Former studies about coastal upwelling along the Western Iberian Peninsula (WIP) using historical data indicated contradictory results, showing either its strengthening or reduction, while previous studies using Global Climate Models (GCMs) indicated that global warming is likely to intensify this phenomenon although predicting different rates and not justifying the patterns found. Taking advantage of the recent high spatial resolution Regional Climate Models (RCMs) projections from EURO-CORDEX project (Representative Concentration Pathway, RCP 8.5), detailed higher accuracy estimations of the spatio-temporal trends of Upwelling Index (UI) along the WIP coast were performed in this study, integrating the coastal mesoscale effects within the framework of climate change. Additionally, this research brings new insights about the origin of the WIP coastal upwelling intensification over the next century. These new projections clarified the upwelling strengthening rates predicted along the coast of the WIP from 2006 to 2099 revealing more prominent changes in the northern limit of the region (25-30m(3)s(-1)km(-1) per decade between 41.5 and 42.5°N). Trends observed at high latitudes of the region were found to be induced by the displacement of the Azores High, which will intensify (0.03hPa per decade) and drift northeastward (10km per decade) during the 21st century.

A unified discretization of rigid solids and fluids is introduced, allowing for resolved simulations of fluid–solid phases within a meshless framework. The numerical solution, attained by Smoothed Particle Hydrodynamics (SPH) and a variation of Discrete Element Method (DEM), the Distributed Contact Discrete Element Method (DCDEM) discretization, is achieved by directly considering solid–solid and solid–fluid interactions. The novelty of the work is centred on the generalization of the coupling of the DEM and SPH methodologies for resolved simulations, allowing for state-of-the-art contact mechanics theories to be used in arbitrary geometries, while fluid to solid and vice versa momentum transfers are accurately described. The methods are introduced, analysed and discussed. Initial validations on the DCDEM and the fluid coupling are presented, drawing from test cases in the literature. An experimental campaign serves as a validation point for complex, large scale solid–fluid flows, where a set of blocks in several configurations is subjected to a dam-break wave. Blocks are tracked and positions are then compared between experimental data and the numerical solutions. A Particle Image Velocimetry (PIV) technique allows for the quantification of the flow field and direct comparison with numerical data. The results show that the model is accurate and is capable of treating highly complex interactions, such as transport of debris or hydrodynamic actions on structures, if relevant scales are reproduced.

Highlights•Describes a SPH methodology to deal with transport of radionuclides•Can be applied to simulate the decay chain transport of radionuclides•The method is demonstrated for environmental engineering problems•The formulation is based on the open-source parallel code DualSPHysics.•The accuracy of the present SPH 2D and 3D model has been shown. AbstractA smoothed particle hydrodynamics (SPH) model is presented for simulating the decay chain transport of radionuclides in confined aqueous solutions. The SPH formulation is based on the open-source parallel code DualSPHysics extended to solve the advective-diffusion equation for the evolution of the concentration field coupled to the fluid-dynamic equations, including the effects of radioactive decay of the tracer contaminants. The performance of the method is demonstrated for environmental engineering problems dealing with the transport of contaminants in still and flowing water. The results from a series of benchmark test calculations are described in two- and three-space dimensions, where the advection, diffusion, and radioactive decay modes are tested separately and in combined form. The accuracy of the present SPH transport model is shown by direct comparison with the analytical solutions and results from other SPH approaches. For a given problem, convergence of the SPH solution is seen to increase with decreasing particle size and spacing.

Highlights•Interaction between two coastal river plumes demonstrated by numerical modeling.•Important role of Douro inflow on the northward WIBP current stabilization.•Douro plume impacts Minho plume modifying the freshwater fate.•Upstream plume prevents offshore freshwater exportation by small-scale eddies.•Reduced stratification induced by Douro plume enhances water exchange with Rias Baixas. AbstractThe Douro and Minho Rivers are the most important freshwater contributors on the northwestern coast of the Iberian Peninsula. Although their interaction is poorly understood, it is well known that they generate the Western Iberian Buoyant Plume (WIBP). This study aims to research the interaction of the Douro and Minho estuarine plumes under winter conditions, with a focus on the changes induced in normal WIBP patterns. Additionally, it will assess the impact of these changes on the Rias Baixas dynamics. An integrated analysis of the dispersion of these plumes was performed through hydrodynamic and Lagrangian numerical simulations of representative winter conditions for January and February 2010. Several simulations were carried out to study the interaction between plumes and their direct and indirect influence on coastal circulation.Under downwelling-favorable winds, the interaction between the Douro and Minho plumes is clear. Both plumes tend to be confined against the coast, as Ekman transport generates a buoyant coastal band with high surface currents. Douro estuary inflow reaches the Minho River coastal region and interacts with the Minho plume to modify freshwater fate. The Douro estuarine plume plays an important role in stabilizing WIBP, by preventing small-scale eddy generation and, consequently, the offshore freshwater transport. In addition, the Douro River has been shown to have a crucial influence on plume stratification, by enhancing the water exchange with the Rias de Vigo and Pontevedra. Interaction between the Douro and Minho plumes is unlikely during upwelling events. Finally, despite the Douro River having the higher discharge, it has a small direct influence on the Rias Baixas.
