Procesos deposicionales y antrópicos en el registro holoceno de la Cova de Can Sadurní (Begues, Barcelona, España): aportaciones microestratigráficas

El estudio geoarqueológico y microestratigráfico de la secuencia de la Cova de Can Sadurní (Begues, Barcelona) ofrece una variabilidad de procesos deposicionales de tipo detrítico y antrópico que en determinadas etapas se alternan y repercuten en los procesos diagenéticos localizados. La secuencia cultural del yacimiento va desde el Epipaleolítico hasta época Romana bajo imperial con algunas interrupciones cronoculturales. Durante el Epipaleolítico y Mesolítico los aportes solifluidales son los responsables de la sedimentación. A partir del Neolítico, movimientos de masa y procesos coluvionales son los dominantes. Se distinguen flujos densos principalmente durante el Neolítico antiguo cardial y postcardial inicial; también se localizan pero con menor extensión durante el Neolítico medio postcardial, Neolítico final/Calcolítico y en el Bronce inicial. Los aportes coluvionales no laminados aparecen en el resto de la secuencia. Estos episodios se alternan con fases de estabilidad en el medio en el que la tasa de sedimentación detrítica es menor o casi inexistente y es reemplazada por los aportes procedentes de las actividades de estabulación localizados in situ durante el Neolítico epicardial y postcardial inicial; aunque ya se constaten evidencias desde el Neolítico antiguo cardial. Asociados a estos contextos, los procesos hidromórficos se acentúan dando lugar a la formación de vivianita, fosfato de hierro, propia de lugares reductores con un gran contenido orgánico

Karst in conglomerates in Catalonia (Spain): morphological forms and sedimentary sequence types recorded on archaeological sites

This article aims to make the karst morphological forms to be found in conglomerate rocks, as well as the sedimentary sequence types recorded in such deposits, more widely known. Particular attention is paid to points where prehistoric occupation has been traced, sites such as: the Font Major Cave (Espluga de Francoli, Tarragona), the Hort de la Boquera, the Filador Rock-shelter and the Colls Rock-shelter (Margalef de Montsant, Tarragona), and the Parco Cave (Alôs de Balaguer, Lleida). By means of this approach the characteristics of karst deposits in conglomerate rocks are analyzed both from an archaeological and a sedimentary point of view

Planned vs. real city: 3D GIS for analyzing the transformation of urban morphology

Cities are constantly evolving: buildings are built and demolished, altering the landscape of our cities; Urban Plans describe what we want our cities to be, undergoing revisions as we change our vision of the future of our cities. This paper presents a methodology to model the interactions between what the city is and what it wants to become. The old quarter of Sant Andreu in Barcelona (Spain) was used in a pilot study for the development of a methodology to automatically quantify and visualize the outcome of regulation changes as a strategic tool for the Urban Planning Department of the Barcelona City Council. This paper describes a methodology developed to measure the magnitude of the buildings conformity or disconformity to the determinations of the Urban Plan (current and proposed), and to display this information in 3D, to allow a more natural interpretation of the results. Special care was put into the methodological approach to ensure that it could be replicated at neighbourhood or city-wide scales. A methodology for the interpretation of the heights of staircase towers and ventilation courtyards from neighbouring entities heights, through the analysis of adjacency relationships in a non-topological Geographic Information System is also discussed.Postprint (published version

SIG para la gestión eficiente de la información urbanística local

La dificultad de hacer el seguimiento del grado de cumplimiento del planeamiento urbanístico con la realidad construida y cambiante en la ciudad, demanda el uso de herramientas de Sistemas de Información Geográfica (SIG) en la gestión local para desarrollar y mantener un conocimiento preciso de las características físicas, urbanas y económicas del parque inmobiliario, así como de las determinaciones de planeamiento que afectan a los valores de su potencial edificable y urbano. En este trabajo se propone implementar un nuevo proceso innovador para el estudio y la gestión de la ciudad con SIG, dónde se establecen las pautas para obtener el potencial urbanístico de un ámbito, un barrio o una ciudad, a partir de la comparación de la realidad existente con el planeamiento urbanístico, detectando de manera automática tanto las parcelas que no agotan su potencial como las que están sobreedificadas. Para ello se ha realizado un estudio piloto en el núcleo antiguo del barrio de Sant Andreu de Barcelona, el cual está en un proceso de modificación del planeamiento general vigente, afrontando el reto de desarrollar nuevas herramientas que permitan emular las consecuencias de las modificaciones y acometer una gestión eficiente de la información urbanística local.Peer Reviewe

Gis technologies for the analysis of the office's properties in Barcelona

The changes in the characteristics and needs for space for the economic activity, the increasing predominance of tertiary industry of offices or I+D, produced for the economic changes, implies new forms, new technical characteristics and similar alternative locations to a changeable and increasing demand. This work makes the bases to a geographical information system channelled to the property geo-marketing for office blocks in Barcelona, which allows the necessary information on the constructive and technical characteristics of the office blocks, summoned in the most emblematic locations of greatest centrality or of greater technical level in its constructions towards facilitating the maximum knowledge to the citizen in order to assure the choice but suitable according to the needs for every profile of demand. This work consisted basically in the definition of technical criteria to evaluate the buildings, to systematize those characteristics in some indicators (variables) capable of expressing the level of quality, to establish a system of measure for bigger to smaller values explained by quality. Systematizing the collection of information of a total of 683 buildings of Barcelona and of some municipalities of its periphery, through a visit to every building, to process the data obtained to a database and to standardize the value of quality for every indicator and set of indicators towards determining a final qualification, obtained from the different physical, constructive and qualitative characteristics of every studied building. Finally an analysis of them is carried out according to its location, according to certain parameters that differentiate them and itself realize an analysis according to a statistical model of hierarch zing of them.Peer Reviewe

Aproximació a l'estudi sedimentològic i paleoclimàtic d'un assentament prehistòric: la Cova del Parco (Alòs de Balaguer, La Noguera)

The cave of Parco is found in the pre-Pyrenean massif of Montsec, in the northern interior region of Catalonia, an area dominated by a present day arid or semiarid climate. The deposit, opened up in sections, is made up of a single gallery cave which communicates to the west with a shelter. In this study a sedimentological analysis of one stratum with a thickness of 2.38 m. consisting of sterile strata of the end of the Upper Paleolithic, Epipaleolithic and Neolithic periods is described. The fifteen layers studied are grouped into four stratigraphic and sedimentological units. Finally the sedimentary, paleogeographical and paleoclimatic evolution of the area is calculated. For the latter six regional climatic pulses are proposed ranging from the end of Upper Pleistocene to Atlantic
