Stimulation from simulation? A teaching model of hillslope hydrology for use on microcomputers

Abstract

The design and use of a simple computer model which simulates aspects of hillslope hydrology is described in a teaching context. The model shows how a relatively complex environmental system can be constructed on the basis of simple but realistic theory, thus allowing the student to simulate the hydrological response of real hillslopes. Initial runs allow the student to explore how the system operates; at this stage the model can serve as an important adjunct to lectures and field studies. At a more advanced level, the model can be used as a means of extending investigations well beyond the possibilities of controlled field experimentation; a large number of simulations can be run in a short time and the results used to define the role of particular variables.
