    Development and interactions of surfzone morphological patterns 

    de Swart, Rinse Leendert (Date of defense: 2022-07-19)

    A variety of morphodynamic patterns are typically present in the nearshore zone of sandy beaches that develop due to the interactions between waves, currents and the morphology. The most common are one or several nearshore ...

    Dynamics and physical processes involving extreme temperatures in the Iberian Peninsula and Iraq 

    Mohammed, Ali Jasim (Date of defense: 2018-10-03)

    The occurrence of heat waves and cold spells has received special attention in recent years due to their impact on human health, ecosystems and economy. In the context of climate change, there is evidence that extreme ...

    Dynamics of cyclones and precipitation over the Middle East 

    Al-Nassar, Ali Raheem Tuaimah (Date of defense: 2018-09-25)

    Precipitation is one of the most important, and also difficult to predict, elements of climate. This difficulty is associated with the transport of moisture through weather fronts that change their pathway, shape and ...

    Hilbert analysis of air temperature dynamics 

    Zappalà, Dario (Date of defense: 2019-04-04)

    The dynamics of the climate system plays a crucial role in the sustainability of life on Earth, and this motivates research to understand and characterise our climate and predict its evolution. In this thesis we focus on ...

    Models of stellar winds from X-ray bursts 

    Herrera, Yago (Date of defense: 2021-12-15)

    The study of stellar winds (SW) in the context of X-ray bursts (XRB) performed in this thesis has two main motivating issues. The first is whether or not the heavy elements produced from nucleosynthesis in XRBs can escape ...

    On cross-shore beach profile morphodynamics 

    Fernàndez Mora, Mª Àngels (Date of defense: 2015-12-17)

    The nearshore zone is plenty of 3D morphodynamic patterns resulting from the interaction of waves, currents and sediments. The dynamics of formation and evolution of these patterns is at present a controversial point in ...
