OBJECTIVE

To present the basic concepts and methods of geostatistics in cartography of pollutants. The subject matter ranges from variograms to different types of kriging techniques and co-kriging when several variables are correlated.

A particular attention is paid to the integration of these methods for the study, the polluted sites remediation and follow up: accounting for the historical data, sampling optimization, cartography of in situ pollution and use of auxiliary variables.

KEY FEATURES

Half of the course is dedicated to practical computer exercises, using Isatis in order to reinforce the previously presented theoretical notions.

WHO SHOULD ATTEND

The course is designed for practitioners confronted to the study of polluted sites and who wish a practical introduction to geostatistical methods. No prior knowledge of geostatistics is required. However a basic understanding of statistics is recommended.

COURSE CONTENT

Introduction: what is geostatistics? The advantages of using geostatistics over existing methods.
The foundation stone of geostatistics: quantifying the spatial behaviour via the variogram. Calculating, modelling and interpreting the directional variograms.
Interpolating between the data: the theory and practice of kriging.
The fundamental concept of support: differences between sampling support, estimation and depollution support.
Multivariate geostatistics and cokriging. Incorporating the correlation between several variables improves the final estimate.
Using non-stationary geostatistics to respect the trend present in the data.
The limitations of kriging and the introduction to risk analysis: calculation of the probability ot overcome a pollution threshold.
