Groundwater influence on soil moisture fields, soil moisture memory and evapotranspiration to the atmosphere is evaluated over the Iberian Peninsula using 10-years simulations of the LEAFHYDRO Land and Groundwater Model. The model respresents gruondwater and and its interactions with the land surface: 1) two-way flux between goundwater and soil above, 2) groundwater lateral flow within the saturated zone, and 3) two-way groundwater-streams exchange. The simulation is validated with observational water table depth and streamflow data. Strong groundwater influence on soil moisture increase, evapotranspiration enhancement and soil moisture memory from past dry and wet periods is found, mostly over shallow water table regions in the Peninsula
