Dynamics of suspended sediment borne persistent organic pollutants in a large regulated Mediterranean river (Ebro, NE Spain)
(Elsevier, 2013)Mediterranean rivers are characterized by highly variable hydrological regimes that are strongly dependent on the seasonal rainfall. Sediment transport is closely related to the occurrence of flash-floods capable to deliver ... -
Water research in the Mediterranean: challenges and perspectives. The Catalan Institute for Water Research (ICRA)
(Institut d'Estudis Catalans, 2014)The mission of the Catalan Institute for Water Research (ICRA) is to implement a holistic, multidisciplinary approach to water research, taking into account all components related to freshwaters and human-used waters. The ... -
Evaluation of bed load transport formulae in a large regulated gravel bed river: The lower Ebro (NE Iberian Peninsula)
(Elsevier, 2014-03-14)This paper tests the predictive power of 10 bed load formulae against bed load rates obtained for a large regulated river (River Ebro) the armor layer of which is subject to repeated cycles of break-up and reestablishment. ... -
Evaluación de fórmulas de transporte de fondo en un río de gravas acorazado
(Instituto Mexicano de Tecnología del Agua (IMTA), 2015)El curso bajo del río Ebro (NE península Ibérica) presenta un cauce con lecho de gravas que discurre aguas abajo de un complejo de embalses. En dicho tramo, el lecho experimenta ciclos de rotura y restablecimiento de la ... -
Historical, hydraulic, hydrological and meteorological reconstruction of 1874 Santa Tecla flash floods in Catalonia (NE Iberian Peninsula)
(Elsevier, 2015-02-16)A multidisciplinary methodology for historical floods reconstruction was applied to 1874 Santa Tecla floods occurred in Catalonia (NE Iberian Peninsula), using both historical information and meteorological data from 20th ... -
From experimental plots to experimental landscapes: topography, erosion and deposition in sub‐humid badlands from Structure‐from‐Motion photogrammetry
(John Wiley & Sons, Ltd., 2015-04-22)In the last decade advances in surveying technology have opened up the possibility of representing topography and monitoring surface changes over experimental plots (<10 m2) in high resolution (~103 points m‐1). Yet the ... -
Improvement of flood frequency analysis with historical information in different types of catchments and data series within the Ebro River basin (NE Iberian Peninsula)
(Gebrüder Borntraeger Verlagsbuchhandlung, 2015-10-29)The use of historical information is acknowledged to improve frequency analysis. However, it is not well known if the degree of this improvement depends on the characteristics of both the catch-ment and the data series. ... -
Effects of flow regulation on river bed dynamics and invertebrate communities in a Mediterranean river
(Springer International Publishing, 2016)Mediterranean rivers are hotspots for biodiversity, and riverine species are adapted to regular physical perturbations that affect channel morphology during flashy rainfall-runoff events. Dams alter flow regimes, ... -
Meteorological and hydrological analysis of major floods in NE Iberian Peninsula
(Elsevier, 2016-10)This paper analyses the meteorological conditions and the specific peak flows of 24 catastrophic floods that affected NE Iberian Peninsula in the period 1842-2000. We classify these floods according to the affected area, ... -
Application of Structure‐from‐Motion photogrammetry to river restoration
(John Wiley & Sons, 2016-11-08)Structure‐from‐Motion (SfM) photogrammetry is now used widely to study a range of earth surface processes and landforms, and is fast becoming a core tool in fluvial geomorphology. SfM photogrammetry allows extraction of ... -
Dinámica Geomorfológica del frente costero del valle de Teixedelo (NO Península Ibérica) entre 1945 y 2014
(Departamento de Geografía, FAUG de la Universidad de la Concepción, Chile, 2017-05-17)Se ha estudiado la dinámica de un sector de los acantilados de A Capelada (Galicia, NO Península Ibérica), lugar de gran interés por su constitución geológica, geomorfológica y de paisaje. El rasgo más singular de la fachada ... -
The importance of a small ephemeral tributary for fine sediment dynamics in a main‐stem river
(John Wiley & Sons, 2017-07-21)Studies of ephemeral streams have focused mainly in arid and semi‐arid regions. Such streams also occur widely in temperate regions, but much less is known about their influence on fluvial processes in main‐stem rivers ... -
The fluvial sediment budget of a dammed river (upper Muga, southern Pyrenees)
(Elsevier, 2017-09-15)Many rivers in the Mediterranean region are regulated for urban and agricultural purposes. Reservoir presence and operation results in flow alteration and sediment discontinuity, altering the longitudinal structure of the ... -
Multiple stressor effects on biological quality elements in the Ebro River: Present diagnosis and predicted responses
(Elsevier, 2018)Multiple abiotic stressors affect the ecological status of water bodies. The status of waterbodies in the Ebro catchment (NE Spain) is evaluated using the biological quality elements (BQEs) of diatoms, invertebrates and ... -
Asynchronicity of fine sediment supply and its effects on transport and storage in a regulated river
(Springer, 2018)Purpose A disconnected ephemeral tributary was reconnected to the regulated River Ehen (NW England) as part of a river restoration initiative, providing a renewed delivery of sediment to a highly stable and armoured ... -
Accuracy assessment of digital terrain model dataset sources for hydrogeomorphological modelling in small Mediterranean catchments
(MDPI, 2018)Digital terrain models (DTMs) are a fundamental source of information in Earth sciences. DTM-based studies, however, can contain remarkable biases if limitations and inaccuracies in these models are disregarded. In this ... -
Transport of sediment borne contaminants in a Mediterranean river during a high flow event
(Elsevier, 2018)Pollutants' dynamics in rivers flowing through industrial areas is linked to the entrainment and transport of contaminants attached to solid particles. The transport of sediment is mainly associated to high discharges and ... -
