  abstract = {{I}n small islands, a freshwater lens can develop due to the recharge induced by rain. {M}agnitude and spatial distribution of this recharge control the elevation of freshwater and the depth of its interface with salt water. {T}herefore, the study of lens morphology gives useful information on both the recharge and water uptake due to evapotranspiration by vegetation. {E}lectrical resistivity tomography was applied on a small coral reef island, giving relevant information on the lens structure. {V}ariable density groundwater flow models were then applied to simulate freshwater behavior. {C}ross validation of the geoelectrical model and the groundwater model showed that recharge exceeds water uptake in dunes with little vegetation, allowing the lens to develop. {C}onversely, in the low-lying and densely vegetated sectors, where water uptake exceeds recharge, the lens cannot develop and seawater intrusion occurs. {T}his combined modeling method constitutes an original approach to evaluate effective groundwater recharge in such environments.},
