A new morphodynamic instability associated with cross-shore transport in the nearshore
(2021-07-16)
Article
Open AccessThe existing theory for shore-transverse rhythmic sand bars relies on morphodynamic instabilities involving the wave-driven longshore current and rip currents. Intriguingly, transverse finger bars are common on coasts with ... -
A new shoreline instability mechanism related to high-angle waves
(2017)
Conference report
Open AccessA new shoreline instability triggered by high-angle waves and leading to sand wave formation is investigated. In contrast with the well-known high angle wave instability, which involves both the surf and shoaling zones and ... -
Análisis numérico de la interacción suelo-atmosfera en un terraplén experimental
(Universitat Politècnica de Catalunya, 2019-09-16)
Master thesis
Open AccessCuando el terreno no puede absorber la cantidad de agua de lluvia durante un episodio pluvioso, se establece un proceso de escorrentía que puede arrastrar volúmenes importantes de suelo. Tanto la comprensión de las condiciones ... -
Análisis numérico del transporte de sedimentos en la Bahía del Fangar
(Universitat Politècnica de Catalunya, 2020-05-08)
Master thesis
Open AccessLa bahía del Fangar presenta un gran interés ambiental, aunque los usos antrópicos de la misma están alterando sus ecosistemas. Uno de los factores afectados es la dinámica sedimentaria en la propia bahía, que durante los ... -
Beach profile evolution towards equilibrium from varying initial morphologies
(2019-11)
Article
Open AccessThe evolution of different initial beach profiles towards the same final beach configuration is investigated based on large-scale experimental data. The same wave condition was performed three times, each time starting ... -
Beach recovery capacity along Catalan Beaches
(Universitat Politècnica de Catalunya, 2016-09)
Bachelor thesis
Open AccessOnshore offshore transport at the surfzone and close to the breaking zone is mainly induced by waves. Wave regimes then controls the capacity to transport sediment from the submerged part of the beach to the upper/emerged ... -
Breaker bar morphodynamics under erosive and accretive wave conditions in large-scale experiments
(2018)
Article
Open AccessDifferences between breaker bar evolution under high energy (erosive) and subsequent mild energy (accretive) wave conditions are studied based on three data sets from large-scale morphodynamic experiments. Under erosive ... -
Co-evolution of coarse grain structuring and bed roughness in response to episodic sediment supply in an experimental aggrading channel
(2020-03)
Article
Open AccessWe use flume experiments to better understand how gravel-bed channels maintain bed surface stability in response to pulses of sediment supply. Bed elevations and surface imagery at high spatial resolutions were used to ... -
Computational modelling of fine sediment relocation within a dam reservoir by means of artificial flood generation in a reservoir cascade
(2019-04)
Article
Open AccessSediment relocation is a process where water turbulence moves deposits from shallower to deeper zones of a lake or reservoir. Additionally, in the context of a reservoir cascade relocation is a one of the possible sediment ... -
Consolidation of gas hydrate-bearing sediments with hydrate dissociation
(EDP Sciences, 2020-11)
Article
Open AccessQuantifying sediment deformation induced by depressurization of gas hydrate reservoirs and hydrate dissociation is crucial for the safe and economic production of natural gas from hydrates, and for understanding hydrate-related ... -
Coupled Forecasts for Beach Decision Making. La Arena Beach case

Desarrollo de un analisis integral para monitoreos ambientales en cuencas andinas
(Universitat Politècnica de Catalunya, 2012-07)
Master thesis
Open AccessEste trabajo se centra en el desarrollo de un análisis integral empleando monitoreos ambientales en las cuencas andinas específicamente en la cuenca del Titicaca y Jequetepeque situada en el departamento de Puno y Cajamarca ... -
Developments in acoustics for studying wave-driven boundary layer flow and sediment dynamics over rippled sand-beds
(2018-08)
Article
Open AccessThe processes of sediment entrainment, transport, and deposition over bedforms are highly dynamic and temporally and spatially variable. Obtaining measurements to understand these processes has led to ongoing developments ... -

Bachelor thesis
Open AccessAquest TFG tracta de fer el disseny complet d'un sistema de mesura del transport sòlid de fons a rius amb un Helley-Smith HS152. Helley-Smith és com de forma comuna es coneix l'aparell de recerca per prendre mostres puntuals ... -
Effect of sea level variations in the long-term dynamics of the Zandmotor mega-nourishment
(Universitat Politècnica de Catalunya, 2020-06)
Bachelor thesis
Open AccessThe Dutch coast is profoundly threatened by sand erosion and sea level rise due to climate change consequences. In order to keep the country save, the Dutch government is highly implicated in the renourishment of beaches ... -
Effect of stress history on sediment transport and channel adjustment in graded gravel-bed rivers
(European Geosciences Union (EGU), 2021-04)
Article
Open AccessWith the increasing attention on environmental flow management for the maintenance of habitat diversity and ecosystem health of mountain gravel-bed rivers, much interest has been paid to how inter-flood low flow can affect ... -
Effect of the current-wave angle on the local scour around circular piles
