Comparison of traditional river modeling approach and graph-based representation. (a) Conventional one-dimensional river discretization showing uniform reach segments with fixed computational nodes. (b) Graph neural network representation with nodes as adaptive river reaches and edges representing hydraulic connectivity, enabling flexible topology and enhanced information flow.
