The main objective of this work is to study the impact of climate change on the circulation and hydrography of the Ria de Arousa, considering the SSP5-8.5 scenario defined by IPCC. To achieve this goal, the Delft3D hydrodynamic model was implemented three-dimensionally using the results obtained from the CMIP6 MPI-ESM1-2-HR climate model as boundary conditions. Future changes in the hydrodynamic and hydrographic circulation of this coastal system were analysed. The model results were used to assess the impact of climate change on water temperature, salinity, and density patterns of the Ria de Arousa, as well as on stratification, Brunt\u2013V\u00e4is\u00e4l\u00e4 frequency, and residual circulation. During summer, the water temperature is higher at the surface and lower at the bottom, likely due to the intrusion of water from the Eastern North Atlantic Central Water (ENAWC). In the future, this pattern will continue, albeit with higher temperatures, as the water temperature is expected to increase by around 2.2 \u00b0C by 2100. During winter, the water temperature at the bottom is warmer than at the surface, indicating a thermal inversion typical of this season. In the future, the water temperature will also increase, although the increase will be lower compared to summer, with a value of approximately 0.5 \u00b0C. Salinity will decrease in the summer and increase in the winter, especially in the areas closest to the rivers. Density analysis shows vertical homogeneity in the water column during winter and stratification during summer. During winter, the Brunt\u2013V\u00e4is\u00e4l\u00e4 frequency (N) is higher in the region closest to the river\u2019s mouth and lower near the ocean. In the summer, the N value decreases with depth. In the future, the density will increase in winter and decrease in summer, and stratification is expected to decrease. Regarding the residual circulation, it was observed that it will strengthen in the summer and weaken in the winter due to a decrease in freshwater runoff. However, the positive circulation pattern observed in the present will be maintained in the future.<\/jats:p>","DOI":"10.3390\/jmse13061063","type":"journal-article","created":{"date-parts":[[2025,5,28]],"date-time":"2025-05-28T08:12:47Z","timestamp":1748419967000},"page":"1063","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Impact of Climate Change on the Hydrodynamics of the Ria de Arousa (NW Spain)"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-8321-9218","authenticated-orcid":false,"given":"Clara","family":"Ribeiro","sequence":"first","affiliation":[{"name":"Physics Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2575-3263","authenticated-orcid":false,"given":"Magda C.","family":"Sousa","sequence":"additional","affiliation":[{"name":"Centre for Environmental and Marine Studies, Physics Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2291-5549","authenticated-orcid":false,"given":"Humberto","family":"Pereira","sequence":"additional","affiliation":[{"name":"Centre for Environmental and Marine Studies, Physics Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5824-1542","authenticated-orcid":false,"given":"Am\u00e9rico","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Centre for Environmental and Marine Studies, Physics Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3837-1742","authenticated-orcid":false,"given":"Ines","family":"Alvarez","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n Mari\u00f1a (CIM), Environmental Physics Laboratory, Universidad de Vigo, Edificio Campus da Auga, 32004 Ourense, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7613-6241","authenticated-orcid":false,"given":"Jo\u00e3o M.","family":"Dias","sequence":"additional","affiliation":[{"name":"Centre for Environmental and Marine Studies, Physics Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"136117","DOI":"10.1016\/j.scitotenv.2019.136117","article-title":"How can ocean warming at the NW Iberian Peninsula affect mussel aquaculture?","volume":"709","author":"Des","year":"2020","journal-title":"Sci.
