Evaluating the relationship between meander‐bend curvature, sediment supply, and migration rates

River meander migration plays a key role in the unsteady ‘conveyor belt’ of sediment redistribution from source to sink areas. The ubiquity of river meandering is evident from remotely sensed imagery,…

The stratigraphic evolution of a submarine channel: Linking seafloor dynamics to depositional products

We investigate the relationship between the cross-sectional geomorphic expression of a submarine channel as observed on the seafloor and the stratigraphic product of long-lived erosion, bypass, and se…

How do basin margins record long-term tectonic and climatic changes?

A long-standing goal of sedimentary geoscience is to understand how tectonic and climatic changes are reflected in basin fill. Here, we use 14 numerical models of continental-scale sedimentrouting sys…

Grain-Size and Discharge Controls on Submarine-Fan Depositional Patterns From Forward Stratigraphic Models

Submarine fans are important components of continental margins; they contain a stratigraphic record of environmental changes and host large accumulations of oil and gas. The grain size and volume of s…

Submarine channels ‘swept’ downstream after bend cutoff in salt basins

Channel‐bend expansion and downstream translation, as well as vertical movements by aggradation and incision, set the stratigraphic architecture of channelized depositional systems. Early work on subm…
