Abstract: The coastal aquifer system is highly susceptible to seawater intrusion, and numerical simulation of this phenomenon is a reliable approach for sustainable management. This paper presents a fuzzy uncertainty analysis of the Henry Problem, a well-known benchmark case for studying saltwater intrusion in coastal aquifers. Fuzzy functions are employed to capture the inherent uncertainty associated with input parameters, and the uncertainty in saltwater intrusion is calculated, using a simulation-optimisation tool. The optimization tool will calculate the minimum and maximum possible values of total saltwater, considering uncertain input parameters. The preliminary results for Henry's problem show that small uncertainties in input parameters could significantly affect seawater intrusion.
