► We clarify hydrologic features of a coastal lagoon with sporadic outflow to the ocean. ► We estimate the water budget of the lagoon under closed condition. ► Confined groundwater outflow to ocean through the sand bar controls the budget. ► The confined aquifer is likely to exist at the similar ele...
