Marker lines prior to (a) and after 750 years of flow of (b) isotropic and (c) anisotropic ice. The axial plane of the resulting shear fold in isotropic ice mimics the bedrock topography, while it is controlled by shearing along a horizontal shear zone in the case of anisotropic ice. Green: bedrock, flow to the right.

Our simulations produce catchment areas, river lengths, and volumes of deposited sediment that are consistent with the ranges observed in continental-scale deltas such as the Mississippi and Amazon rivers. (a) Example showing the outputs from the numerical simulation showing the elevation and bathymetry (top) and cumulative flexure (bottom). Model dimensions are 4500 km x 2000 km, with a vertical exaggeration of 100x. (b) Scatter plot of river length (top) and 405 shelf width (bottom) versus catchment area from river systems. Data is from Somme et al. (2009), Nyberg et al. (2018), Blum et al. (2013, 2017) and simulations presented in this study. Pal= Paleocene, Oli=Oligocene, PM= Paleo-Mississippi. (c) Example of synthetic stratigraphy from a simulation without (left) and with flexural compensation (right).
