Free webinar - Groundwater Modelling: An Introduction

Dr Michael Teubner will be conducting a free webinar on an introduction to groundwater modelling on the 10th of December 2014. Michael has over 40 years of experience in modelling water systems as an environmental consultant in the US and as an academic researcher and lecturer at universities in Australia.

This webinar is a brief introduction to a 4-day intensive course that will be run by the National Centre for Groundwater Research and Training in late February, 2015. Details of this course can be obtained from

By definition, groundwater cannot be seen and, in general, its flow cannot be measured. An understanding of groundwater and its movement is generally obtained by collecting water level data in the field and making interpretations and extrapolations with these data. Groundwater modelling is an integral part in understanding groundwater conditions and how they have changed in the past and may be predicted to change into the future.

This webinar will discuss the bases for groundwater flow modelling: basic hydrogeological considerations, together with the two laws that help define and provide an understanding of groundwater flow: Darcy’s Law and mass conservation. These two laws lead to the groundwater flow equation, which is the basis of groundwater flow modelling. This equation can be solved exactly for very simplified aquifer systems, but for more complex and realistic conditions, the equations must be solved using numerical techniques. The most widely used numerical modelling code is MODFLOW. This code will be discussed briefly in the webinar as a part of the overall process of groundwater modelling, showing how a model is conceptualized from existing data and developed using available techniques and experience. The webinar will look at each of the steps within the process and consider the limitations and pitfalls associated with each step. Finally, the webinar will provide a quick look at management and regulatory guidance necessary for the acceptable and supportive use of groundwater modelling as a formative management tool.
