SummaryThis course deals with developing and programming numerical models to simulate hydrogeological systems. The principles of numerical model development will be explored along with the fundamental processes governing heat and mass transport in the subsurface environment with a specific focus on applications for geothermal systems and reactive transport of hazardous industrial contaminants. Students will develop and program their own numerical model to better understand these concepts, their application and the underlying mathematics.
Course description Numerical models are now vital tools in hydrogeology as many applications require the incorporation of complex geology and numerous interconnected environmental processes. For instance, geothermal energy installations, remediation schemes for sites contaminated with hazardous wastes, as well as groundwater abstractions for drinking, agriculture and industrial usages all require the use of numerical models for successful implementation and to minimize negative environmental impacts. While commercial hydrogeological software packages are now available, an understanding of both their development and the governing processes they describe are required to properly utilize and, if necessary, modify. This course will cover all the steps of model development from conceptualization, through to implementation with programming languages, and finally model validation and calibration. Model development will be taught in the context of heat and mass transport processes in hydrogeological systems, specifically with geothermal systems and reactive transport at sites contaminated with hazardous chemicals. The course will cover fundamental heat and mass transport processes such as conduction and convection, advection and dispersion, reaction kinetics, sorption isotherms, as well as the mathematics required to program these processes using finite difference numerical techniques. During this process, students will learn how to critically assess numerical modelling reports to identify their underlying assumptions, limitations, and sources of inaccuracies.



The course lectures develop the students knowledge base with advancing concepts that are supported by practical programming, numerical modelling, and report writing and critical evaluation. This is aimed at developing technical, interpretation and reporting skills and encourage critical thinking. The concepts developed in the taught programme are reinforced with a project wherein students are given a specific hydrogeological scenario that they must develop, program, and implement their own numerical model to simulate and write a professional modelling report on.
