“…Published materials and archaeological deposits apparently were not very disturbed further encouraged us to select it for our investigations. At the same time, the high degradation of the site strongly affected by natural (mass movement, erosion) and anthropogenic disturbances [20][21][22][23] (Figure 2A,B) provided the main incentive for choosing it as our case study. Războieni-Dealul Mare/Dealul Boghiu was first investigated in 1930s through trial pits by Tafrali, O., Manoliu, V. and Condurache, E. who mention that "pieces from the collapsed walls of the dwellings" [25] were found less than half a meter from the surface.…”

This paper presents recent results of an integrated non-invasive investigation carried out in a previously unexplored settlement from northeastern Romania, belonging to the last great Eneolithic civilisation of Old Europe, the Cucuteni-Trypillia cultural complex. Although there is a long history of research concerning this culture, at only a handful of sites has archaeological research completed a comprehensive planimetric image. This makes it impossible to determine a typological evolution of the internal organisation of Cucutenian sites, both diachronically, across the three great phases of the culture (A, A−B and B for the Romanian area), and spatially, from SE Transylvania to the Republic of Moldova, and towards the steppes of the Ukraine. Accordingly, in certain environmental conditions, many essential behavioural aspects of Cucutenian communities are far from understood. Consequently, the generalisation and integration of non-invasive prospecting methods-Light Detection and Ranging (LiDAR), aerial photography, earth resistivity, magnetometry, and their integration through Geographic Information System (GIS)-clearly represents a feasible alternative for deciphering the Cucuteni culture. These complementary investigation methods were applied for this case study, emphasis being put on the conjoint use of datasets from each technique. On the basis of results recently obtained from the Rȃzboieni-Dealul Mare/Dealul Boghiu site, innovative characteristics are described concerning intra-site spatial organisation, a typology of the fortification systems, the existence of ritual or delimitation ditches, and the presence of habitations outside fortified areas.

“…High and very high susceptible areas will be correlated to the negative effects on the cultural heritage of the area (107 Neolithic sites). At an international level, there is a limited number of studies that tackle this issue [31,33]. This study comes as a necessity in an area with a very high potential to soil erosion and Over the last few years, statistical modelling for gully erosion has encountered an upward trend; whether employing one or more statistical models to determine gully erosion susceptibility, many authors are evaluating gully erosion susceptibility based on some local environmental factors and the weights derived from each method: the information value (IV) method [22], logistic regression [23], multivariate adaptive regression splines (MARS) [24], weights of evidence (WOE); frequency ratio (FR) [25], and index of entropy (IOE) [8].…”

Is Overgrazing Really Influencing Soil Erosion?

Soil erosion is a serious problem spread over a variety of climatic areas around the world. The main purpose of this paper is to produce gully erosion susceptibility maps using different statistical models, such as frequency ratio (FR) and information value (IV), in a catchment from the northeastern part of Romania, covering a surface of 550 km 2 . In order to do so, a total number of 677 gullies were identified and randomly divided into training (80%) and validation (20%) datasets. In total, 10 conditioning factors were used to assess the gully susceptibility index (GSI); namely, elevation, precipitations, slope angle, curvature, lithology, drainage density, topographic wetness index, landforms, aspect, and distance from rivers. As a novelty, overgrazing was added as a conditioning factor. The final GSI maps were classified into four susceptibility classes: low, medium, high, and very high. In order to evaluate the two models prediction rate, the AUC (area under the curve) method was used. It has been observed that adding overgrazing as a contributing factor in calculating GSI does not considerably change the final output. Better predictability (0.87) and success rate (0.89) curves were obtained with the IV method, which proved to be more robust, unlike FR method, with 0.79 value for both predictability and success rate curves. When using sheepfolds, the value decreases by 0.01 in the case of the FR method, and by 0.02 in the case of the success rate curve for the IV method. However, this does not prove the fact that overgrazing is not influencing or accelerating soil erosion. A multi-temporal analysis of soil erosion is needed; this represents a future working hypothesis.

“…TLS is fast becoming a standard technique for quantifying high resolution morphological change in a range of geomorphological settings (Schürch et al, 2011;Brasington et al, 2012;Grayson et al, 2012), as well as being increasingly used for monitoring the condition of upstanding structural remains (Hinzen et al, 2013). However, prior to this paper, the use of repeat TLS for monitoring archaeological sites is very limited and has been restricted to coarse (biannual / annual) temporal intervals (Romanescu et al, 2012;Romanescu and Nicu, 2014). The potential of terrestrial laser scanning to inform understanding of high temporal resolution changes on archaeological sites still therefore remains to be demonstrated.…”

AbstractEffective heritage management is reliant on an understanding of the range of current and potential future threats facing archaeological sites. Despite this, the processes leading to the loss of in situ archaeological remains are still poorly understood, including the rates, timing and drivers of surface erosion. This issue is particularly significant for abandoned historical metal mines in upland landscapes, where erosion rates are typically higher due to a combination of the unstable character of the archaeological deposits and the increased effectiveness of surface erosion processes. This study utilises repeat terrestrial laser scanning (TLS) to monitor the changing condition of two adjacent lead mines in the North Pennines, UK, over an 18 month period. The high spatial and temporal resolution of the TLS data, in conjunction with land cover characteristics derived from an unmanned aerial vehicle (UAV) survey, allows the detailed quantification of the causes and impacts of surface change.The results demonstrate that stream bank erosion is the process responsible for the most widespread and archaeologically significant damage, although localised gullying of mine waste heaps resulted in the largest volumetric loss of material (>160 m 3 ). Temporal variation in the erosion of upland archaeological sites is highly episodic, being dominated (>70%) by high magnitude but low frequency storm events. These results provide invaluable information regarding the causes and impacts of erosion of upland archaeological remains, as well as establishing a proven methodology which can now be applied to archaeological sites in other landscape contexts.
