Abstract

[en] Water temperature is a key parameter in aquatic ecosystems controlling chemical and
physical processes. These essential ecosystems have been threatened for many years by
increasing anthropogenic pressure and worrying climate change. Existing data of water
temperature are generally derived from thermometers which, although accurate, have very
low spatial resolution. Fortunately, the development of new technologies has made it possible
to apply new methods of temperature measurement such as remote sensing by infrared
thermography. The high spatial resolution offered by this technology allows to study thermal
heterogeneities and consequently to learn more about the functioning of watercourses
by determining factors influencing its temperature. Therefore, the objectives of this work
consisted rstly in using a method of remote sensing by infrared thermography to highlight
the spatial thermal variability of water in the environment of a river. Secondly, to
compare the results from two different thermal cameras, and nally to compare the measurements from infrared thermography with a classical in situ temperature measurement
by thermometers.
