Water Research & Hydrology

AQUASTAT is the United Nation's global water information system, offering comprehensive data on water resources, use, and agricultural water management across countries. It supports policy-making and research through interactive tools, maps, and downloadable datasets, helping monitor progress toward water-related sustainability goals.

The Climate and Water section of Data.gov provides access to a wide range of datasets related to climate change and water resources, including tools for analyzing impacts on ecosystems, infrastructure, and communities. It supports research, policy-making, and public awareness by offering open data from multiple U.S. government agencies, helping users explore issues like coastal flooding, drought, and water quality.

The U.S. Environmental Protection Agency's Water Data site provides access to a wide range of tools and datasets that support the protection and restoration of U.S. water resources. It includes resources for integrated water analysis, water quality monitoring, drinking water safety, community financing, and restoration efforts, helping professionals and the public make informed decisions about water management.

The United State Geological Survey (USGS) National Water Information System (NWIS) provides comprehensive access to real-time and historical water data from over 1.9 million sites across the U.S., including streams, wells, springs, lakes, and reservoirs. It features interactive tools like the National Water Dashboard and NWIS Mapper, allowing users to explore water flow, quality, and usage data, making it a vital resource for researchers, policymakers, and water managers.

The U.S. Drought Monitor is a weekly map and data tool that tracks drought conditions across the United States using a five-category system ranging from Abnormally Dry (D0) to Exceptional Drought (D4) 1. Developed collaboratively by the National Drought Mitigation Center, NOAA, and USDA, it combines expert assessments and multiple indicators—such as precipitation, soil moisture, and water levels—to inform decision-making, policy, and drought relief programs
