- Metodologias de análise e de classificação das paisagensPublication . Ferreira, António Brum; Alcoforado, Maria João; Vieira, Goncalo; Mora, Carla; Jansen, JanAssiste-se actualmente ao renascimento dos estudos de «Ecologia da Paisagem», mas continua a verificar-se uma grande dispersão, não só nos métodos, mas também no próprio objecto e nas escalas espacial e temporal de análise. Os progressos dos métodos quantitativos e dos sistemas de informação geográfica têm conduzido muitas vezes a uma excessiva preocupação pelos padrões fisionómicos, em detrimento da dinâmica da paisagem. Por sua vez, o entendimento da paisagem como um «geossistema» tem enfrentado a dificuldade do cálculo dos fluxos de matéria e energia, que exige meios poderosos só ao alcance de alguns laboratórios. O estudo integrado do ambiente físico, mesmo num plano mais modesto, de análise mais descritiva e cartográfica do que quantitativa, exige uma investigação pluridisciplinar, defendida por muitos mas raramente posta em prática. O projecto de investigação ESTRELA tem como objectivo o estudo das relações entre a fisionomia e a dinâmica da paisagem, num ambiente de montanha, através da análise geomorfológica, climatológica e da vegetação, utilizando três escalas espaciais de análise. Referem-se os trabalhos efectuados em cada um desses domínios, dá-se um exemplo de tentativa de integração de pesquisas sectoriais e remata-se com uma perspectiva temporal da transformação da paisagem na Serra da Estrela. Um dos problemas ainda não resolvidos consiste nos critérios a adoptar na definição das unidades de paisagem
- Avaliação de recursos hídricos através de modelação hidrológica: aplicação do programa VISUAL BALAN v2.0 a uma bacia hidrográfica na Serra da Estrela (Centro de Portugal)Publication . Espinha Marques, Jorge; Samper, Javier; Pisani, B. V.; Alvares, D.; Vieira, Gonçalo; Mora, Carla; Carvalho, C.; Chaminé, Helder; Marques, J. M.; Sodré Borges, F.Numerical models are needed to evaluate complex hydrological systems. VISUAL BALAN v2.0 is a lumped hydrological code which performs daily water balances in the soil, the unsaturated zone and the aquifer requiring a small number of parameters. VISUAL BALAN has been used to model the river Zêzere catchment upstream of Manteigas (Serra da Estrela, Central Portugal), in order to assess its water resources. Modelling started with the definition of sub-basins based on hydrogeomorphological units. Then, daily temperature and precipitation data from Manteigas meteorological station were extrapolated to each sub-basin considering vertical gradients. Finally, modelling with VISUAL BALAN was performed in four stages: (i) physical characterisation of each sub-basin; (ii) preliminary calculations of the daily water balance; (iii) model calibration by means of flow measurements in the river Zêzere; (iv) result analysis. This basin exhibits complex patterns in hydrometeorological variables such as rainfall and temperature. Several sub-basins have been defined in order to account for the spatial variability in hydrometeorological and geomorphological variables. The model reproduces observed flowrates while its results are coherent with the conclusions of previous studies in similar basins.
- Combined numerical and Geomorphological reconstruction of Serra da Estrela plateau icefield, Portugal.Publication . Vieira, GoncaloThe paper focuses on reconstruting a plateau icefield susface from field geomorphoçogical data and a physical-based glaciar model. The results allow the analysis of the patterns of glacial erosion and estimation of the palaeo-Equilibrium Line Altitudes (ELA). The study area is the Serra da Estrela, a plateau in Central Portugal rising to ~2000 m ASL. The glaciated area during the Last Maximum of the Serra da Estrela Glaciation (LMGSE) was ~66km2. The reconstrution of the topography of the icefield and vlley glaciers in the LMGSE is based on the Schiling and Holin model.
