A detailed geomorphological mapping allowed to understand the complex relationships interplayed between local tectonics and sedimentation across the coastal area of the Baixo Alentejo (Portugal) all along the Qua-ternary. Different outcrops of coastal sediments between Sines and Vilanova de Milfontes permitted to reconstruct a general sequence of u...

The dune fields of the National and Natural Parks of Doñana are considered one of the most outstanding dune fields in Western Europe. They are located at the west margin of the Guadalquivir river estuary. The accumulation of aeolian sands partly blocks the connection between the ample Guadalquivir River estuary and the Gulf of Cádiz in the Atlantic...

The volcanic Cape Verde archipelago constitutes one of the few sites in low latitude eastern Atlantic Ocean, where a long record of Pleistocene sea-level indicators develops, particularly beach deposits and marine terraces. The extreme aridity of the easternmost islands (Sal, Boa Vista and Maio) allows the exposure of long sedimentary sequences, th...

The recent geodynamic evolution of Iberia is recorded in its topography. Geomorphic markers and their dating; morphometric indices estimated through cutting-edge DEM analysis techniques; and the link of all this data with results of geophysical studies allow discussing why Iberia displays the highest average elevation in Europe and shows a particul...

This article analyzes the coastal vulnerability and flood risk due to sea level rise in the Menor Sea, Murcia (Spain).

The different morphogenetic systems are used to establish a comprehensive evolutionary analysis, contrasting the depositional systems found in the continent...

The present work envisages the possible geometry of a contaminated plume of groundwater near hospital facilities by combining GIS (Geographic Information System) and geophysical methods. The rock underlying the soil and thin sedimentary cover of the study area is moderately fractured quartzite, which makes aquifers vulnerable to pollution. The GIS...

Geological indicators of former sea level can be considered an accurate tool for determining coseismal vertical displacements. However, sea level markers do not always offer the same degree of reliability. Coastal deposits or marine terraces do not mark by themselves the datum level (±0 m). Differences in altitude amsl in present beaches can reach...

This paper presents a mapping procedure for risk mapping of water and wind erosion, which helps to identify protective measures needed in the planning and management of natural parks. The map of water erosion risk was developed by combining the original and revised universal soil loss equation methodologies (USLE-RUSLE), and the map of wind erosion...

Trying to decipher how paleoseismic activity has influenced the altitudinal disposition of interglacial deposits is one of the main challenges to be confronted before quantifying relative sea-level changes between consecutive highstands. At the same time, identifying paleoseismic features in an area with low instrumental seismic activity can comple...

To correctly and rationally plan human activities in fragile conservation areas, an exhaustive study of the soil forming factors (climate, lithology, geomorphology, topography, hydrology and vegetation) including the soil relationships, must be conducted. We analysed the geospatial distributions of different soil types in the “Las Batuecas - Sierra...

Seismic Intensity scales are based on the effects of earthquakes on man, man-made structures and on natural environment. However, the effects on the environment have been usually minimized because they were considered as inaccurate features. The growth of Palaeoseismology as an independent discipline led to the development of the ESI-2007 Intensity...

Doñana Natural Park is a good global example of the sedimentary filling of a broad tidal estuary during the Mid-Late Holocene, after the last postglacial sea-level rise. The timing of this rise is not well defined yet in the Gulf of Cádiz, since the oldest evidence of coastal sedimentation, located at the right bank of the mouth of the old Guadalqu...

Ground movements constitute active processes that modify the disposition and morphology of the earth’s surface. This work establishes a cartography procedure to obtain a ground movement risk map at a 1:50,000 scale. Such a map would be useful for establishing mitigation measures for land use planning and management in natural spaces, using Geograph...

The Calabrian Stage is now formally defined by the Global Boundary Stratotype Section and Point (GSSP) at Vrica, Calabria, Italy. This GSSP had previously defined the base of the Pleistocene Series. The Calabrian becomes the second stage of the Pleistocene Series and Quaternary System, following the Gelasian. The GSSP occurs at the base of the mari...

Cartographic analysis of the hazard of erosion is a useful tool for the planning and management of natural parks, helping to establish measures for protection and correction. Such parks, which offer spectacular landscape views and natural beauty, must be conserved with all their resources. Accordingly, park managers must have the cartographic tools...

Many on-shore studies focused on high energy marine events occurred in the Gulf of Cadiz have been published since the 1990s. Most of the findings came from sedimentary, palaeontological and geomorphological records on estuaries, marshes, beach-barriers (spit-bars), and some coastal lowlands. Recent off-shore investigations in SW Iberia considered...

Detailed reconstructions of the vegetation of Iberia during the last glacial inception are rare due to the limited number of terrestrial sites recording this period. Active retreat of El Asperillo cliff, located on the Atlantic coast of southwestern Iberia, has exposed a fossil organic level dating back to one of the early stades of the last glacia...
