"... KEY POINTS:
• River multifurcation pathways were identified in a vector river network globally
• A multifurcation scheme was added to a river network routing model to split river discharge at divergences
• Accounting for multichannels improved discharge accuracy and resulted in earlier arrival of flood waves downstream of divergences…”

[as follow up to my post sharing their work (https://fe9h.short.gy/uncFhK) one of the the authors, Chang Liao, stated “Thanks for sharing our earlier work, which described the HexWatershed 1.0. As of right now, HexWatershed 3.0 is fully mesh-independent, supporting both structured (hexagon, square, latlon) and unstructured (MPAS, DGGrid) meshes. see more details here [^^^^]…”]
