A model is a representation of the essential aspects of a system presented in a usable form.
Models are often based around fundamental physical equations that incorporate the best-known understanding of process response. Models in the natural sciences often also include empirical (ie: data-derived) relationships or simplified ‘physically-based’ relationships. They also generally draw on knowledge from multiple disciplines.
For example, a glacier model will include information from fluid mechanics (Navier-Stokes equations), laboratory experiments (Glen’s flow law) and the local geography (sub-ice bedrock profile, climate).
We are currently undertaking research with the following models:
