Global River Topology (GRIT)
The Global River Topology (GRIT) is a vector-based, global river network that not only represents the tributary components of the global drainage network but also the distributary ones, including mult...

🌎 Unlike existing datasets that simplify rivers into single-threaded, convergent flows based on elevation, GRIT captures both converging and diverging flow patterns — a crucial advance for understanding river systems, especially in flood-prone, densely populated areas.

We’re thrilled to share GRIT, the world’s first high-resolution global river network that maps how rivers both merge and split across the landscape — now published in Water Resources Research (Wortmann et al., 2025).
