Polygons representing areas vulnerable to heavy rains, heat waves, destructive storms, droughts, and floods. Vulnerability corresponds to the propensity or predisposition of a system (community, infrastructure and natural environment) to suffer damage caused by the manifestation of a climatic hazard. It varies according to the nature, extent and pace of the evolution of the event as well as the variation in the climate to which the system is exposed, the sensitivity of this system and its capacity to adapt. The [Climate Plan 2020-2030] (https://portail-m4s.s3.montreal.ca/pdf/Plan_climat%2020-16-16-VF4_VDM.pdf) aims, among other things, to improve urban planning and regulatory tools. Montréal has thus committed to updating the climate change vulnerability analysis, including the heat island map, carried out as part of the 2015-2020 Agglomération de Montréal Climate Change Adaptation Plan and to integrating it into the next urban and mobility plan. In addition, in order to take stock of the evolution of the Climate Plan, the City of Montreal annually publishes an [accountability report] (https://montreal.ca/articles/plan-climat-montreal-objectif-carboneutralite-dici-2050-7613) of its 46 actions as well as its eight indicators, including the state of the various climate hazards illustrated by vulnerability maps. The data can also be consulted on the [interactive map of vulnerabilities to climate hazards in the Montreal agglomeration] (https://bter.maps.arcgis.com/apps/webappviewer/index.html?id=157cde446d8942d7b4367e2159942e05).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The Multi-Risk Vigilance Card is a product developed by the Ministry of Public Security (MSP) that brings together warnings and reports on phenomena of natural origin that may have consequences on the safety of citizens, goods and services to the population. It is updated continuously automatically. It allows for continuous monitoring of the province's territory in relation to dangerous natural phenomena. Environment and Climate Change Canada weather warnings for blizzard, fog, freezing rain, rain, fog, freezing rain, rain, snow, hail, hurricanes, tropical storms, winter storms, severe storms, tornadoes, tornadoes, storm winds, storm winds, strong winds, strong winds, strong winds, hurricane force winds, high winds, hurricane-force winds, heat waves, and all weather events whose severity* is greater than or equal to moderate; This data comes from the company's National Alert Aggregation and Dissemination System (ADNA) Pelmorex private. The information conveyed in the alerts complies with the standards of the Common Alert Protocol (PAC).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

As part of measure 2.6 of the 2013-2020 Action Plan on Climate Change, and in the wake of the project “[Characterization of the banks of the fluvial part of the St. Lawrence and analysis of the evolution of hydro-climatic factors influencing the hazards of erosion and flooding] (https://www.donneesquebec.ca/recherche/dataset/caracterisation-des-berges-et-analyse-de-l-evolution-des-facteurs-hydro-climatiques)” ()”, the MELCCFP mandated the team of the **Laboratoire de Géomorphology Terre-Mer du Département de Géomorphology de l'Université Laval ** in order to conduct a study on the mobility issues of banks in the fluvial section of the St. Lawrence. The selection of the six issues, spread over ten sites of interest, was based on the previous shoreline characterization project, which made it possible to locate significant problems related to shoreline mobility. The six issues addressed correspond to: 1. The archipelagos of the fluvial St. Lawrence and the seaway (sites of Île Marie, Île de Grace and Île des Barques) 2. Land use planning and delta formation in Lake Saint-Pierre (Yamachiche Point site) 3. The degradation of the sloping walls between Sainte-Marthe-du-Cap and Champlain (Pointe-au-Vent and Champlain sites) 4. The rapid dynamics of high soft cliffs (Cap Lévrard site) 5. The effects of docks on sedimentary transit in the fluvial estuary (Portneuf and Pointe-Platon sites) 6. The management of urban beaches in Quebec (Plage-Jacques-Cartier site, Anse-Tibbits site and Beauport Bay Beach) This new study has thus made it possible to provide scientific knowledge adapted to the specificities of this densely populated sector of the river, in order to (1) better understand the hydrogeomorphological trajectory of this major river system, and (2) to guide management practices towards better respect of its mobility space and the integrity of its ecosystems. The development of a multi-scale monitoring approach, combining geomorphological and geohistorical components, has proven to be very effective in documenting the implications of the highly artificial nature of the fluvial St. Lawrence and in better defining the influence of natural processes. The project was made possible thanks to the creation of a vast geospatial database, collected and processed by the research team. In an approach of sharing and dissemination, the team makes available all the deliverables and geospatial data* produced during this study, in particular: A complete report detailing the context of the study, the methodology, the results in the form of six abundantly illustrated Mobility-Trajectory sheets, as well as a summary accompanied by a discussion on the impacts of land use planning along the fluvial St. Self-supported version of the six Mobility-Trajectory portrait sheets. Geospatial data associated with the historical mapping of coastline features (CTs) and their migration rates, as well as products derived from drone imagery, such as numerical surface models (MNS) and orthomosaics. *Higher spatial and temporal resolution data are available upon request.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
