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.
WETLANDS AND PROTECTED AREAS

Source RAMSAR sites :https://rsis.ramsar.orgThe 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 UNEPThe 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. Data are regularly updated and Rivers Network is keen to provide as much as possible the most updated published data.

DAMS AND RESERVOIRS
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

GRanD v1.3 ( Global Reservoir and Dam Database (GRanD) )augments v1.1 with an additional 458 reservoirs and associated dams to bring the total number of records to 7320. Most of the added reservoirs were constructed between 2000 and 2016; global reservoir storage is increased by 666.5 km3. Updates have also been made to attribute data originally developed for GRanD v1.1; this includes a new column to indicate whether and when a dam has been removed. Source : Lehner, B., C.

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
