Managing water resources and the environment requires the integration of global changes, including climate change. Our understanding of water resources is often based on hydrological models. With these models, we can estimate the water balance of a study area and use these models to understand pollutant transport for environmental protection. Until recently, hydrological models only included water flow processes. However, climate change is manifesting itself in increasing temperatures in the atmosphere.

In this seminar, the potential and limits of electric and electromagnetic method for geomaterials characterization will be presented. The first part of the seminar will be focused on the technical aspects of these measurements with a special focus on the high frequency range (above 1 MHz). The different approach to model the measured electrical properties will also be introduced. The second part of the seminar will consist of a series of example of different type of geomaterials dielectric characterization: rocks and cementitious materials.

Nowadays, monitoring the impact of human activities on the environment is a major challenge as many pollutants can be found in the different ecosystems. It is therefore important to understand their past and present evolution to predict future consequences. We are interested here in the impacts of the nuclear industry on rivers that started in the middle of the 20th century.
