“…The Sand/Silt unit consists of flood plain sediments ( sensu Allen, ; Bridge, ) and represents a later phase of accretion of the fan at its distal margin (Cremaschi & Nicosia, ). Sandy layers are interpreted as related to fluvial channel deposits (levee and crevasse splay sedimentary facies), whereas silty and clayey sediments represent distal overbank sedimentation within the flood basin.…”

“…It consists of medium textured gravel, often in a sandy matrix, and represents the main body of the fan. A direct dating is not available for this unit, but on the basis of the regional geological context (Cremaschi, 1987;Cremaschi & Nicosia, 2012), we propose that the Gravel unit was deposited during the Late Pleistocene to the early Holocene. At its top is the Sand/Silt unit that was observed not only in cores, but also directly exposed in the construction site in the area of Santa Maria Nuova Hospital (Fig.…”

On the grounds of geomorphological evidence, core stratigraphy, and archaeological and historical sources, the relationships between the urban development of Reggio Emilia (Po River plain, Northern Italy) and the adjoining Crostolo River are reconstructed over the last two millennia. The town of Reggio Emilia was established in the second century B.C. along the Crostolo River, but geographic relationships between river and town changed several times because of the collective effects of human activity, geological processes, and climatic change.

Assessing visibility and geomorphological biases in regional field surveys: The case of Roman Aesernia

et al. 2017

Archaeological field survey data can be biased by many factors, such as ground visibility conditions (e.g. vegetation, plowing) and geomorphological processes (erosion, deposition). Both visibility and geomorphological factors need, therefore, to be assessed when patterns of settlement and location preferences are inferred from survey data. Although both factors have been taken into account in a variety of fieldwork projects and studies, their combined effects remain hard to predict. In this paper, we aim to address this issue by presenting a visualization method that helps in evaluating in combination the possible visibility and geomorphological effects in regional, site-oriented field surveys. Capitalizing on first-hand data on both archaeology and soil types produced by the recent Leiden University field survey project in the area of Isernia (Roman Aesernia, Central-Southern Italy), we propose a combined application of statistical tests and geopedological analysis to assess the extent and scale of the main biases possibly affecting the interpretation of the ancient settlement organization. Translating both sets of biases into GIS maps, we indicate the likelihood that negative field survey observations (absence of sites), in specific parts of the landscape, are genuine or rather distorted by biasing factors. The resulting "archaeological detectability" maps allow researchers to formally highlight critical surveyed zones where the recording of evidence is likely unreliable, and thus provide a filter through which archaeologists can calibrate their interpretations of field survey datasets.
