Runoff Embedding Alignment with VIC Model
The framework learns physically plausible causal graphs that align with established hydrological principles. This includes local forcing-runoff relationships and upstream-downstream routing, offering actionable insights into watershed dynamics.
Case Study: Brazos Basin Routing Graph
CauSTream's learned routing graph for the Brazos Basin closely mirrors the ground-truth river network, capturing main flow directions and subbasin delineations. This demonstrates the model's ability to infer complex spatial dependencies. The graph also highlights long-distance connections that could be further refined with longer lag windows.
