Digsure method: Decision support indicators and GIS tool for levees management
Méthode Digsure : indicateurs d'aide à la décision et outil SIG pour la gestion des digues
Abstract
France and more generally the world undergo frequent episodes of devastating floods. Human and material damages are multiplied during the break of a protection structure. Regrettably, these structures are long alignment, most of the time badly maintained, showing signs of weaknesses on numerous occasions. Levees management raises then considerable problems to the decision makers asked to guarantee a maximal security to the populations for a rational and acceptable management cost. Ambitions of Digsure project is to propose to manager scientific methods and technical tools for levees management. These tools will be able of estimating levee performance all along alignment, vulnerability of leveed areas, and to provide decision support about manager action.
