Characterization of the banks of the fluvial part of the St. Lawrence and analysis of the evolution of hydro-climatic factors influencing erosion and flooding hazards

As part of measure 2.6 of the 2013-2020 Climate Change Action Plan, the MELCC financed two projects specific to the St. Lawrence river section and aimed at supporting municipalities facing the risks of erosion and flooding. The team of the Laboratoire de Géomorphology Terre-Mer du Département de Géomorphology de l'Université Laval has set up an essential geospatial information base for assessing the risks associated with the erosion of the banks of the banks of the St. Lawrence river section. The user will be able to find there (i) the mapping of the classification of the shore (types of banks and their artificialization), (ii) the degradation conditions of artificial structures and (iii) the state of erosion of natural or artificial segments. The sectors most vulnerable to erosion have also been mapped and documented with image quality sheets. These sheets present the characteristics of the shoreline and the main natural (currents, ice, etc.) and human geomorphological processes (currents, ice, etc.) associated with bank erosion for these nerve sectors, in order to better represent local dynamics. The geospatial data associated with shoreline mapping, the quality sheets and the…
