River Network Routing And Discharge Partitioning On A Multichannel River Network
--
https://doi.org/10.1029/2025WR041417 <-- shared paper
--
"... 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…”
