Description: Rivers primarily derive from World Data Bank 2. Double line rivers in WDB2 were digitized to created single line drainages. All rivers received manual smoothing and position adjustments to fit shaded relief generated from SRTM Plus elevation data, which is more recent and (presumably) more accurate.
Description: The Global Lakes and Wetlands Database was developed through a partnership among WWF, the Center for Environmental Systems Research, and University of Kassel, Germany. It draws upon the best available maps, data and information to display lakes and wetlands on a global scale (1:1 to 1:3 million resolution). The application of GIS functionality enables the generation of a database which focuses in three coordinated levels on (1) large lakes and reservoirs, (2) smaller water bodies, and (3) wetlands.
Level 3 (GLWD-3) comprises lakes, reservoirs, rivers and different wetland types in the form of a global raster map at 30-second resolution. For GLWD-3, the polygons of GLWD-1 and GLWD-2 were combined with additional information on the maximum extents and types of wetlands. Class ‘lake’ in both GLWD-2 and GLWD-3 also includes man-made reservoirs, as only the largest reservoirs have been distinguished from natural lakes.
The data is available for free download (for non-commercial scientific, conservation and educational purposes).
Description: Data downloaded from HydroSHEDS.
HydroSHEDS provides hydrographic information in a consistent and comprehensive format for regional and global-scale applications. These data layers are available to support watershed analyses, hydrological modeling, and freshwater conservation planning at a quality, resolution, and extent that had previously been unachievable in many parts of the world.
It offers a suite of datasets, including stream networks, watershed boundaries, drainage directions, and other data layers such as flow accumulations, distances, and river topology information. Recently available data derived from HydroSHEDS include comprehensive layers of major basins and smaller sub-basins (~100-2,500 km2) across the globe.
HydroSHEDS has been developed by the WWF Conservation Science Program in partnership with the U.S. Geological Survey, the International Centre for Tropical Agriculture, The Nature Conservancy, and the Center for Environmental Systems Research of the University of Kassel, Germany.

Description: The Water Risk Filter aims to cover all relevant aspects of water risks, and uses the best available global data source for each of the indicators. The number of indicators has been rationalized during the development process, balancing the fact that the tool should be practical for non-water experts while still capturing all risk aspects. Furthermore, a number of informative indicators is provided automatically (Basin risk indicators) or by the user via a questionnaire (Company risk indicators) which are not taken into account in the risk calculations.
