Webchannel pattern. Models based on linearized physics-based equations [18–21] and 2D nonlinear physics-based morphological models [22–25] have been established to simulate the braided channel evolution. Cellular models [26–29], 2D and 3D flow-sediment numerical models [30–35] have been developed to model braided rivers. Web16 dec. 2013 · Braided rivers represent one of three main channel types. In Northern Eurasia up to 35% of total river length is characterized by this pattern (Chalov 2008; Alexeevsky et al. 2013).The total length of braided rivers in Russia accounts for 40% of the inland waterways and up to 57–62% of waterways in Siberia.
