Geophysical Investigations within the Latus Dextrum of Porolissum Fort, Northwestern Romania—The Layout of a Roman Edifice
This paper summarizes the results of a recent geophysical investigation carried out at Porolissum, which is considered to be one of the most significant Roman sites in Romania. The geophysical survey was carried out within the latus dextrum of the fort, which is the same location that had been the subject of earlier geophysical surveys as well as older archaeological excavations (1970s) that had uncovered a multiroom building. A cesium vapor tota…
Late Pleistocene and Holocene aeolian activity in the Deliblato Sands, Serbia
The Deliblato Sands is among the largest uniform dune fields of Europe, with a very pronounced topography reflecting extensive past aeolian events. Although lacking numerical age data, previous researchers have hypothesized various periods of dune formation. Our research goals were to map the main morphological units of the Deliblato Sands, and to provide the first optically stimulated luminescence (OSL) ages for the major dune types. Mapping was…
Mapping the subsurface structures of a lost medieval village in South‐Western Romania by combining conventional geophysical methods
The medieval fortification of Mașloc, known as the ‘Șanțul Turcilor’ (Turkish ditch) is one of the best preserved archaeological sites in the Banat region, Romania. To reconstruct the subsurface archaeological features at the Mașloc site we combined three different geophysical methods: magnetometry, ground‐penetrating radar (GPR) and electrical resistivity tomography (ERT) and we used SfM (structure‐from‐motion) to achieve a detailed digital elev…
Recent morphodynamics of alpine lakes in Southern Carpathian Mountains using high-resolution optical imagery
Dendrogeomorphic reconstruction of past snow avalanche events in Bâlea glacial valley–Făgăraş massif (Southern Carpathians), Romanian Carpathians
Snow avalanche assessment in the S inaia ski area ( B ucegi M ountains, S outhern C arpathians) using the dendrogeomorphology method
In view of the damage and hazard they pose to human life and property, snow avalanches are a major natural hazard in the R omanian C arpathian M ountains. Despite the loss of life in recent years, geomorphological understanding of snow avalanches in R omania remains limited. The S inaia ski area, located in the B ucegi M ountains, is the most important ski resort in the R omanian C arpathians with two distinct centres of skiing activity: the V al…
