Environmental Quality Monitoring

Common core courses

The EU brings together tools for measuring the quality of water, the atmosphere and the sound environment. In connection with environmental management (standards, territorial monitoring) and effluents and clean pollution (treatment of effluents and pollution and modelling of the diffusion of pollution).
The objective is to provide the future engineer with methods and tools for geo-surveillance (in natural and urban environments) and pollution detection, whatever the scale of analysis. These tools will enable him/her to understand/develop the entire environmental monitoring chain, from data acquisition by dedicated sensors to information processing that takes into account the modeling of physical phenomena. The monitoring domains addressed range from chemical air pollution to noise prediction and reduction in urban areas and the state of continental surfaces (vegetation) by imagery.

This course deals with tools for detecting pollution indicators, at local and global scales, with sensors and measurements for the environment and geo-monitoring. It also addresses issues related to environmental noise pollution, in order to achieve improvements in the noise environment (in connection with the notion of a sustainable silent city).

1. Sensors and measurements for the environment. (J. Bittebierre & D. Nuel)
Localized measurements with independent sensors or in networks allow a precise monitoring, in real time, on closed sites or on larger spaces. The focus is on the most commonly used sensors for precision localized measurements, and on components for capturing measurements by imagery (optical sensors, including LIDAR (laser-based optical surveillance radar) and hyperspectral camera (camera that provides for each point of the captured image the composition of its spectrum), chemical sensors and gas sensors).

2. Remote sensing. (R. Marion & A. Roueff)
Remote sensing methods for geo-surveillance and pollution characterization. It is possible to extract relevant information on the state of vegetation, soils and seas from embedded sensors (multispectral, hyperspectral or radar). We will see how remote sensing works and how to implement algorithms for mapping through several application examples.

3. Acoustic pollution. (C. Maury & D. Mazzoni)
The focus will be on acoustic pollution in buildings and outdoors, with particular emphasis on the characterization of the acoustic field and sources, and on the treatment with acoustic screens. Also included is a lecture on acoustic technology for the prevention of CO2 storage risks.
