dc.description.abstractDeltas are low-lying plains that form where the river flows into the sea. They are “hotspots” of climate change since they are sensitive to any variation in sea level and climate change. In this sense, the Brazilian deltas have received little attention in the international literature in relation to ongoing climate changes. The projections of sea level rise by the IPCC of up to 1.01 m by the end of this century put the existence of deltas at risk since a rise in sea level of this magnitude will be able to flood about 40% of Jequitinhonha’s plain area. Additionally, changes in precipitation patterns over the drainage basin are also capable of drastically changing the shoreline behavior. There has been a reduction of approximately 15% in precipitation over the Jequitinhonha watershed since 2006 and the Jequitinhonha river has had increasingly reduced flows, which has triggered severe erosion of the coastline, mainly at the mouth of this river. Considering the forecasts of the National Institute for Space Research (INPE) that indicate a 48% reduction in precipitation in this basin by the end of this century, the stability of the coastline of the deltaic plain will be drastically affected. The insights gained from the present study shed light on the understanding of the vulnerability of wave-dominated deltas to climate change.pt_BR

dc.description.resumoDeltas são regiões mais baixas do relevo que se formam onde o rio desemboca no mar. São “hotspots” das mudanças climáticas uma vez que são sensíveis a qualquer variação no nível do mar e alterações climáticas. Nesse sentido, os deltas brasileiros têm recebido pouca atenção na literatura internacional em relação às mudanças climáticas em curso. As projeções de aumento do nível do mar pelo IPCC em até 1,1 m até o final deste século coloca em risco a existência dos deltas uma vez que um aumento do nível do mar dessa magnitude será capaz de inundar cerca de 40 % da área da planície do Jequitinhonha. Adicionalmente, alterações nos padrões de precipitação sobre a bacia de drenagem também são capazes de alterar drasticamente o comportamento da linha de costa. Verificou-se uma redução de aproximadamente 15% da precipitação sob a bacia hidrográfica do Jequitinhonha desde 2006 e o rio Jequitinhonha tem apresentado vazões cada vez mais reduzidas, que desencadeou erosão severa da linha de costa principalmente na desembocadura deste rio. Considerando as previsões do Instituto Nacional de Pesquisas Espaciais (INPE) que indicam redução de 48% na precipitação desta bacia até o final deste século, a estabilidade da linha de costa da planície deltaica será drasticamente afetada. Os insights adquiridos com o presente estudo trazem à luz o entendimento sobre a vulnerabilidade de deltas dominados por ondas frente às mudanças climáticas.pt_BR
