Resumo:Understanding the impact of sea level rise on coastal areas is crucial as a large percentage of the population live on the coast. This study uses computational tools to examine how two major consequences of sea level rise: salt intrusion and an increase in water volume affect the hydrodynamics and flooding areas of a major estuary in the Iberian Peninsula. A 2D numerical model created with the software MOHID was used to simulate the Guadiana Estuary in different scenarios of sea level rise combined with different freshwater flow rates considering varying tidal amplitudes. An increase in salinity was found in response to an increase in mean sea level in both high and low freshwater flow rates at all areas around the estuary. An increase in flooding areas around the estuary was also positively correlated with an increase in mean sea level. (C) 2020 The Authors. Published by Elsevier B.V.
