Spatial patterns of glacial erosion in mountains

We use numerical modeling to explore how the spatial pattern of glacial erosion varies in different climates as a result of different basal thermal structures.

Post-glacial landscape evolution

Code

PISM

The parallel Ice Sheet Model (PISM, www.pism-docs.org) is an open source, finite difference, shallow ice sheet model. PISM uses a hybrid shallow stress balance to model ice flow, and it solves polythermal energy conservation. I implement a subglacial erosion in PISM (see here) to study glacial landscape evolution in mountain ranges.

Landlab

Landlab (landlab.github.io) is a python-based toolkit for modeling earth surface processes. I implement the FlowRouterOverFlat module (see here) that calculates the flow direction across topography with flats.
