This database provides access to discharge data from the original UNESCO river archive in a digital format for use by researchers and planners in the water sciences community. While this is a very good global resource, it does not present information on rivers in the United States. Full description.

This USGS site allows students to access a variety of streamflow information. There is an interactive map where the user can select streamflow data for selected stream gaging stations in the United States. Stations can be selected in list form, an interactive state map, or 10 nearest stations to position selected. Each retrieval form allows the user to refine their data search through predefined displays, ... Full description.

The National Water Information System (NWISWeb) provides real-time and historical data on water flow, water levels, and water quality for approximately 1.5 million sites in all 50 States, the District of Columbia, and Puerto Rico. The types of data collected generally fit into the broad categories of surface water and ground water. Surface-water data such as gage height (stage) and stream flow (discharge) ...

This online collaborative project is part of the Center for Improved Engineering and Science Education (CIESE) program, which has developed internet activities for the elementary, middle, and high school level student. Based on data collected by their household members and their classmates, students determine the average amount of water used by one person in a day. They compare this to the average ...

As part of its Water Science for Schools site, the US Geological Survey defines industrial water use and includes several tables and maps showing where and how industry uses water. Students and teachers can look at their state and see 1990 data for how much ground water and how much surface water is used in industry as well as how much of that water is fresh or saline.

Robowell is an automated process for monitoring selected ground-water-quality properties and constituents. It was developed to provide a cost effective monitoring system that met protocols expected for manual sampling. Users have access to real-time water quality data. There are also links to other water quality sites. Full description.

The MYPond project is an investigation of the chemical reactions, biological processes and inflow/outflow balances found within a pond environment. Instrumentation has been established in two ponds near each other so that a variety of chemical and physical properties are measured at various depths at 15-minute time intervals. Data can be viewed either in real-time or accessed from an archive, and ... Full description.

NOAA's Paleoclimatology Program is working with scientists from around the world to study past climate in hopes of achieving a better understanding of the Earth's present and future climate. This site was developed to help educate, inform and highlight the importance of paleoclimate research; as well as to show how paleoclimate research relates to global warming and other important issues of climate ...
