HydroATLAS represents a global compendium of hydro-environmental sub-basin and river reach characteristics derived from existing global datasets at 15 arc-second resolution.

HydroATLAS is a comprehensive database gathering and presenting a wide range of hydro-environmental attributes from existing global datasets in a consistent and organized manner. HydroATLAS is divided in two datasets, BasinATLAS and RiverATLAS, which represent sub-basin delineations (polygons) and the river network (lines), respectively. HydroATLAS offers attributes organized in seven categories: hydrology; physiography; climate; land cover & use; geology & soils; and anthropogenic influences.

HydroATLAS provides a consistent and organized presentation of over 50 hydro-environmental variables, partitioned into more than 250 individual attributes, that are derived from recent published sources. The hydro-environmental attributes are organized into six categories: hydrology and hydrography; physiography; climate; land cover and land use; geology and soils; and anthropogenic influences and demographics. HydroATLAS derives these hydro-environmental attributes for river reaches and hierarchically nested watersheds at multiple scales.

HydroATLAS is currently under development and an associated publication is under review. Data release is anticipated for summer 2019. For more information, please refer to our current draft versions of the Technical Documentation and the associated BasinATLAS Catalog and RiverATLAS Catalog, respectively.
