The salinity, depth, quantity, and reliability of fresh 
ground-water resources on coral reef islands and coastlines 
are environmentally important parameters. Groundwater 
influences or controls the terrestrial flora, salinity, and 
nutrient levels in the near-shore benthic environment, the 
rate and nature of sediment diagenesis, and the density of 
human habitation. Data from a number of Indo-Pacific reef 
islands suggest that freshwater inventory is a function of 
rainfall and island dimensions. A numerical model (SUTRA) has 
been used to simulate the responses of atoll island 
groundwater to changes in recharge (precipitation), sea 
level, and loss of island area due to flooding.
