Over the course of several years, the Global Water Information Interest Group (GWIIG) of the Research Data Alliance focused on topics related to organization, representation, publication, sharing, discovery, re-use and integration of hydrologic information of different types. One of the outcomes of the GWIIG was the creation of a list of web portals and/or websites with data or links to data on water resources. The portals generally provide data that are at a minimum national in scope, and many of the portals offer global data.
The GWIIG requested that CUAHSI host this list to ensure permanence and wider distribution to the community. CUAHSI is continuously adding to the list based on community input. To suggest a web portal, please email help@cuahsi.org.
Users can scroll through the list of portals below, or use the browse and search tools above.
The list is by no means comprehensive. Feedback or information regarding additional portals can be sent to help@cuahsi.org.
An advanced and fast flow forecasting system based on weather and hydrologic modeling for Ganges and Brahmaputra river system.
A monitoring and reporting framework designed to provide a response to and follow-up on the political commitments made concerning water and sanitation at the continental level. Indicator reporting, version 8.0.1
FAO’s global water information system, developed by the Land and Water Division
Long-term, national-scale data including rainfall, drought, and lakes, provided by the Centre for Ecology and Hydrology (UK) including external data resources hosted by CEH
The CUAHSI Data services provide access to data published by individual researchers, citizen science groups and federal data providers through HIS (Hydrologic Information system and Hydroshare. Please access data through our portals http://data.cuahsi.org and http://www.hydroshare.org
The WCI portal takes data that you select and plots it on a map to help you analyse, export and share it.
Article on water statistics in the European Union based on data on freshwater resources, water abstraction, water use and wastewater treatment and disposal. Links to the main tables and the database on water.
A platform offering links to data, maps, tools and other resources relating to freshwater resources and their biodiversity.
GEMStat provides water quality data of ground and surface waters within the scope of the GEMS/Water Programme.
Entry point for earth observation data implemented and operated by the European Space Agency. (Note that most data are not water-related.)
GEMS/Water works to: ensure water quality data flows from a world-wide network, maintain the global water quality database (GEMStat), and enable countries to deliver authoritative data through capacity development.
An experimental system to detect and map in near-real time major river floods based on daily passive microwave satellite observations.
GGIS is an interactive, web-based portal to groundwater-related information and knowledge.
The GMOS Spatial Data Infrastructure (SDI) was developed in order to assure a timely and up-to-date sharing of information on mercury in the environment, including humans. (Note that most data are not water-related.)
The Global Rivers Observatory (led by the Woods Hole Research Center and the Woods Hole Oceanographic Institution) investigates river chemistry in Earth’s most significant river systems. It is active in 18 watersheds around the world and measures the chemical composition of rivers near their entry points to the ocean.
