Modeling Glacial erosion using ice velocity and rock strength in Coastal Alaska
Will Kochtitzky and Ian Nesbitt
This project uses a very basic, very generalized, "fudge factored" rock cohesion classification (shown below) to estimate erosion in coastal Alaska at present and throughout the last 110,000 years. Modeled velocity and ice extent data provided graciously by Annie Boucher.
Seen here is a an estimate of glacial erosion based on the velocity-driven erosion model of [and Raymond (1994)] at all time steps since 115.5 thousand years before present.
Seen here is the same model applied to a modern velocity dataset which uses a finer resolution.
