The bifurcation ratio is a fundamental metric in watershed analysis that quantifies how stream networks branch as they increase in order. It reflects the degree of branching and is useful for assessing the homogeneity of a drainage basin.
In the Strahler ordering system, each stream segment is assigned an order (u). The number of streams of a given order (N_u) typically decreases with increasing order. The ratio of N_u to N_{u+1} provides insight into the geomorphological processes shaping the basin.
A higher bifurcation ratio indicates a more highly dissected basin, while lower values suggest a smoother, less branched terrain. This metric is often used in flood forecasting, erosion studies, and land‑use planning.
