On the left is a schematic illustrating the model setup in an idealized rectangular channel. On the right is a contour plot of predicted ratio of lateral erosion rate to vertical erosion rate as a function of transport stage and relative sediment supply.

Impacts by Moving Gravel Cause River Channels to Widen or Narrow

by Mikaël Attal 24 September 202115 February 2023

A new analytical model describes how the amount and grain size of sediment transported by rivers influences bedrock channel width, which can be used to predict where rivers will widen or narrow.

Meteoric ¹⁰Be Reveals Lithological Control on Erosion Rates

by Mikaël Attal 1 June 202026 January 2023

New meteoric ¹⁰Be data quantify fast erosion of slates in the Zhuoshui River catchment in Taiwan and demonstrate the influence of lithology on landscape steepness.
