Figure 4—Simulations of tor development.
Model simulations illustrating tor development. Color scale for evolving sediment thickness (called “regolith”) and horizontal scale bar apply to all panels. Here, the lower boundary condition is “open”, with the sediment-elevation there decreasing, representing base-level incision. Simulation uses constant rainfall conditions (64 cm/y). Tors tend to develop along runoff flow paths initially, but their correspondence to preexisting channel incision becomes weak as the system evolves.
