Les conditions géographiques et l’organisation spatiale du front de la Grande Guerre – Application à l’évaluation environnementales post-conflit en Champagne-Ardenne (France).

Abstract : The purpose of the thesis, carried out under the IMPACT14-18 program (2015-2018), is to map and measure the environmental impact of the First World War in Champagne-Ardenne. The project offers a new approach of the Great War by a spatial analysis of the defense networks on the 115 km of front (13 000 km of trenches and communication trenches) achieved under GIS from the 1/20 000 of 1918 trenches maps of the “Groupes de Canevas de Tirs des Armées”. The treatment of spatial database not only helps us to determine the potential of "Polemo Landscapes" of the Great War but also to understand the military and geographical factors (geomorphology, geology, hydrography) structuring the networks. Associated morphologies (trenches, communications trenches, mine craters, shells craters), fully leveled in the field but highlighted by the archaeological approach, are studied sectorally under the forest thanks to the airborne Lidar, in order to define their conservation rates, according to the silvicultural practices. The operational application of the results fits the environmental assessment and the post-conflict territorial issues of the Great War ("cavities" hazard, bombturbation, soil and groundwater contamination) but also reveals a potential for heritage enhancement.
