Point Bars

A frozen history of meandering: Mapping and modeling ice-wedge polygons on point bars

A number of meandering rivers in the Arctic, especially in Siberia, have point bars with strikingly structured permafrost polygon patterns. We use a Unet-type convolutional neural network to map the polygons.

Autogenic translation and counter point bar deposition in meandering rivers

This paper explores the development of counter point bars in meandering rivers through autogenic translation processes.

The three-dimensional geometry and stratigraphic record of meandering

This presentation explores the dynamics of meandering systems in both fluvial and submarine environments, focusing on the predictability of channel migration and the resulting stratigraphic heterogeneities.
