GITS - Modelització Integral de Conques i Transport de Sediments
Estudiar l'impacte del transport sòlid en els processos de morfologia i estabilitat de conques a través dels models físics i numèrics. Aprofundir en metodologies de restauració de lleres i riveres. Investigar els processos físics especials com: corrents de densitat, fluxos detrítics en alta montanya, interacció entre flux i vegetació, transport reactiu en rius i fluxos turbulents, resuspensió en embassaments. Interaccionar amb l'entorn extra universitari a través de la formació d'estudiantat de grau, realització de cursos d'especialització i transferència de tecnologia.
GITS trabaja en el estudio del comportamiento de los ríos, su estabilidad y su comportamiento. Desde ríos de alta montaña hasta ríos de planicie dando énfasis a las obras de protección contra la erosión (pilas y estribos de puente) y la inundabilidad (flujos a través de vegetación). Se ha especializado en los últimos años en los flujos detríticos, para lo cual se ha diseñado un modelo físico de laboratorio, un canal de alta pendiente. Ha desarrollado nuevas metodologías para la evaluación del riesgo de inundación para Flash Floods y Debris Flows así como también para sequías: tema del Master Mundus que coordina. Una actividad importante es la consolidación de los laboratorios de Morfodinámica Fluvial I y II. Con capacidad actual para desarrollar más de 6 experimentos diferentes al mismo tiempo. El estudio de los flujos con sedimento de gran importancia en la naturaleza y en su relación con el hombre se ve reforzado en el desarrollo de modelos numéricos propios.
Study the impact of solid transport in basin morphology and stability through numerical and physical models. Deep studies of basin and river restoration methodologies. Research on special physical process such as: density currents, debris flows, interaction between flow and vegetation, reactive transport in rivers and turbulent flows, reservoir entrainment. Interact with extra university researching process through teaching graduate students, specialization courses and technology transference.

The energy transfer from granular landslides to water bodies explained by a data-driven, physics-based numerical model
(2020-10-29)
Article
Open AccessLandslides falling into water can trigger tsunamis, which are particularly destructive in the proximity of the landslide impact and in narrow water bodies. The energy transfer mechanism between landslide and water wave is ... -
Versatile image-based measurements of granular flows and water wave propagation in experiments of tsunamis generated by landslides
(2020-04-01)
Article
Open AccessLandslides falling into water bodies can generate destructive waves, which can be classified as tsunamis. An experimental facility to study this phenomenon has been set up. It consists of a landslidegenerator releasing ... -
Tsunamis generated by fast granular landslides: 3D experiments and empirical predictors
(2017-03)
Article
Open AccessLandslides falling into water bodies can generate impulsive waves, which are a type of tsunamis. The propagating wave may be highly destructive for hydraulic structures, civil infrastructure and people living along the ... -

Coherent structures in oscillatory flows within the laminar-to-turbulent transition regime for smooth and rough walls
(2016-04)
Article
Open AccessWe investigate coherent structures present in oscillatory boundary layers over smooth and rough beds for Reynolds numbers between 103 and 104, in the transition to turbulence regime. A two-camera 2D- particle image velocimetry ... -
Analysis of river bed dynamic evolution following a landslide dam
(2015-12)
Article
Open AccessLandslides and debris flows can strongly interact with the river network and its mass transport processes, determining modifications of the river pattern with consequent effects on the hydrodynamic phenomena, alterations ... -
Morpho-fluvial analysis of headwater catchments: an example from the Central-Eastern Pyrenees
(2015-05)
Article
Open AccessGeomorphometry of headwater catchments has been poorly reported in the Central-Eastern Pyrenees. This study presents a series of parameters obtained for Central-Eastern Pyrenean headwater catchments. The database consists ... -
Experimental studies on 3D impulse waves generated by rapid landslides and debris flows
(2013)
Conference lecture
Open AccessThe input of material in a water body at high velocity, like a landslide or a debris flow, can induce a big, abnormal wave, known as impulse wave or landslide tsunami wave. Once the wave is triggered, the effects on the ... -
