The aim of the module is to show how environmental problems may be solved from the initial problem, to mathematical formulation and numerical solution. Problems will be described conceptually, then defined mathematically, then solved numerically via computer programming. The module consists of lectures on numerical methods and computing practicals (Matlab): the practicals being designed to illustrate the solution of problems using the methods covered in lectures. The module will guide students through the solution of a model of an environmental process of their own choosing. The problem will be discussed and placed into context through an essay, and then solved and written up in a project report. The skills developed in this module are highly valued by prospective employers of students wishing to carry on into further studies or in professional employment.
