Excerpt from GEOSS *Strategic Plan:
Earth observations for water availability and quality should include measurements of the fluxes and storage of water in a watershed and its underlying aquifer system; precipitation, streamflow, lake and reservoir storage, water quality, evaporation and transpiration, soil moisture, groundwater storage, ground-water recharge and discharge, and withdrawals for various uses should all be measured. Snowfall is of particular interest to water-resources managers because of the seasonal storage of water in the snowpack. Water quality concentrations and loads of various significant natural and anthropogenic contaminants must also be measured to determine their impact on water availability and on aquatic habitats in freshwater, estuarine, and marine environments. Most of these measurements must be made using in situ sensors, sampling, and manual measurement techniques, with only some available from remote-sensing. Temporal variability and long-term trends in these measures of availability must be recorded and documented.
