The large pier of an emblematic bridge built in 2008 in the Ebro River (Zaragoza, Spain) obstructs the flow in high floods. Clear-water scour experiments in a scale model were conducted to anticipate maximum local scour depths and design riprap protections. These proved to be effective during a large flood event in 2015, but bed aggradation under t...
Article
In this research, we explore the alluviation process of an artificial side-channel built in August 2015 and designed to alleviate bank erosion risks on the main river. The study area is located on the lower Gállego River, a meandering-wandering gravel-bed river draining the Southern Pyrenees. This river reach is still dynamic (i.e. chutes, meander...

Different base level scenarios have been imposed to a sand-gravel laboratory Gilbert delta to gain insight on its dynamics under varying base level. Base level rise results in intensified aggradation over the topset, as well as a decrease in topset slope and topset surface coarsening, the signals of which migrate in an upstream direction. Preferent...

The methodology and results of two dam removals in two different rivers is presented and compared. One removed all-at-once and the second one in a four-stage removal process. Methodology included topographical measurements of the channel, TLS measurements of river bed and bars and sediment grain size and transport. Morphological channel adjustments...
Article
Dam removal has been demonstrated to be one of the most frequent and effective fluvial restoration actions but at most dam removals, especially of small dams, there has been little geomorphological monitoring. The results of the geomorphological monitoring implemented in two dams in the rivers Urumea and Leitzaran (northern Spain) are presented. Th...

Longitudinal profiles of alluvial rivers usually exhibit upward-concave curvatures at equilibrium. River profile concavity has been primarily attributed to sediment downstream fining and to streamwise increments of water discharge. Conversely, upward-convex profiles have been typically associated with tectonic and geologic controls and with outlet...
Article
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 of saturated beds to assess the effect of excess fine sediment supply on a number of processes that occur in the stream-se...

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 main goal of the paper is to analyze the sorting process of material within the deposit as the delta progrades towards the dam....
Article
Dam removal is commonly used for river restoration. However, there are still some uncertainties associated with dam removal, mainly related to the sediment transport rates released downstream from the deposit that had previously filled the impoundment. This research studies the physical response to dam removal in the antecedent deposit by answering...

La dinámica de las formas fluviales (morfodinámica) tiene cada vez más presencia en la planificación de los ríos, pero sus objetivos, alcance y métodos no están consolidados. El río Fluvià en Cataluña (NE de la península Ibérica) tiene una notable movilidad y en él se planea la restauración de meandros cortados por canalizaciones. Este artículo exp...
Article
Although the use of fluvial dynamics (morphodynamics) is increasingly used in the planning of rivers, the aims, scope and methods of morphodynamic studies have not been developed. The restoration of meanders cut by channels is planned for the Fluvia River in Catalonia (northeastern Iberian Peninsula), which is notably mobile. This papers explains w...
Article
Antidunes are bed forms characteristic of upper regime unidirectional flows. Contrary to bed forms developed in lower regime flows, antidunes not only can propagate in the downstream direction but can propagate upstream or remain stationary. In this work we analyze the stable hydraulic conditions that determine each of the three antidune movement p...

Protection of banks against erosion is an important but very expensive task in river management. The outer banks in river bends are most vulnerable to erosion and require an enhanced protection. This paper investigates, in an experimental flume, the efficiency of scour reduction and bank protection near the outer banks in open-channel bends by mean...

... Detection implies identifying a trend that cannot be solely explained by natural variability, while attribution means that the detected trend cannot be explained if a specific pre-identified human disturbance is excluded. As has been recently recognized by others (e.g., Downs and Piégay, 2019;Martín-Vide et al., 2020), this distinction is important and has many implications for studies in fluvial geomorphology. ...
... At the site scale, river morphology could also have a crucial impact on such ecological processes. For instance, meandering rivers have more complexity of overbank flow than straight rivers, and the roughness can reduce the floodplain velocities (Moreta and Martín-Vide, 2020;Shiono et al., 2009). In addition, meandering rivers are of higher sinuosity and the ability to reduce flowing velocity, hence, meandering rivers could have a lower erosion potential in the concave sections. ...

