Extended Data Fig. 4: Initial steady profile of east and west tributaries and Arun River.
From: Recent uplift of Chomolungma enhanced by river drainage piracy
Initial steady profile of east and west tributaries (a) and Arun River (b). The total amount of incision predicted by the model is the difference between the two profiles in panel b and in Fig. 3b. However, this is only the amount of incision for one combination of model parameters and different incision magnitudes are expected as model parameters change during the iterative process. Comparison of the pre-capture (c) and post-capture (d) Kosi drainage networks. Colours of the trunk (Arun River) and east and west tributaries correspond to Fig. 2. No change is simulated in the planform geometry of the tributaries before or after the capture event. In contrast, the Arun River experiences a sudden increase in upstream drainage area due to capture.
