Pre-conference Workshop and tutorial
Three pre-conference workshops will be arranged on 12th June 2016 2-5pm. Details to be announced.

Title: Numerical modelling of GPR using gprMax
The use of numerical modelling techniques in Ground Penetrating Radar (GPR) research and practice has become much more commonplace over recent years. Numerical modelling can be beneficial for both GPR practitioners – to better understand complex GPR scans and responses for improved and safer data interpretation – and also for GPR researchers to test and develop new ideas for processing, imaging and data interpretation. Numerical modelling is also a valuable educational tool for teaching engineers and scientists about GPR and electromagnetic wave propagation in complex environments.
The workshop will begin with explaining the fundamental concepts of the Finite-Difference Time-Domain (FDTD) method for computational electromagnetics. The FDTD method is the basis of one of the most commonly used numerical modelling frameworks for simulating GPR. The second part of the workshop will focus on gprMax (www.gprmax.com) – open source electromagnetic simulation software for modelling GPR. We will describe how the software operates and demonstrate how to use gprMax to effectively model GPR. A selection of different examples of GPR models will be presented and discussed. Attendees will be given guidance and tips on constructing GPR models and how to avoid common errors and pitfalls. Attendees will have the opportunity to follow along with the examples on their own laptop or on locally provided computers.

Title: GPR imaging of geomorphic, geologic and geoarchaeological landscapes: From data collection to basic processing to radar stratigraphic interpretation
Our goal in this workshop is to demonstrate how GPR can aid in better understanding different sedimentary environments This interactive session will draw from over 25 years of GPR imaging experience in various geomorphic, geologic and geoarchaeological settings worldwide.
We will start with an overview of GPR theory that will help in data collection procedures, particularly within the context of earth science applications. Once data is collected, we will step through a processing flow that provides a GPR profile that is ready for radar stratigraphic interpretation. We will then discuss the principles that lead to the concepts of radar stratigraphy. With several hands on exercises participants will be able to develop and apply these concepts to their provided GPR profiles from various geomorphic, geologic and geoarchaeological environments. At the end of this “back to the basics” workshop we will pull the workshop principles together so that one can apply these concepts to their own field projects.
