Quantifying hydrologic parameters such as precipitation, streamflow, evapotranspiration,
and aquifer response are fundamental to understanding a region’s hydrological budget, and
thus the availability of water resources. This is particularly important in small island
developing communities where critical water resources are limited. Climate and
streamflow measurements provide information on ground and surface water supply, while
measurement of aquifer parameters such as water level and salinity is imperative for
