Each animation frame depicts a 1000-yr model time step. The grid view shows the erosional wave following fault throw that occurred at 0 yrs elapsed time in the animation. The cells coloured blue overlap the stream channel depicted in the longitudinal profile. The upper limit of streams were set by the critical drainage area factor described in the paper. The knickpoint location along the selected profile was updated at each time step following Eq. 6 in the paper. The profile crosses the fault and a closed basin that formed immediately after fault slip. The stream along the lower profile first integrates the closed basin and then the profile headwaters areas atop the uplifted right block.
