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.

Abstract: Landslide risk management represent the final steps within a long process of evaluation that starts with detailed field observation. Based on geomorphological field mapping and the additional support offered by other methods and devices (aerial photos or remote sensing images, GPS and total station surveys, statistical analysis, numerical modelling etc.), landslide susceptibility and hazard assessments offers compulsory information for risk mapping. Unfortunately, there are still papers and even legislative initiatives which skip these important steps, offering results which can be at least severely arguable. The present paper is focusing on highlighting a proper methodology for landslide risk management, having as a case-study a small catchment typical for the Romanian Curvature Carpathians-Subcarpathians contact (Muscel Valley). Within this space of 19.6 km2, the risk management assessment started with detailed geomorphological mapping, providing information for landslide inventory. Based on this inventory, statistical analysis allowed the susceptibility assessment, and through additional information like landslide frequency and magnitude, triggering threshold and its recurrence interval, landslide hazard assessment and mapping were performed. Finally, risk analysis, assessment and management, outlined by a risk map, finished the procedure, aiming to provide useful information for risk governance.

Abstract: Riverbed sediments morphometrical analysis can offer, along granulometric and petrographic analysis, relevant information on sediment source origin, transport environment and sedimentation process. Today, there are numerous descriptive indices for clasts shape and size, each one trying to evidence the influence of dynamic conditions and clasts petrography that are mobilized in certain transport environment, their shape at certain moments. Among these, this analysis focused on only 10 morphometric indices. The obtained data, either from direct measurements on 5,027 clasts or after index calculations, were processed and obtained a set of statistical parameter (average, median, standard deviation, etc.). Based on these data was assessed „optimal shape” for Trotuş riverbed gravels. Some parameters (like average value) were used to create frequency histograms for some morphometrical indices in sampling points and to make some mathematical modeling.

Abstract: In the present study there were analyzed two sectors of river bed, located along the lower course of the Buzau River: Vadu Paşii – Săgeata (sector of braided channel) and Ibrianu – Custura. Through the calculation of some indices (the braiding index, the sinuosity index), the performance of correlations between elements established through measurements (length and amplitude of the meanders, the width of the river bed) could be differentiated the types of river beds. By analyzing the Austrian maps in 1910, of the topographic maps, orthophotoplans and Landsat images from 1987, 2000, 2006 and 2007 it could be observed the spatial dynamics of the specific element of each type of river bed. For the Vadu Paşii – Săgeata sector the braiding index reduced from 3.4 in 1981 to 2.32 in 2005. In the Ibrianu –Custura sector, there took place many underpinnings at the level of the complex meanders, and the length of the river reduced from 36.4 km to 24.5 km.

Abstract: This paper aims to analyze the correlations between the tectonic, structural and lithological elements in the Cricovul Dulce river Basin and their reflection in the landscape morphology. The Cricovul Dulce river basin’s position in the Curvature Subcarpathians and Cricovul piedmont plain led to different structural and lithological characteristics which favored a certain type of geomorphological landscape evolution in accordance with the physical-geographical particularities. The faults (Câmpina, Colibaşi), the Vârfuri- Vişinesti- Draganeasa dislocation line, and the presence of anticlines (Siliştea Dealului, Gura Ocniţei- Moreni, Babanucului) and of synclines (Malurile- Valea Lungă, Ruda) in the Cricovul Dulce Basin, influence the dynamics in the morphographical development of the entire region. The lithology, the clastic rocks (sands, marls, clays, gravels), unconsolidated sometimes, and the layers with different hardness, increase the morphodinamic processes and give rise to a structural relief specific to the Subcarpathians regions. The valleys adapt to the structure and thus, there are different types of steams: subsequent, obsequent and consequent. The geology gets even more complicated due to the presence of some coal layers (the perimeter of Filipesti de Padure) and salt massifs (Moreni, Colibasi) in the basin. The relief of the Cricovul Dulce Basin reflects the lithological composition and structure of the region over which overlaps, resulting from this point of view a diversity of landscapesPoziția Bazinului Cricovul Dulce în Subcarpații de Curbură și în Câmpia piemontană a Cricovului a determinat caracteristici litologice și structurale diverse, fapt ce a favorizat un anumit tip de evoluție a peisajului geomorfologic in concordanță cu particularitățile fizico-geografice.Faliile (Câmpina, Colibași), linia de dislocație Vârfuri-Vișinesti-Drăgăneasa, precum și prezența anticlinalelor (Siliștea Dealului, Gura Ocniței-Moreni, Babanucului) și a sinclinalelor (Malurile-Valea Lungă, Ruda) în Bazinul Cricovului Dulce, influențeaza dinamica în evoluția morfografică a întregii regiuni.Litologia, rocile moi (nisipuri, marne, argile, pietrisuri) uneori neconsolidate, precum și straturile cu durități diferite intensifică procesele morfodinamice și dau naștere unor reliefuri structural specific regiunilor subcarpatice.Văile se adaptează la structura și avem astfel văi de tip: subsecvent, obsecvent și consecvent.Geologia se complică și mai mult datorită prezenței în Bazin a unor strate de cărbuni (perimetrul Filipești de Pădure) precum și datorită prezenței masivelor de sare (Moreni, Colibași). Relieful Bazinului Cricovului Dulce reflectă alcătuirea și structura litologică a regiunii peste care se suprapune, rezultând din acest punct de vedere o diversitate a peisajelor.
