groundwater level is measured at 24 wells located in Demre plain between January 2014 - May 2015 for 6 periods. In addition, electrical conductivity-temperature-level measurements are taken in 4 wells at different periods by automatic data-loggers. When data obtained from the data-loggers are associated with the daily precipitation data, it is determined that groundwater level increases after the precipitation in all wells. The long-term groundwater level rise continuation shows that alluvium aquifer feds firstly by precipitation over aquifer and then later seepage from limestone. When the change of the specific electrical conductivity of groundwater in the Demre coastal aquifer is examined over time, there is no significant change in conductivity in some wells during the year, while in some cases it is determined that there is diluted in groundwater ion concentration when precipitation reached the ground directly or with a short infiltration. In this study, it is determined that Demre coastal aquifer which is fed by precipitation and lateral seepage has quasi steady-state groundwater level in long term. This indicates that aquifer storage is not changed.
