Coastlines along the St. Lawrence Estuary and Gulf, Eastern Canada, are under increasing risk of flooding due to sea level rise ice shrinking. Efficient validated regional‐scale coastal flood mapping approaches that include storm surges waves hence required better prepare for increased hazard. This paper compares validates two different methods: numerical simulations using XBeach bathtub based on total water levels, forced with multihazard scenarios compound wave events. is hydrodynamic...
Bernatchez, P., and Fraser, C., 2012. Evolution of coastal defence structures consequences for beach width trends, Québec, Canada.Over recent decades, amplification erosion, coupled with the expansion built environment in Québec's maritime region, has led to a significant increase structures. On unconsolidated coasts, severe reduction was noted following construction hard engineered when compared beaches no such constructions. Beaches sectors Sept-Îles Percé, where shorelines have been...
On 6 December 2010, an extra-tropical storm reached Atlantic Canada, causing coastal flooding due to high water levels being driven toward the north shore of Chaleur Bay. The extent was identified in field along coastline at Maria using DGPS. Using assumption that maximum elevation flooded areas represents combination astronomical tide, surge and wave runup, which is by breaking waves on beach, all flood limits were identified. A flood-zone delineation performed GIS LiDAR data. An empirical...
Faced with climate change and the increasing pressure exerted by marine dynamics on coastline (notably coastal erosion submersion), adapting impacted territories has become a major challenge. Several solutions exist to protect communities. In Quebec, numerous beach nourishments have been completed or are currently underway. This type of solution is increasingly being implemented (Hinkel et al., 2013). However, follow-up studies necessary better quantify their impact coast, particularly...
Un bilan des connaissances de la dynamique l’érosion côtière dans l’estuaire et le golfe du Saint-Laurent montre que recul littoral les formations meubles est très important, variant généralement entre 0,5 2 m/an. Les données indiquent une accélération récente phénomène, ce qui va sens tendance mondiale appréhendée contexte changements climatiques. Il semble côtes à marais maritimes soient plus sensibles, certains schorres supérieurs ayant déjà disparu au cours dernière décennie. Cela...
This study presents the development of a geographic information system (GIS) land-use planning tool for coastal areas based on calculated exposure to erosion buildings and infrastructure. Responding needs planners, who are involved in project from beginning, this facilitates identification adaptation solutions sensitivity erosion. All buildings, roads, railways, aqueducts, sewer systems, hiking trails bicycle routes were mapped at high resolution, an value was assigned each seven time...
The Magdalen Islands (Québec, Canada) are a key location for unravelling the glacial and sea‐level history of Maritime Provinces eastern Canada. Although many sedimentary sequences have been described in literature, absolute ages lacking, impeding an accurate interpretation deposits establishment precise chronological framework. This study provides detailed description 21 stratigraphical located throughout archipelago, as well first comprehensive luminescence chronology from Last Glacial...
ABSTRACT Proxy records of late Holocene relative sea‐level changes are important for our understanding mechanisms that drive contemporary trends. In the Gulf Saint Lawrence (eastern Canada), Magdalen Islands currently experience higher than global average rates rise. This article presents original reconstruction data from over past few millennia collected a variety coastal deposits and proxy including salt‐marsh foraminifera, testate amoebae plant macrofossils. Reconstructed trends between...
The St. Lawrence is a vast and complex socio-ecological system providing wealth of services sustaining numerous economic sectors. These ecosystems are subject to significant human pressures that overlap potentially interact with climate driven environmental changes. Our objective in this paper systematically characterize the distribution intensity drivers System. To do so, we launch eDrivers, an open knowledge platform gathering experts committed structuring, standardizing sharing on support...
A quantification of coastal erosion processes on a clay cliff in cold temperate region was conducted. This study based network markers that were measured monthly basis from 1998 to 2003. During period, the average retreat rate 1.5 m/y. Our results demonstrate weathering is more significant factor than hydrodynamic fine sediment shorelines. statement opposes conventional understanding. In fact, 65% annual took place through winter season when waves could not reach foot because an ice foot....
The distribution of decisional power and ability local communities to participate in natural hazard risk governance (NHRG) are critical success factors for sustainable development. This article assesses the evolution participation at level NHRG using bibliometric international discourse analysis. results show that participation-related concepts underrepresented NHRG, compared environmental resource management community & livelihood development fields research. implies existence...
Intertidal vegetation provides important ecological functions, such as food and shelter for wildlife services with increased coastline protection from erosion. In cold temperate subarctic environments, the short growing season has a significant impact on phenological response of different types, which must be considered their mapping using satellite remote sensing technologies. This study focuses effect phenology in intertidal ecosystems outputs. The studied sites were dominated by eelgrass...
