Features of the Ski Area from the Romanian Banat

Abstract: The Romanian Banat is endowed with an important mountain area composed of the Banatului Mountains and the north-western part of the Retezeat-Godeanu Range, i.e. Ţarcu – Muntele Mic. The purpose of our paper is to make an account of the features of the two important ski areas within this mountain area: Ţarcu – Muntele Mic and Semenic. Their structure evolved over time according to the local and regional interest, but also due to more recent activities of the Romanian investors. Our research concluded that both ski domains have a great natural potential to sustain winter-sports and to further develop what today are two very small resorts. They have a low capability of attraction due to the small capacity of the pistes and to the fact that each resort has only two ski-lifts. In both cases the access is rather limited and as far as accommodation is concerned in both cases it is disproportional in relation with the provisioned capacity of the ski pistes. Having these aspects in view, we conclude that these resorts do not represent as yet a major attraction, especially due to the fact that there are undercapitalized and underdeveloped for the raising demand of the regional market for winter-sports. On the other hand in both cases projects have already been blue-printed by the aforementioned investors which are waiting to be undertaken for development.

The Use of the Digital Terrain Model in Analyzing the Natural Potential of the Muntele Mic – Poiana Mărului – Ţarcu Mountains Tourist Area to Extend and Plan the Ski Domain

Abstract: The present study aims at examining the natural potential of the region as a prerequisite for the planning and the expansion of the ski domain, in order to reinvigorate the resorts Muntele Mic and Poiana Mărului. The factors taken into account to identify the best areas for planning new ski tracks are: the altitude, the slope, the orientation of the slopes to the solar radiation, the duration and the thickness of the snow layer, the land use, the risk of snow avalanches occurrence and the degree of accessibility. Because the factors considered don’t have the same importance for the favorability, before the combination of the factors, we used the Analytical Hierarchy Process (AHP) implemented by the IDRISI Andes software to assign for each factor a relative weight to use in the analysis. The risk of snow avalanches occurrence was considered as restrictive factor (Boolean factor). The combination of factors by Weight of Evidence method resulted in the creation of the final model, which presents the probability map for new ski tracks. The probability degree varies continuously in space, from a very high probability (255) to a very low probability (0) depending on the combination mode in a certain area of the considered factors and their weight. We considered as optimal areas only the areas with values above 200. The best areas to expand the ski domain are the detached secondary peaks of Muntele Mic towards north and the northern slopes of the Nedeia Ridge. These areas could allow for the development of certain ski tracks at least the same size as the ones of the Prahova Valley. The development of the ski domain in these areas will connect the two resorts, Muntele Mic and Poiana Mărului, and could increase the touristic potential of the study area.

The Semiautomated Identification of the Planation Surfaces on the Basis of the Digital Terrain Model. Case Study: The Mehedinti Mountains (Southern Carpathians)

Abstract: The paper presents a method for the semiautomated classification of the planation surfaces, using the Digital Terrain Model (DTM) and the object-oriented analysis. The effort undergone for developing such a method has a number of motivations. The first one is that these landforms are very important for decoding the geomorphologic evolution of the relief units. The second motivation concerns the fact that their identification and mapping, by using classical means, represents a difficult demarche, which requires a lot of time. Finally, the already-known limits of the relief analysis using the DTM at pixel level impose the testing of an object-oriented analysis, in which the area under study is divided into objects of various dimensions, as homogenous as possible from the viewpoint of one or more properties. The method that we propose supposes the following steps: the realisation of the slope model and of the flow model, starting from the DTM; the division, by segmentation into objects that are as homogenous as possible from the viewpoint of the slope; the classification of the objects into landforms (planation surfaces) by using the fuzzy functions and taking into account more factors simultaneously (the average slope value, the minimum slope value, the flow coefficient and the altitude), and the selection and grouping of the identified surfaces into sculptural complexes. The first stages represent the automated part of the method, while the last one requires a detailed geomorphologic analysis of the area, as well as the validation of the results on the field. The method was firstly developed for the Godeanu Mountains, the map of the levelled surfaces (Niculescu, 1965) being used for the identification of the parameters included in the algorithm, as well as for testing the results obtained in the view of the improvement of the method. Due to the good results thus obtained, the same method was also used for mapping the levelled surfaces in the Mehedinţi Mountains, and, along with the field observations, there was realised the planation surfaces map for this relief unit.