- Evaluation of water resources in a high-mountain basin in Serra da Estrela, Central Portugal, using a semi-distributed hydrological modelPublication . Marques, Jorge Manuel Espinha; Samper, Javier; Pisani, B.; Alvares, D.; Carvalho, José Martins; Chaminé, Helder I.; Marques, José Manuel V. Barbosa; Vieira, Goncalo; Mora, Carla; Borges, Frederico SodréHigh-mountain basins provide a source of valuable water resources. This paper presents hydrological models for the evaluation of water resources in the highmountain Zezere river basin in Serra da Estrela, Central Portugal. Models are solved with VISUAL BALAN v2.0, a code which performs daily water balances in the root zone, the unsaturated zone and the aquifer and requires a small number of parameters. A lumped hydrological model failsto fit measured stream flows. Its limitations are overcome by considering the dependence of the temperature and precipitation data with elevation and the spatial variability in hydrogeomorphological variables with nine sub-basins of uniform parameters. Model parameters are calibrated by fitting stream flow measurements in the Zezere river. Computed stream flows are highly sensitive to soil thickness, whereas computed groundwater recharge is most sensitive to the interflow and percolation recession coefficients. Interflow is the main component of total runoff, ranging from 41 to 55% of annual precipitation. High interflows are favored by the steep relief of the basin, by the presence of a high permeability soil overlying the fractured low permeability granitic bedrock and by the extensive subhorizontal fracturing at shallow depths. Mean annual groundwater recharge ranges from 11 to 15% of annual precipitation. It has a significant uncertainty due to uncertainties in soil parameters. This methodology proves to be useful to handle the research difficulties regarding a complex mountain basin in a context of data scarcity.
- Granite geomorphology and its geological controls, Serra da Estrela, PortugalPublication . Migon, Piotr; Vieira, GoncaloSerra da Estrela is an elevated granite massif in central Portugal, characterized by extensive plateau surfaces incised by deep valleys affected by Quaternary glaciation, bounded by steep fault-generated escarpments. The presence of seven major textural variants of granite provides an opportunity to study the relationships between lithology and relief, whereas DEM analysis helped to show the relationships between lithology and topography objectively. The higher ground is associated with fine- to medium-grained granites and is typified by planar surfaces of low gradient, with occasional angular tors and rock pedestals. Block fields built by angular material are common in the parts that were not previously glaciated. Less elevated parts of the plateau are supported by medium- to coarse-grained granites and show more varied topography, with an abundance of tors, boulder piles, and depressions. Lithological boundaries locally coincide with slope breaks but this is not the rule. In the northern part of the massif a deep topographic basin has evolved in biotite granite, whereas deeply incised valleys follow major fault lines. Geological controls show a hierarchy, in that gross relief reflects the pattern of tectonic uplift and subsidence, whereas lithology and then fracture patterns become more and more important if one focuses on smaller and smaller landforms.
- Tourism Charter of Serra da Estrela: a tool for planning and tourism promotionPublication . Castro, Emanuel; Fernandes, Gonçalo; Firmino, GiselaThe Tourism Charter of Serra da Estrela intends to be a management, promotion and revaluation tool of Serra da Estrela as a tourism destination and its products. It is therefore important to know the resources in its territorial context and how they are suitable for tourism, seeking to optimize and manage the potential impacts produced. The tourism phenomenon has an inductor character, able to promote territorial resources and contribute to the development of indigenous potential. It is an activity that is the driving force of development in many regional economies, when properly managed. By its nature, tourism is a complex phenomenon that integrates political, economic, social, cultural, biophysical, ecological and aesthetic subsystems, and its sustainability comes from the symbiosis between these different fields. At the same time, it is necessary to respond simultaneously to the expectations of visitors and the aspirations of local populations. In this context, this paper aims to describe the development of the Tourism Charter of Serra da Estrela, presenting a dynamic character through the application of geographic information methodologies which will be not only a tourist planning tool, but also an interactive platform to which tourists can access information.
- Aspiring Estrela Geopark: Estratégia Para a Valorização e Desenvolvimento do Território da Serra da EstrelaPublication . Fernandes, Gonçalo; Castro, EmanuelThe creation of geoparks is a new paradigm in the way how it disseminates Geosciences, the territories, heritage (tangible and intangible) and ways of life of their communities. The management strategy of a Geopark is not only the geological heritage as well as biodiversity, archeology and other aspects of cultural legacy. Thus geosciences gained public visibility and asset size. Geopark bet on the network of social responsibility, as well as the strategic partnerships that promote the strengthening of the territory, with regard to their quality of life, based on economic activities and supported in products and services with high added value trying to increase the levels of knowledge and income. The diversity of glacial marks, the richness of its heritage and character of its landscape make the Serra da Estrela a unique geography, which his structured approach will create a strong brand, with tourist potential and recognized heritage and cultural value.
