STREAMS (GloRIC data base - Version 1.0)

Source GloRIC data : https://www.hydrosheds.org/page/gloric

GloRIC is part of the WWF HYDROSHED project. Version 1.0 of GloRiC provides a hydrologic, physio-climatic, and geomorphic sub-classification, as well as a combined type for every river reach, resulting in a total of 127 river reach types. It also offers a k-means statistical clustering of the reaches into 30 groups. The dataset comprises 8.5 million river reaches with a total length of 35.9 million km.

In this website, we have classified rivers by Q average in m3/s.


RAMSAR - Convention on Wetlands

Source RAMSAR sites :https://rsis.ramsar.org

The Convention on Wetlands, called the Ramsar Convention, is an intergovernmental treaty that provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources.

Protected areas -Protected planet

Source "Protected Areas" :World Database on Protected Areas (WDPA), a join project of IUCN and UNEP - March 2018

The World Database on Protected Areas (WDPA) is the most comprehensive global spatial dataset on terrestrial and marine protected areas. Protected areas are internationally recognised as major tools in conserving species and ecosystems, and up to date information on protected areas is essential to fully enable conservation and development activities.

Natura 2000 (EU countries)

Source "Lakes (HydroLAKES data base v 1.0)" :HydroLAKES Version 1.0.

HydroLAKE is part of the WWF HYDROSHED project. HydroLAKES is a database aiming to provide the shoreline polygons of all global lakes with a surface area of at least 10 ha. Additional attributes for each of the 1.4 million lakes include estimates of the shoreline length, average depth, water volume and residence time. All lakes are co-registered to the global river network of the HydroSHEDS database via their lake pour points.

In this website, we display various data. Reference may be found in the HydroLAKE documentation : HydroLAKE documentation

These data were treated afterwards by Rivers Network to fit with river basin limits and formated for web maps purposes. The density ranking is based on the DN values from SEDAC data base.

Baseline Water Stress :  Baseline water stress measures total annual water withdrawals (municipal, industrial, and agricultural) expressed as a percentage of the total annual available blue water. Higher values indicate more competition among users. Sources: WRI Aqueduct; FAO AQUASTAT; NASA GLDAS-2; Shiklomanov and Rodda; Flörke et al.; Matsutomi et al.

Flood Occurrence : Flood occurrence is the number of floods recorded from 1985 to 2011. Source: Brakenridge, Dartmouth Flood Observatory

Groundwater Stress : Groundwater stress measures the ratio of groundwater withdrawal relative to recharge rate; values above one indicate where unsustainable groundwater consumption could affect groundwater availability and groundwater-dependent ecosystems. <br><br>Source: Gleeson, Wada, Bierkens, and van Beek

Upstream Protected Land : Upstream protected land measures the percentage of total water supply that originates from protected ecosystems. Higher ratios indicate higher amounts of runoff originating from upstream areas that are protected under conservation easements. Modified land use can affect the health of freshwater ecosystems and have severe downstream impacts on both water quality and quantity. Sources: WRI Aqueduct; NASA GLDAS-2; IUCN, UNEP
