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 study of the Peña Negra paleoglacier during the Last Glacial Maximum reveals its sensitivity to paleoclimatic variations. The evolutionary phases of the paleoglacier are correlated with the evolutionary models proposed for the Sierra de Béjar-Candelario and the Central Iberian System. To recognize the mechanisms of ice advance/retreat and the r...

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

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...

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...

Virtual fieldtrips in palaeontology and geology offer an expanded environment to make field sites more accessible for a broader audience. Based on extensive experience working in upper Neogene deposits in the province of Huelva, on the western edge of the Guadalquivir Basin, we have selected 10 sites for their regional palaeontological-geological i...

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...

Conventional water treatments when downsized to cover the demands of small and scattered populations are costly and ineffective. In fact, many small towns cannot afford the high average treatment costs nor provide the skill and complex management requirements. Even when these facilities are available, waste water might not be properly treated. Land...

This study focused on the B,jar and Barco tectonic massifs (in the Sierra de Gredos, Spain), in which a large part of the region has been declared a Protected Natural Space.

Data reported by George Bonsor (1918) about damage in the City of Carmona (Sevilla, South Spain) triggered by the AD 1504 Earthquake (X MSK) constitutes the first archaeoseismological report published in the Spanish scientific literature. This work analyses and updates de Bonsor’s data using the ESI-07 Intensity Scale. Most of the described damage...

When making land-use plans, it is necessary to inventory and catalogue the geological heritage and geodiversity of a site to establish an apolitical conservation protection plan to meet the educational and social needs of society. New technologies make it possible to create virtual databases using virtual globes – e.g., Google Earth – and other per...

Downsized conventional water treatment systems as used for small population wastewaters are extremely inefficient. In practice, due to high maintenance and operation costs, their use is frequently discontinued in many small municipalities that cannot afford to treat their wastewater, which is finally dumped untreated. Land Application Systems have...

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...
