Country Boundaries | Country Boundaries is a static map showing the country borders taken from the Geographic Information System of the European Commission (GISCO). Important note: the GISCO dataset can be considered authoritative only for the EU28 and EFTA countries. The dataset outside Europe is based on UN GAUL (Global Administrative Unit Layers). The boundaries depicted therein normally (but not always) reflect the UN position. However, GAUL does not have an official authoritative status either, e.g. it is not endorsed by the UN Security Council. There are numerous disputed territories around the world and GISCO does not engage in providing an official position on most of them. Disclaimer: The designations employed and the presentation of material on the map do not imply the expression of any opinion whatsoever on the part of the European Union concerning the legal status of any country, territory or area or of its authorities, or concerning the delimitation of its frontiers or boundaries.

Major river basins | Layer showing major river basins of the world.
| Map | (datasets downloaded in 2023) Please note that Major river basins and LISFLOOD Drainage Network were derived from different elevation datasets, therefore small inconsistencies between the two layers are possible. |
GloFAS lakes and reservoirs | Lakes (the largest 463) and reservoirs (the largest 667) as included in the GloFAS model set up. Selection criteria are:

Flood hazard 100 year return period | Inundated areas for flood events with a return period of 100 years, based on GloFAS climatology. Permanent water bodies derived from the Global Lakes and Wetlands Database and from the Natural Earth lakes map.

LISFLOOD Drainage Network (previously known as Upstream Area) | Drainage network of the LISFLOOD model. Rivers are shown as they are represented in the model. Lines show connections between the model pixels above 250 km2 drainage area. The larger drainage area is represented by both darkening colours and increasing line widths.
The GloFAS river network is plotted with river pixels above 1000 km2, represented by the upstream area (in km2).

Reservoir impact | The map illustrates the potential impact of reservoirs included in GloFAS on river discharge at global scale. To provide a continuous estimate of the potential reservoir effect along river reaches, the ratio of reservoir volume to mean annual discharge was calculated for each grid cell. This ratio makes use of the upstream cumulative reservoir capacity [m3] and the cell-specific total volume of annual natural river discharge [m3].

Administrative Regions | Administrative regions merged using NUTS-2 or NUTS-3 classification from EUROSTAT and the region classification from GADM.
