This thesis investigates numerical methods that approximate the solution of compressible flow equations. The first part of the thesis is committed to studying the Variational Multi-Scale (VMS) finite element approximation ...

Marine mammals face numerous anthropogenic threats, including fisheries interactions, ocean noise, ship strikes, and marine debris. Monitoring the negative impact on marine mammals through the assessment of population ...

The damage assessment of structures under seismic actions, must seek the implementation of new theories, tools and procedures that reduce the uncertainty associated to the expected structural response of a building. This ...

Coupled processes between the soil and the atmosphere control soil water evaporation in its first stage, which leads to soil shrinkage and cracking by drying. However, soil-atmosphere interaction has received little attention ...

Collision between adjoining buildings is relevant, since the huge impact forces significantly modify the buildings dynamic behaviour. The separation required by the regulations avoids pounding; however, even in recent ...

The water currents and the wave field at the Catalan coast (in the Northwestern Mediterranean Sea) are investigated. However, the main research is focused at the northern margin of the Ebro Shelf, where there is a relatively ...

The conceptualisation of a groundwater system involves continuous monitoring and evaluation of a large number of parameters (e.g., hydraulic parameters). Regarding hydraulic properties of the aquifers, their quantification ...

The construction and conservation of road networks represent a major part of public expenditure. For instance, the EU-28 countries annually spend approximately EUR 20.000 million on roadway preservation. These figures ...

High performance steel fibre reinforced cementitious composites (HPSFRCCs) show enhanced structural performance and durability. The improved properties favour its use in agressive conditions (such as marine environment) ...

Nowadays, thanks to the increase of computers capability to solve huge and complex problems, and also thanks to the endless effort of the geotechnical community to define better and more sophisticated constitutive models, ...
