    Beach inundation and morphological changes during storms using video monitoring techniques 

    Sancho García, Amanda (Date of defense: 2012-11-16)

    The predictability of beach inundation is mainly related to wave runup and most of the formulations that have been developed focus on the hydrodynamics, disregarding the morphological changes caused during storms. For these ...

    Estudio numérico-experimental de la dinámica de la zona cercana a la costa 

    Mosso Aranda, Octavio Cesar (Date of defense: 2004-07-07)

    En la actualidad, las decisiones en la ingeniería de costas y la gestión costera se apoyan, cada vez más, en los modelos numéricos predictivos de los procesos costeros, que por otra parte, se basan en modelos conceptuales ...

    Exploiting the multiscale synergy among ocean variables : application to the improvement of remote sensing salinity maps 

    Umbert Ceresuela, Marta (Date of defense: 2015-10-23)

    Les imatges de teledetecció de la superfície oceànica proporcionen una vista sinòptica de la complexa geometria de la circulació oceànica, dominada per la variabilitat de mesoescala. Estructures com filaments i vòrtex són ...

    Hydrodynamic response of a shallow and microtidal estuary : Alfacs Bay. From high to low frequency processes 

    Cerralbo Peñarroya, Pablo (Date of defense: 2015-07-24)

    Using both observations and modelling tools, it is investigated the main hydrodynamic response mechanisms of a microtidal and shallow bay in the Mediterranean Sea: Alfacs Bay. Main objectives are considered using differenttim ...

    Improving wave forecasting in variable wind conditions : the effect of resolution and growth rate for the catalan coast 

    Alomar Domínguez, Marta (Date of defense: 2012-12-03)

    The main objective of this study is to improve wind wave forecasting in the NW Mediterranean Sea while focusing on the characteristic sharp gradients of the wind and wave conditions. This work was motivated by the limited ...

    Incisión de ríos por extracción aluvial y retirada de presas. Estudio matemático y experimental. 

    Ferrer Boix, Carles (Date of defense: 2011-03-23)

    This Thesis deals with incision (bed degradation or general bed scouring) in rivers. More specifically it deals with the incision caused by gravel mining and by dam removal. The main goal of the research is to know ...

    Influència de les comunitats bentòniques sobre el sediment al litoral del delta de l'ebre 

    Soriano Zaragoza, Sergi (Date of defense: 2004-12-06)

    La interacció dels organismes bentònics amb el sediment es relaciona, bàsicament, amb els processos de bioturbació i els de rugositat de fons. Els principals factors implicats en la mobilització de sediment a la plataforma ...

    On the circulation of the North Atlantic shadow zone 

    Peña Izquierdo, Jesús (Date of defense: 2015-02-20)

    Regions isolated from the wind-driven circulation are found in the eastern margins of the world's tropical oceans. The weak and stagnant circulation of these so-called “shadow zones”, in combination with the intense ...

    Sediment dynamics and associated heavy metals in small river-and wave-dominated inner shelf (Barcelona city, Nw Mediterranean) 

    López Fernández, Laura (Date of defense: 2013-10-24)

    Wave storms and river inputs have been found to be the dominant forcing mechanism of sediment transport in continental shelves dominated by medium to large rivers around the world (e.g. Drake and Cacchione, 1985; Sherwood ...
