a Relationship between advection velocity and normalised divide location. Vr is the velocity at the edge of the negative side. b No advection. Uplift rate increases linearly from the bottom edge of 0.5 mm/year to 1 mm/year at the top edge, with an uplift gradient of 0.01 mm/year per km. This simulation belongs to the 20 numerical models in Fig. 2e. c Uniform uplift rate of 0.5 mm/year. Advection towards the top side, and advection velocity decreases linearly from the bottom edge of 1 mm/year to 0.5 mm/year at the top edge, with a velocity gradient of 0.01 mm/year per km. d Uplift gradient and advection push the divide in the same direction. Uplift rate increases linearly from the bottom edge of 0.5 mm/year to 1 mm/year at the top edge, with an uplift gradient of 0.01 mm/year per km. Advection towards the top side, and advection velocity decreases linearly from the bottom edge of 1 mm/year to 0.5 mm/year at the top edge, with a velocity gradient of 0.01 mm/year per km. e Uplift gradient and advection push the divide towards different directions. Uplift rate increases linearly from the bottom edge of 0.5 mm/year to 1 mm/year at the top edge, with an uplift gradient of 0.01 mm/year per km. Advection towards the bottom side, and advection velocity decreases linearly from the top edge of 1 mm/year to 0.5 mm/year at the bottom edge, with a velocity gradient of 0.01 mm/year per km.
