Glacier Modeling

Project description

We are using a newly developed debris-covered glacier model to determine the effect of debris cover on glacier length. The model allows for fully transient advection of debris through and on top of the glacier. We are currently exploring the basic feedbacks between debris input location, erosion rate, mass balance parameterization, and glacier length.

Objectives

1) Determine how debris-cover effects glacier length using numerical models 2) determine how debris input location on a glacier effects glacier length

Time-line

Start: Oct 2014 - Dec 2015

Models in use

We are using 1 and 2D Matlab-based numerical glacier models. The models are used in both idealized and geographical settings with a variety of parameterizations for glacier mass balance. We are primarily using a 2D debris-covered glacier code to determine the importance of debris-cover on glacier length. Beach allows us to explore a wide parameter range efficiently and is therefore imperative for the success of this project. We will also be using gc2D.

Results

Results are in preliminary stages, though we include some model output for your perusal.
