GFLOW 2000, a groundwater flow simulation software, has been used to evaluate magnitude and direction of water exchanges between surface water and groundwater in a plain area (northern Italy). Piezometric levels for steady state conditions have been calculated starting from surface water levels measured in correspondence of 7 hydrometric station located along the considered rivers, using areal precipitation rates. Conjunctive surface water- groundwater solutions have also been computed using a stream network with calculated streamflow. Transitory condition scenarios have been simulated in order to test the code sensitivity in evaluating the effect of intense rainfall on piezometric levels (i.e. the flooding event of 13-16 October 2000) and on water exchanges within the system.

Abstract
GFLOW 2000, a groundwater flow simulation software, has been used to evaluate magnitude and direction of water exchanges between surface water and groundwater in a plain area (northern Italy). Piezometric levels for steady state conditions have been calculated starting from surface water levels measured in correspondence of 7 hydrometric station located along the considered rivers, using areal precipitation rates. Conjunctive surface water- groundwater solutions have also been computed using a stream network with calculated streamflow. Transitory condition scenarios have been simulated in order to test the code sensitivity in evaluating the effect of intense rainfall on piezometric levels (i.e. the flooding event of 13-16 October 2000) and on water exchanges within the system.
