      Among other remarkable impacts, the most important effect of gravel mining in rivers is river bed degradation. Although there are some methodologies proposed to foresee the effects of gravel mining (giving bed degradation ...
    • Mathematical modeling for incision and width changes caused by gravel mining 

      Ferrer Boix, Carles; Martín Vide, Juan Pedro (CRC Press, 2009)
      Conference report

      Among other remarkable impacts, the most important effect of gravel mining in rivers is riverbed degradation. Channel-width changes associated to riberbed incision play a major role in this process. Bed incision is coupled ...
    • Morfología del río Ebro en el estiaje de 1863 y deducción de un caudal mínimo 

      Capapé Miralles, Sergio; Martín Vide, Juan Pedro (2012-03)
      Article
      Open Access
      La transformación del territorio fluvial ha sido una constante desde los primeros asentamientos en las orillas de los ríos. El trabajo realizado en 1863 por De Mesa Arroquia ofrece una visión del valle del Ebro cuando los ...
    • Numerical model for channel evolution after dam removal in a sand-gravel bed mixture 

      Ferrer Boix, Carles; Martín Vide, Juan Pedro; Parker, Gary (Tsinghua University, 2011)
      Conference report
      Restricted access - publisher's policy
      Dam removal is a common tool for river restoration. Once a dam is removed an incised channel is developed in the upstream deposit. Material eroded from this deposit is flushed away downstream. Even though dam retirement ...
    • Porosity and size gradation of saturated gravel with percolated fines 

      Núñez González, Francisco; Martín Vide, Juan Pedro; Kleinhans Maarten, G. (2016-08)
      Article
      Open Access
      Fine particles may infiltrate through coarse alluvial beds and eventually saturate the subsurface pore space. It is essential to understand the conditions that lead to bed saturation, and to forecast the packing characteristics ...
    • River incision due to gravel mining: a case study 

      Martín Vide, Juan Pedro; Ferrer Boix, Carles (2006)
      Conference report
      Restricted access - publisher's policy
      Historical information was used to study river degradation in a case study in NE Spain. The accumulation of good topographical information since the 1940s for the Gállego river (a tributary of the Ebro river, which drains ...
    • Sorting of a sand-gravel mixture in a Gilbert-type delta 

      Ferrer Boix, Carles; Martín Vide, Juan Pedro; Parker, Gary (2015-08)
      Article
      Open Access
      This paper presents the results of a Gilbert-type delta progradation experiment within an impoundment created by a dam. The delta was composed of a poorly sorted sand-gravel mixture in a bedload-dominated environment. The ...
    • Subaqueous barchans and plane beds from deposition of quartz silt 

      Capapé Miralles, Sergio; Martín Vide, Juan Pedro; Colombo Piñol, Ferran (2016-12-01)
      Article
      Open Access
      The suspension flow of quartz silt (geometric mean grain size of 4.15 µm), in unfavorable conditions for deposition, is the motivation for the development of different bed morphologies. Particles deposit over a plane ...
    • Suspended sediment load at the lowermost Ebro River (Catalonia, Spain) 

      Rovira Garcia, Albert; Ibáñez, Carles; Martín Vide, Juan Pedro (2015-11)
      Article
      Open Access
      Several attempts to estimate the suspended load and the sediment deficit caused by the reservoirs have been carried out in the lower Ebro River. However, existing data are scarce, scattered along time and space, and obtained ...
    • The 1962 flash flood in the Rubí stream (Barcelona, Spain) 

      Martín Vide, Juan Pedro; Llasat Botija, Carmen (Elsevier, 2018-11)
      Article
      Open Access
      The 1962 Rubí flood was a severe flash flood, the worst to ever take place in Spain, claiming the lives of more than 800 people following 200¿mm of rainfall in 2¿h. Such a high number of casualties can be explained by the ...
    • Transient scour and fill: the case of the Pilcomayo River 

      Martín Vide, Juan Pedro; Capape, Sergio; Ferrer Boix, Carles (Elsevier, 2019-09)
      Article
      Open Access
      Transient scour and fill refers to the general scour and fill in a riverbed due to flood passage. It was given much attention in times of Leopold and Maddock (1953) and Colby (1964) from records of outstanding case studies. ...
    • Uso de modelos uni- y bidimensionales en llanuras de inundación. Aplicación al caso del río Tajo en Talavera de la Reina 

      Martín Vide, Juan Pedro; López Querol, Susana; Martín Moreta, Pedro; Simarro Grande, Gonzalo; Benito Ferrández, Gerardo (Fundación para el Fomento de la Ingeniería del Agua, 2003-03)
      Article
      Open Access
      En este trabajo se presenta la experiencia de uso de un modelo hidráulico unidimensional (Hec- Ras) y uno bidimensional (Feswms) en el estudio de la inundabilidad de Talavera de la Reina por el río Tajo. Se revisan los ...
    • What controls the coarse sediment yield to a Mediterranean delta? The case of the Llobregat River (NE Iberian Peninsula) 

      Martín Vide, Juan Pedro; Prats Puntí, Arnau; Ferrer Boix, Carles (2020-12)
      Article
      Open Access
      The human pressure upon an alluvial river in the Mediterranean region has changed its riverine and deltaic landscapes. The river has been channelized in the last 70 years while the delta has been retreating for more than ...
