Hydrologic Monitoring Network Handbook

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
understanding sub-surface water flow, transport, and availability. These hydrologic
datasets are essential for design of sustainable water supply systems and for prediction or
detection of acute threats to drinking water quality or availability.
