Abstract This work addresses the effects of construction a reservoir 19 km from mouth on dynamics Guadalfeo delta (southern Spain), Mediterranean in semiarid and high‐mountain basin. The sediment volume transported as bed load accumulated was estimated under two scenarios by means calibrated hydrological model: managed scenario, considering flows drained dam, an unmanaged absence such infrastructure. Bathymetric topographic measurements were analyzed correlated with fluvial maritime forcing...
Landslides in reservoir contexts are a well-recognised hazard that may lead to dangerous situations regarding infrastructures and people’s safety. Satellite-based radar interferometry is proving be reliable method monitor the activity of landslides such contexts. Here, we present DInSAR (Differential Interferometric Synthetic Aperture Radar) analysis Sentinel-1 images exemplifies usefulness technique recognize Rules Reservoir (Southern Spain). The integration results with comprehensive...
Abstract The impact of climate change on future soil loss is commonly assessed with erosion models, which are suggested to be an important source uncertainty. Here, we present a novel model ensemble assess uncertainty in climate‐change assessments. consists five continuous process‐based models that run at daily time step (i.e., DHSVM, HSPF, INCA, MMF, SHETRAN). were implemented the SPHY hydrological and simulate detachment by raindrop impact, runoff, immediate deposition. was applied...
Coastal regions in Southwest Europe have experienced major interventions and transformations of the territory with unprecedented urban development, primarily related to growing tourism activity. The coast is place where marine terrestrial processes converge, making it highly vulnerable effects climate change. However, lack information on frequency these extreme weather events their impacts hampers an accurate analysis consequences global This paper provides a detailed (EWE) that affected...
Wildfires are a known treat causing relevant impact on the ecosystem, population and economic infrastructures. They becoming more frequent severe due to climate changes, future scenarios now considering their occurrence into currently fire-resistant areas at higher latitudes. Because of this, assessment hazard associated wildfires require also medium long term effects environment. induce physical chemical changes soil with consequent structure losses formation water repellent layers. These...
Abstract. The study of baseflow in mountainous areas basin headwaters, where the characteristics often fractured materials are very different to standard issues concerning porous material applied conventional hydrogeology, is an essential element characterization and quantification water system resources. Their analysis through recession fragments provides information on type response sub-surface subterranean systems average relation between storage discharge aquifers, starting from joining...
This research studies the effect of climate change on hydrological behavior two semi-arid basins. For this purpose, Soil and Water Assessment Tool (SWAT) model was used with simulation future scenarios, one Representative Concentration Pathway moderate (RCP 4.5) other extreme 8.5). Three periods were considered: close (2019–2040), medium (2041–2070), distant (2071–2100). In addition, several climatic projections EURO-CORDEX selected, to which different bias correction methods applied before...
Abstract. The south-central interior of Andalusia experiences intricate precipitation patterns as a result its semi-arid Mediterranean climate and the impact Saharan dust human-made pollutants. primary aim this study is to monitor inter-relations between various factors, such aerosols, clouds, meteorological variables, systems in Granada using ground-based remote sensing situ instruments including microwave radiometer, ceilometer, cloud radar, nephelometer, weather station. Over an 11-year...
Abstract. This paper studies the influence of changing spatial resolution on implementation distributed hydrological modelling for water resource planning in Mediterranean areas. Different cell sizes were used to investigate variations basin hydrologic response given by model WiMMed, developed Andalusia (Spain), a selected watershed. The was calibrated monthly basis from available daily flow data at reservoir that closes watershed, three different sizes, 30, 100, and 500 m, effects this...
Abstract Soil loss, fluvial erosion, and sedimentation are major problems in semi‐arid environments due to the high associated costs of decreasing services such as provisioning regulating water resources. The objective this research is analyse sediment yield a mountainous basin, paying special attention sources sediment, uncertainties, transport processes involved. segregation hypothesis along reservoir coming from hillslopes or systems also evaluated. For purpose, bottom‐set deltaic...
To assess seasonal patterns of suspended sediment load and its erosion–transport interactions, 17 years river monitoring data from the Isser River Basin (northwest Algeria) were studied, considering continuous event-scale approaches. The results show significant differences in yield transport processes between dry wet periods. A rate 8 t ha−1 year−1 was estimated analysis, with values 4.3 13 for periods, respectively. Estimates soil delivery ratio pointed to higher during periods dominance...
Abstract. Regulation by reservoirs affects both the freshwater regime and sediment delivery at area downstream, may have a significant impact on water quality in final transitional bodies. Spain is one countries with more storage capacity world. Dense reservoir networks can be found most of hydrographic basins, especially central southern regions. The spatial redistribution seasonal annual for irrigation urban supply, mainly, has resulted changes flow load regimes, together fostered...
Abstract Understanding erosion and sediment transport dynamics is key for sustainable water resources management. The objective of this research was to assess suspended responses, identifying relationships with hydro‐meteorological drivers, sources connectivity in a mountainous semi‐arid basin. With purpose, concentrations 12 events were measured by automatic sampling classified based on six descriptors their related rating curves hysteresis loop behaviour, distribution precipitation,...
Estuarine water in Mediterranean basins has high concentrations of suspended sediment. In order to study the temporal and spatial distribution turbidity, a monitoring network with sufficient resolution is needed monitor quality, this not always available. Thus, over last few years, satellite images have been used as an alternative way estimate quality parameters, such turbidity. The Guadalquivir River estuary south-west Spain extends for 105 km one world's most turbid estuaries. sediments...
Abstract. Risk assessment for water resource planning must deal with the uncertainty associated excess/scarcity situations and their costs. The projected actions increasing security usually involve an indirect "call-effect": territory occupation/water use is increased following achieved protection. In this work, flood demand in a mountainous semi-arid watershed southern Spain are assessed by means of stochastic simulation extremes, when human factor is/is not considered. results show how...
