Downdip component of strain rate tensor and resolved stress difference from the numerical model, focusing on features within the plate/slab. The resolved stress difference is defined as ($\sigma_{s} - \sigma_{z}$), where $\hat{s}$, and $\hat{z}$ are unit vectors in the downdip and slab normal directions. The fields show, for example, shortening/extension in the downdip direction. Stress profiles at four locations are shown. The blue line ($x_0$) is the first zero crossing based on analysis of the flexural component of the topography. The black line is the location of maximum bending moment.

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).
