Filling of sedimentary basins involves the interplay of external and intrinsic controls, which operate over vastly different spatial and temporal scales. Here, we present computer simulations of complete, source-to-sink, sediment transfer from mountains to depositional basins. Simulations quantify the spatial and temporal effects of external and intrinsic controls on sediment erosion, transport, and deposition in four different sediment-routing scenarios defined by a combination of systems with large or small rivers flowing to wide or narrow continental shelves. These experiments inform predictions of stratigraphic preservation, architectural style, and lithologic variability across complete source-to-sink sedimentary systems.
