leads to more river bifurcation. This then leads to increased numbers of distributaries in deltas.

Delta bifurcation has a typical angle at which it is observed, with a critical angle of approximately 72º. However, observations and experiments show that many distributary channel bifurcations do not actually exhibit a bifurcation angle of 72º, but rather grow towards this angle over time after initiation of bifurcation. This implies that bifurcations that occur in deltas are semi-permanent, as many observed channels do not exhibit this
