Méthodes de spatialisation de réseaux arborescents et orientés par simulations conditionnelles : application aux réseaux de fossés de paysages viticoles

Abstract : Artificial drainage networks impact strongly cultivated landscapes hydrology. The improvement of hydrological tools and methods that aim to assess the hydrological impacts of those artificial networks is dependent to our capabilities to map these networks, i.e. its directed tree architectures and its local characteristics, highly variable in space. This thesis develops stochastic methods that aim to map drainage networks. We first developed a geostatistical framework to simulate variabilities along directed trees. A method that simulate network architecture by linking network segments detected with LiDAR is secondly proposed. These developments simulate hydrographic networks in cultivated landscapes that are both conditioned by spatial sampling on networks and by the structure of the space that supports these simulations. These hydrographic networks conditional simulation methods are useful to complete scarce data and to asses hydrological model sensitivity to networks spatial structures.
