We introduce the idea of an introductory modelling course to be taught across the undergraduate curriculum. We suggest objectives for such a course and offer approaches for teaching it in an active learning and group-learning environment. We discuss

SUMMARY Land transformations in the catchments of Lake St Lucia have altered the hydrology of the system and increased management is now needed to counteract these changes. There are several management options available, but prior to implementing the

Rangelands are complex systems with many interacting components. Modelling such systems presents two particular and interrelated problems. Firstly, the processes involved operate on greatly differing time scales: long-term changes in rangelands typic

Rock mechanics models fall into the class of “data-limited problems”; one seldom knows enough about a rock mass to model it unambiguously. Modellers are beginning to realize that data-limited problems require a very different modelling approach f

This paper describes a new approach to the problem of defining geometrically polyhedral rock blocks created by the intersection of planar discontinuous in a rock mass. The approach represents an extension of the combinatorial topology concepts to sol

A model, based on the social and territorial behaviour of lions, is used to simulate localized lion culling operations in a large game park. The results are compared with culling experiments performed in the Central District of the Kruger National Pa

It is often difficult to build conventional dynamic models for an ecological system because the relationships between the abiotic and biotic components of the system are understood only in a rough, qualitative rather than a detailed, quantitative sen

This paper outlines the rock mechanics investigations associated with Project Salt Vault, a feasibility study of radioactive waste disposal in an underground salt formation. Laboratory and large-scale in situ experiments are briefly described, and a

A computer model is used to simulate the compressive strain waves generated in rock from the end detonation of long and short cylindrical explosive charges. The model synthesizes the strain wave by superposing the waves from detonation of a number of
