Background, Aim and ScopePast and present management of the Ebro catchment have altered water, sediment and nutrient fluxes of the lower Ebro River and its delta. The construction of the Mequinensa and Riba-Roja dams during the 1960s disrupted the sediment transport continuity. As a result, the lower Ebro River and its delta are facing a reduction in sediment delivery which is estimated to be up to 99% of its original yield (about 3 × 107 t/yr). Consequently, about 45% of the emerged delta will… 
Impact of river regulation on a Mediterranean delta: Assessment of managed versus unmanaged scenarios
This work addresses the effects of the construction of a reservoir 19 km from the mouth on the dynamics of the Guadalfeo delta (southern Spain), a Mediterranean delta in a semiarid and high‐mountain
Environmental Flows in the Lower Ebro River and Delta: Current Status and Guidelines for a Holistic Approach
Deltas are a particular type of estuarine system in which the dependence on river flow (water, sediments and nutrients) is very strong, especially in river-dominated deltas such as the Mediterranean
Sediment imbalances and flooding risk in European deltas and estuaries
The status of current water and sediment management practices in six deltas and estuaries part of the European DELTANET, INTERREG-funded network are analyzed, suggesting that flood risk is the most significant risk, followed by upstream sediment retention and sediment aggradation.
Sustainability of Mediterranean Deltaic and Lagoon Wetlands with Sea-Level Rise: The Importance of River Input
We report on a decadal trend of accretionary dynamics in the wetlands of several northwestern Mediterranean deltas and a lagoon system, all of them with high rates of wetland loss. Wetland vertical
Can we elevate the subsiding coastal plain of the Netherlands with controlled sedimentation?
Abstract. Half the surface area of the coastal plain of the Netherlands has been subsiding below mean sea-level as a result of peatland drainage. At present, the low elevation is sustained, because
Restoring sediment fluxes downstream of large dams: The case of the Lower Ebro River
The construction of dams produces a number of social benefits. But, in producing these benefits, dams also alter the natural balance of sediment flow in rivers by impounding sediment within and

Morphologic development, relative sea level rise and sustainable management of water and sediment in the Ebre Delta, Spain
The Ebre (Ebro) Delta is one of the most important wetland areas in the western Mediterranean. Ca. 40% of the delta plain is less than 0.5 m above mean sea level and part of the southern margin of
Sediment transport in a large impounded river: The lower Ebro, NE Iberian Peninsula
The environmental impact of the Spanish national hydrological plan on the lower Ebro river and delta
The main goal of the Spanish National Hydrological Plan is the implementation of an inter-basin water transfer of a maximum of 1050 hm 3 /year from the lower Ebro River to the north and south
Changes in the hydrology and sediment transport produced by large dams on the lower Ebro river and its estuary
The mean annual flow of the lower Ebro river has reduced by 29% during this century (592 to 426 m3 s−1). The main causes are increased water use and evaporation from reservoirs in the river basin.
Sediment dynamics and hydrodynamics in the lower course of a river highly regulated by dams : the Ebro River
The lowest part of the Ebro River is a microtidal salt-wedge estuary. Penetration of the salt-wedge is largely controlled by the fluvial discharge and the morphology of the river bed, although sea
Fluviatile sediment fluxes to the Mediterranean Sea: a quantitative approach and the influence of dams
Abstract The Mediterranean drainage basin incorporates more than 160 rivers with a catchment >200 km2, of which only a few are larger than 50 × 103 km2: this observation emphasizes the role of the

System functioning as a basis for sustainable management of deltaic ecosystems
Deltas are very important ecologically and economically, and much of the world's coastal wetlands are located in deltas. These areas are in crisis because various human impacts have led to
Recent evolution of a Mediterranean deltaic coastal zone: human impacts on the Inner Thermaikos Gulf, NW Aegean Sea
The Inner Thermaikos Gulf is located in the northwestern Aegean Sea, receiving water and sediment fluxes from the Axios, Aliakmon, Gallikos and Loudias Rivers. The geomorphological and
