Innovative modelling and visualization methods in optimizing is situ remediation of contamination source: way of working, opportunities and risks

IoT is also influencing the contaminated land world, resulting in a lot of tools that give us much more detail on the status of the soil and groundwater (time related data, space related data); future focus will be on sensors for measuring concentrations in soil and groundwater. This increase in amount of data will oblige us to work much more with geostatistical tools and later on with several types of visualization tools. In this presentation we will focus on: - The IoT evolutions - Current data acquisition tools: use of tablets in the field, with automised links to eg laboratories - Manage the data - Analyse the data, including software like PowerBI - Reporting of data - Visualization tools, including virtual reality and augmented virtual reality tools This will be demonstrated by a step by step explanation of a site investigation (a site with tens of drillings, CPT measurements, MIP measurements and a geophysical investigation), building of the conceptual site model, and presenting several augmented/virtual reality tools. Those tools will be demonstrated on small interfaces (eg mobile phone) as well as on the screen. On the other side the risks for mistakes are also important. The main issues are: - how to deal with uncertainties: the density of data will vary between the different parts of the site, creating less and more reliable parts of the CSM - how to discover mistakes: eg a wrong water level? - how to include expertise?
