Open research infrastructure

Open data for
river-centric hydrology.

We develop and contribute reusable datasets that make river systems more observable, spatially explicit, and accessible to the hydrology community — from global river networks and naturalized discharge to dynamic catchment attributes and geomorphic floodplains.

River network · Local catchments Data access forthcoming

MERIT-Basins

Global vectorized flowlines and local catchments with a 25 km² channelization threshold, providing a consistent spatial framework for river-network analyses.