The runs are made with the 1D research code Elv (Blom et al. 2016(Blom et al. , 2017aChavarrías et al. 2018aChavarrías et al. , b, 2019Arkesteijn et al. 2019Arkesteijn et al. , 2021) (Appendix S1). It combines the backwater equation (e.g., Parker 2004), a Manning-Strickler roughness closure (Parker 1991), the Hirano equation (Hirano 1971), the regularization strategy proposed by Chavarrías et al.

... The flute casts are erosive structures that are produced by the movement of a fluid over a cohesive substrate and are caused by erosion of freshly deposited mud on an underwater slope (turbidity current) (Ricci-Lucchi, 1995 ). The groove casts are produced by flow of currents on soft mud (Crowell, 1955; McBride, 1962).The antidunes are characteristic of supercritical and subcritical flow conditions (González and Vide, 2010). These are also characteristic products generated under upper flow regime (Gilbert, 1914). ...
... Seven economically, socially, and environmentally dynamic urban towns across coastal natural protected areas in Mediterranean Spain, the Ebro Delta (see Case Study 8.1 Figure 1), and Empordà wetlands have been particularly vulnerable to three aspects of climate change: (1) air and sea temperatures rise (2) sea level rise, and (3) decreased river flows (see Case Study 8.1 Table 1). In addition, intensification of coastal erosion, flooding, saltwater intrusion, and deficits in river sediment supply have been affecting natural habitats and livelihoods in these areas (Barnolas and Llasat, 2007;Candela et al., 2007;CIIRC, 2010;Day et al., 2006;Guillén and Palanques 1992;Jiménez et al., 1997;Martín-Vide et al., 2012;Sánchez-Arcilla et al., 2008). This paper is based on studies that identified a local dimension of climate change adaptation relevant for maintaining a wide range of livelihoods while facing current and future climate change (Fatorić, 2010(Fatorić, , 2014. ...
... It is also an index that can give us a better picture about erosivity or aggressiveness of precipitation and its effects on soil erosion than the usual indices based on monthly precipitation (Bessaklia et al. 2018), such as the monthly precipitation concentration index developed by Oliver (1980) and the modified Fournier Index developed by Arnoldus (1980). This is an important subject in many countries because erosion reduces soil fertility, modifies the conditions for crops, alters agricultural practices and causes the rapid clogging of reservoirs (Scholz et al. 2008;Ibisate et al. 2016). There are two country groups more affected by soil erosion: very arid countries with poor vegetation cover and countries with high precipitation. ...
... iles (Leopold and Maddock, 1953;Sinha and Parker, 1996), while the reduction in Qw downstream contribute to the convexity of the channel profile. In this sense, ephemeral streams typically show a notorious reduction in Qw along their trajectory (Martín- Vide et al., 1999;Bull, 2007), often associated with a rectilinear profile (Powell et al., 2012;Ferrer-Boix. 2016) or slightly convex one (Heede, 2004). The decrease in discharge downstream in these types of watercourses is often related to high rates of permeability that occur on their granular beds, especially of sand and gravel. The result Is a constant slope in most of the profile. ...
... In the fluvial context, sieving a sample through a hierarchy of sieves is the standard method to quantify the size distribution, reported as the histogram-like sieving curve. These studies led to the development of mathematical models for specific size distributions [9], empirical models based on certain characteristics like the median grain diameter D 50 or the standard deviation [5,[10][11][12], or more general theoretical mixing models [13,14]. Still, when applying these porosity models for sediment deposits and comparing their prediction to experimental measurements, their predictive capabilities are rather limited [3,5], suggesting that other effects interfere in the general case. ...

Predicting bed load transport is particularly relevant to several disciplines: river engineering, river morphology, river ecology , reservoir management, environmental engineering, dispersion of pollution and prediction of natural disasters (for example, Martín-Vide, 2013; Re, Kazimierski, & Menéndez, 2014).

... Heng and Suetsugi (2014) observed that a combined formulation of catchment similarity and regression is an appropriate tool for extraction of sediment rating curve in ungagged rivers. Rovira et al. (2015) used field data to evaluate the effects of dam construction on SSL. Bezak et al. (2014) showed that the Gumbel-Hougaard copula is the best three-dimensional copula for modelling SSL, peak discharge, and volume of flood hydrograph. ...
