The common toad ( Bufo bufo ) is a widespread species in Europe, with accidental occurrence in caves. This study reports the first case of breeding of B. bufo in a natural cave in the Carpathian Mountains. The breeding activity was observed at the end of May and the beginning of June. We identified pairs of common toads in axillary amplexus, egg st...

In the Banat Plain were recorded more than half of the number of bird species in Romania. There are eleven Nature 2000 Bird Protection Sites (SPAs) and in all of them have been registered aquatic bird species. The water surface areas were greatly reduced since the starting of the hydro-technical works 300 years ago. Nowadays, the anthropic pressure...

Mapping of snow avalanche tracks based on topographic maps, airophotos and field data to achieve inventories for the whole mountainous areas in Romania is an important step in snow avalanche risk assessment and other related geomorphic processes. This requires experience and it is a time consuming process. In the absence of field data, the process...

The Satchinez Swamps, a remnant of the swamps once specific for Banat Plain, is an ornithological reserve since 1942 and the habitat of many protected bird species. Draining works conducted in the seventies affected the reserve by decreasing the water surface area. Thirty-five years later, hydro-technical works aiming to restore the former aquatic...

Snow avalanches are a common geomorphic process and natural hazard in the Southern Carpathians (Romanian Carpathians). The spatial distribution of avalanches is controlled by topographical factors, meteorological variables and human factors. This study examines the occurrence of avalanches in two glacial areas in the Făgăraş massif, Bâlea (on the n...

Geomorphological mapping is an important tool in geomorphology and related disciplines, yet it depends on the expertise and experience of the practitioner. The reliability of the technique and its products has not been subject to sufficient quantitative evaluation. In this study, we evaluated the magnitudes of differences in mapping glacial cirques...

The Seciuri settlement in Romania emerged and developed on a corrugated terrain, fragmented by numerous small valleys cut by sheet wash and the Amaradia springs. In the west, north and east, it neighbours two lignite quarries – Seciuri Vest and Seciuri-Ruget, lying at the contact between the Getic Piedmont and Getic Subcarpathians. In the spring of...

Grazing was the main activity of the inhabitants of the region, so that on an area of only 750 hectares, 16 sheepfolds existed simultaneously. In the last 20 years, mountain pastures were gradually abandoned a fact which led to some changes in land cover, mainly close to timberline. The aim of this paper is to identify general trend of land cover c...

The barren karst areas are not typically for the karst regions of the morphoclimatic system of temperate zone. Nevertheless the importance of assessing the extension and degree of compactness of bare karst is grounded by the fact that these areas represent both particular geomorphological landscape, with specific implications in the karstic process...

The geomorphological mapping is a difficult and time-consuming task, but the geomorphological maps are necessary tools in many practical activities. The conversion of the already done analogue geomorphological maps into digital form could be a useful alternative. The result of this conversion process presents some errors which are observed during t...

Based on a case study, this paper aims to be the first attempt, in the Romanian geography, to analyze the snow avalanche potential in one of the most representative glacial areas from the Fagaras Massif (Southern Carpathians - Romanian Carpathians), respectively Balea glacial area, located on the northern slope of the Fagaras massif, in the central...

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 structur...

Geomorphologic mapping is an important fact in many research studies and the traditional methods are time consuming and expensive. This paper aims to develop a semi-automated rule-based method for the detection of glacial cirques for a test area located in the Ţarcu Mountains (Southern Carpathians) in an object-oriented approach. In this study we h...

The identification of intrinsic bonds between the men and the geographic space where they lived is one of the desiderata that any archaeologist tries to reach through systemic analysis of an archaeological site reported to the environment. Modern Archaeology uses work methods and techniques borrowed from Geography, which, both for Prehistory and fo...

The study areas are located in the western part of Romania, in the historic region Banat, with a relatively varied relief formed of low fields, high fields, piedmonts and hills. The identification of areas with a high probability of new archaeological sites was done through the GIS modeling using complex data sources. The first step was to establis...

Presently, the development of GIS together with the analysis of the digital terrain model (DTM) and the satellite imagery makes possible the improvement and the up-dating of the geomorphological maps content. A geomorphological map synthesizes the way the relief forms, the way surface or sub-surface deposits are distributed, as well as the processe...

Abstract: The paper presents a method for the semiautomated classification of the planation surfaces, using the Digital Terrain Model (DTM) and the objectoriented 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...

The archaeological site Cornesti “Iarcuri” is the largest earth fortification in Romania, made out of four concentric compounds, spreading over 1780 hectares. It is known since 1700, but it had only a few small attempts of systematic research, the fortress gained interest only after the publishing of some satellite images by Google Earth. It is loc...

This paper deals with some human geomorphological aspects concerning the impact in the alpine area of the Southern Carpathians (Transylvanian Alps). After field investigations and taking into account the major effects of road building, military and mining activities, pasture and tourism activities in the geomorphological landscape we have the possi...

The southwestern region of Dacia was one of the most intensively colonized territories of Ancient Rome, with which it maintained economic relations for centuries. These long-term relationships, and the Romanization of this territory, are best seen in the analysis of the coarse ware pottery. In this paper, we discuss our work to compile a typologica...

The present study analyses the physical - geographical as well as the anthropical factors responsible for the extension of the alpine level in the Făgăraş Mountains. We carried out a comparison of the present situation with the theoretical area of extension of the alpine domain. The lower limit of the alpine level corresponds to the upper timberlin...

The present paper analyses the changes of the natural and antrophic frame produced in the last 40 years within the Ornithological Reservation “The Bogs of Satchinez”. The analysis was carried out by using black – white orthophotoplans (from 1963) at the scale of 1: 10000, and, in order to obtain the present maps, air photos at the scale of 1: 450 t...

L’extremité de l’ouest des Carpates Méridionales, connue comme la Groupe Retezat-Godeanu (qui compris aussi Les Monts Mehedinţi) est l’une de plus intéressante région carpatique tant du point de vue évolutif que du point de vue géomorphologique. Ce fait est soutenu par la présence simultanée-seulement dans cette région-des trois unités tectoniques,...

Gis and geomorphology (I). Digital Terrain Model generation and some morphometric analysis. Using of GIS in geomorphology is based on the digital terrain model (DTM) analysis. At present, the most powerful method of representing relief is to construct a mathematical model of the earth's surface: a digital terrain model (DTM) or digital ellevation m...

The study was done in the Southern Carpathians which are also called the Transylvanian Alps, the most representative mountain unit of the Romanian Carpathians. Southern Carpathians have a central position in Romania with a general east-west orientation and a total surface of 14 040 km 2 . Southern Carpathians have a high massivity and maximum altit...
