Hydrogeology of Diego Garcia
- This chapter discusses the hydrology of Diego Garcia. Diego Garcia is particularly relevant to the study of island hydrology for several reasons: (1) The effects of aquifer layering on groundwater salinity and tidal response can be described in detail, (2) groundwater withdrawal is unusually large for an atoll, (3) the water supply has a 17-year operating history that shows distinct dry-season increases in salinity, and (4) the 44-year rainfall record contains interannual and even decadal periods of persistently wet and dry climate. Much of the knowledge gained at Diego Garcia is readily transferrable to other small islands. Early exploratory studies provide interesting views of aquifer tidal response and a freshwater lens _truncated? by aquifer layering. The present water-production system is unparalleled for such a small island, and the low salinity of pumped water has validated the development strategy of numerous, widely spaced wells and low pumping rates.
