Short summary

Water resource management on volcanic islands is challenging and faces several issues. Taking advantage of new heliborne geophysical technology, correlated with borehole and spring data, we develop a watershed-scale conceptual model and demonstrate that permeability increases with age for the studied formations. Moreover, complex geological structures lead to preferential flow circulations and to discrepancy between topographical and hydrogeological watersheds, influencing river flow rates.
