“…El modelo hidráulico 2D Iber® ha sido utilizado en el tramo de estudio para caracterizar la hidráulica durante la extracción. El modelo utiliza datos topográficos y ecuaciones de dinámica de fluidos para simular la lámina de agua en ríos y estuarios (para más detalles consultar Bladé et al, 2014). La parametrización del modelo se ha realizado usando un Modelo Digital del Terreno de 1 metro de resolución (ver Vericat et al, 2016) y un solo valor de rugosidad (n=0,035) basado en los datos granulométricos del tramo.…”

This paper examines the effects of gravel mining on the suspended sediment transport in the Upper River Cinca (Central Pyrenees). Discharge, sediment transport and sediment grain-size distribution were measured, sampled and further determined in five monitoring sections along a 5-km river reach. Samples were taken at a section upstream from the mined area (i.e. reference section) and in four sections downstream (0, 200, 500 and 1500 meters). The results show that sediment concentrations downstream from the target site were up to one order of magnitude higher than in the reference section. Average concentrations during the impact were similar to those observed during floods, with maximum values attaining 6 g/l. Total load ranged from 2.2 to 17 Mg/day between sections; these values include the effects of the earth-moving works performed before the mining started. Concentrations at the lowermost section of the study reach were similar to those observed at the upstream reference section, suggesting that most of the suspended material was deposited in the channel. The transported material was coarse than that sampled under reference conditions; nevertheless, largest particles settled quickly, suggesting a selective transport downstream. This study constitutes a first step towards a better understanding of local sediment dynamics in rivers affected by maintenance works and related activities, such as gravel mining, and, overall, supports the comprehensive assessment of the effects of human actions on channel morphodynamics and the ecological functioning of mountain fluvial systems.

AbstractIn urban areas prone to flash floods, characterization of social resilience is critical to guarantee the success of emergency management plans. In this study, we present the methodological approach that led to the submission and subsequent approval of the Civil Protection Plan of Navaluenga (Central Spain), in which the first phase was to analyse flood hazard by combining the Hydrological Modelling System (HEC-HMS) and the Iber 2D hydrodynamic model. We then analysed social vulnerability and designed measures to put into practice within the framework of the Civil Protection Plan. At a later phase, we assessed citizens' flash-flood risk perception and level of awareness regarding some key variables of the Civil Protection Plan. To this end, 254 adults representing roughly 12% of the population census were interviewed. Responses were analysed descriptively, comparing awareness regarding preparedness and response actions with the corresponding information 2 and behaviours previously defined in the Civil Protection Plan. In addition, we carried out a latent class cluster analysis aimed at identifying the different groups present among the interviewees. Our results showed that risk perception is low. Specifically, 60.8% of the interviewees showed low risk perception and low awareness (cluster 1);24.4% had high risk perception and low awareness (cluster 2), while the remaining 14.8% presented high long-term risk perception and high awareness (cluster 3).These findings suggest the need for integrating these key variables of social risk perception and local tailored information in emergency management plans, especially in urban areas prone to flash-floods where response times are limited.

“…Tras el accidente minero de Aznalcóllar en 1998, se intensificó la recuperación de la cantidad y calidad de las aportaciones hídricas a la marisma, así como de su funcionalidad hidrológica natural. El instituto de investigación Flumen UPC-CIMNE ha participado en esta labor mediante la implementación del modelo numérico bidimensional Iber, que permite conocer los campos de velocidades y profundidades de agua en la marisma ante diferentes escenarios de simulación Bladé et al, 2014;Ramos-Fuertes et al, 2014). También ha participado en el seguimiento de masas de agua y comunidades vegetales mediante teledetección (Martí-Cardona et al, 2010;Marti-Cardona, 2014) y en el estudio hidrometeorológico y de flujos de agua y calor en superficie y fondo (Prats et al, 2011(Prats et al, , 2012Ramos Fuertes, 2012).…”

RESUMENEste trabajo expone los principales resultados del estudio de los balances hídrico y térmico de la marisma de Doñana. El estudio se ha basado en una amplia base de datos hidrometeorológicos tomados a intervalos de 10 minutos entre los años 2006 y 2011 por una red de seis estaciones de medida localizadas en áreas no vegetadas de la marisma. Esta información ha permitido caracterizar, a diferente escala temporal, el comportamiento térmico de la marisma mediante la modelización y análisis de los flujos de calor entre el agua y el suelo inundado, así como los procesos de transferencia de calor entre la superficie libre del agua y la atmósfera. Se ha puesto especial atención en la cuantificación de la evaporación, de la que depende en gran medida el proceso de vaciado de la marisma.Palabras clave | Doñana; balance térmico; balance hídrico; evaporación.
