Resumo: | This work, realized in the laboratories of the Geologic and Hydrological Studies and Researches Center of the Faculty of Science of Montpellier benefited from the financial support of the CNEXO (training grant) and took place during a part of the third year of Engineering school (ENGEES of Strasbourg). The realized work exploited four thermal airborne exploratory missions to establish the criteria of quality and hydrodynamics of waters of the Leucate lagoon by thermal infrared scanning radiometry. The first part of this work handles climatological, geographical, morphological, hydrological, hydro dynamical and geological known parameters. The second part consists of the descriptive analysis by photo-interpretation of the obtained thermal imaging. Finally the third part offers the synthesis as the critical and comparative analysis of the results. Among these we raise that thermal imaging acquired on a littoral ecosystem according to various conditions of wind and tide (although the tide in this region is very weak) is able to contribute to the hydro dynamical description of the waters masses of the lagoon by highlighting several elements such as: the gaps of draining of the lagoon by its graus between the North, the center and the South, the existence of two hydrological basins with different functioning in the north part and the southern one, the existence of submarine springs of Karstic origin within the lagoon and the extension of fresh water in the water body of the lagoon. In conclusion we underline the interests of the infra-red thermal imaging in terms of spatial, temporal, radiometric as diachronic factors
