Torrentiality – Morphohydrographical conditions in the Sebeş Basin (The Parâng Mountains Group, Southern Carpathians)

Abstract: This paper presents the morpho-hydrographical characteristics that define the torrential system inside the Sebeş basin (the Parâng Mountains). The manifestation of torrential erosion takes place on river basins of different sizes. In order to bring out the quantitative and qualitative differences in the stream discharge structure, we resorted to the determination of some geomorphometrical indices such as: the number of river segments, the frequency of elementary thalwegs, incipient or total torrentiality. The great density of the temporary valleys network, along with the emphasized slope of the ditches and flanks generate a high instability. The local differentiations of the geological sublayers and the complementarity of the use of the Cindrel, Lotru and Şureanu mountain areas generate its own answer forms on the aggressive action of the torrential rainfalls on elementary segments with temporary functionality, as well as on permanent hydrographic thoroughfares. The tributary streams received by the Sebeş River in the Carpathian sector have small hydrographic basins and they do not exceed rank 4 in the Horton-Strahler classification system. Torrentiality is stimulated by the combined effect of snowmelt and spring rains, but mostly by the aggressiveness of the torrential summer rains, which take over a modified geomorphological background through excessive depasturage, deforestation and hydropower harnessing. The streams and the floods, through the accumulation of high volumes and energies, produce slope damages, riverbed shifts, blockages and the destruction of communications infrastructure, and material loss.

Development of Tourism in the Transalpine Area. Premises and Possibilities

Abstract: The paper highlights the premises of the revitalization process of tourism: the significance of the “Transalpine” area, its intersection with routes of intense mobility of the population, the numerous natural and anthropogenic elements and their outstanding tourist value, the high rate of anthropization and insertions in the mountainous area caused by a diverse economy specific to mountainous areas, the tourist accessibility to the area, etc. The extremely favorable natural premises, the anthropogenic, ethnographic and enthno-folkloric potential, as well as the development of the north-south and east-west routes facilitate development of tourism in the Transalpine mountainous area. We have highlighted some distinct features of certain tourist models. Thus, there are two ethno-folkloric areas, two main tourist axes (a transversal one and a longitudinal one) and secondary tourist axes (along the mountains summits) as well as two urban areas (Sebeş in the north and Novaci in the south) which attract and guide the tourist flow. The purpose of this approach is aimed at diminishing the transit tourism, as well as diminishing seasonal tourism through the diversification of tourism. This requires coherent national development strategy integrated in the regional context, inter-county joint projects, the involvement of local authorities and tourist agencies as well as substantial funding.
