BetaBetaDataset
To evaluate the volume of water required for the preservation of freshwater-dependent ecosystems at a global scale.
The dataset presents a first attempt to estimate the volume of water required for the maintenance of freshwater-dependent ecosystems at the global scale. This total environmental water requirement (presented as a percentage of Mean Annual River Flow - MAR) consists of ecologically relevant low-flow and high-flow components, and depends upon the objective of environmental water management. Both components are related to river flow variability and are estimated by conceptual rules from discharge time series simulated by the global hydrology model.
This dataset entails basin id, country name, number of discharge, major river basin, water stress indicator, and total discharge needed by the environment.
WaterGAP 2 (consists of the Global Water Use Model and the Global Hydrology Model)
