IceFlow

Metadata

Also known as
Model type	Single
Model part of larger framework

Incorporated models or components:

Spatial dimensions	2D
Spatial extent	Landscape-Scale, Regional-Scale, Watershed-Scale
Model domain	Terrestrial, Hydrology, Cryosphere
One-line model description	2D semi-implicit shallow ice approximation glacier model
Extended model description	IceFlow simulates ice dynamics by solving equations for internal deformation and simplified basal sliding in glacial systems. It is designed for computational efficiency by using the shallow ice approximation for driving stress, which it solves alongside basal sliding using a semi-implicit direct solver. IceFlow is integrated with GRASS GIS to automatically generate input grids from a geospatial database.

Introduction

History

IceFlow was originally written in Matlab by William Colgan. In 2014, Andrew Wickert translated it into Python and added an automated interface to retrieve input data from a GRASS GIS location.
