<p>Geomorphological mapping in urban areas must address the wide distribution of anthropic landforms and deposits in addition to the natural landforms and deposits. Consequently, an integrated scientific approach, by combining field surveys and subsoil data with the use of historical documents, is necessary to recognize the main anthropic modifications of the natural landscape over time.</p> <p>Recent field research concerning the morphology and subsoil stratigraphy of Turin, especially through the study of several boreholes, has led to the recognition of various anthropic modifications of the Turin natural landscape and shallow subsoil stratigraphy that have occurred in the last four centuries. Moreover, the examination of ancient papers and historical maps, with reported sectors in which the morphology of Turin appears different from the current one, indicated some evident, partly anthropic, modifications.</p> <p>Anthropic changes deduced essentially from ancient topographic maps have been related to the trend of riverbeds, such as the stabilisation of the Sangone R. meander near the Miraflores Castle, the setting and deletion of the Nichelino meander, the shift of the Sangone-Po rivers confluence and the deletion of the wide meanders of the Dora Riparia R. near its confluence with the Po R., to allow the expansion of the monumental cemetery. Other significant anthropic river modifications that have been difficult to identify concern the filling of several ancient tributary incisions on the left of the Po R., which have now completely disappeared.</p> <p>Anthropic modifications deduced essentially from field surveys regard wide sectors of southern Turin, Rivalta and Beinasco, which consisted of ancient clay quarries, associated with several brick-kilns, in which the surface was lowered through the removal of the clayey silt overbank cover of the Turin Unit. </p> <p>Areas in which the landfill has substantial thickness and extension such as to simulate natural river terraces were also recognized, evidenced by the observations of borehole cores coupled with the radiocarbon dating of the underlying fluvial deposits, such as the long stretch between the Palazzo del Lavoro and the Balbis Bridge.</p> <p>Surface surveys alone are sufficient to recognize the areas involved by substantial anthropic interventions when they are characterized by hummocky morphology such as in the Valentino Park and the Cavour Garden. Finally, anthropic modifications deduced essentially from historical reports consist of as the construction and filling of the Michelotti Channel along the right riverside and the use of the Po banks and sand of the Vallere Unit by bathing establishments.</p> <p>The progressive building of Turin was closely related to the natural evolution caused by geomorphic agents (above all erosional and/or depositional processes carried out by watercourses) but also by anthropic modifications of the topographic surface (excavations and/or fillings). The investigated anthropic modifications of the Turin landscape are therefore useful to both the scientific approach and the use of urban subsoil for application purposes.</p>

<p>Proglacial lakes are complex environments that can unravel the sedimentary dynamics of glacier, giving a crucial insight during the deglaciation phases. In this optic, the interplay between proximal and distal glaciolacustrine facies is a fundamental record of paleoenvironmental, paleoglaciological and paleoclimate changes that occurred to glacier and its surrounding landscape. Situated at the Southern Alps foothill (Northern Italy), the Adige River Glacial Amphitheatre, surrounding the Rivoli Veronese town, contains glaciolacustrine sediments in its innermost moraine ridges. This glacial amphitheatre formed during the Last Glacial Maximum (LGM), when it shaped the outermost ridges related to maximum advances, and subsequent retreats modelling the inner moraine ridges. In the innermost one, the outcrops were described and recognized as glacial diamictons, fluvioglacial gravels and glaciolacustrine heterolithic deposits. The focus on the glaciolacustrine sediments permitted to disentangle between the coarser sediments, such as sand and gravelly sand, are attributed to the proximal facies, while sandy silt, silty clay and silt are interpreted as distal facies. The study of the distribution of proglacial deposits shows a complex evolution of the lacustrine system during the deglaciation stages. In fact, two time-distinct glaciolacustrine phases are recorded in the investigated area: the former is linked to a glacial pulsation preceding the last phase of LGM or all LGM phases, while the latter related to the LGM final recessional glacial step. The ice-marginal proglacial lake, relative to the last phase of LGM, can be further separated in two spatial different systems (respectively northern and southern); this distinction is based on different facies associations and patterns that are recognized in the two studied portions. In the final step, the two lakes coalesced together, and probably a glacial lake outburst flood happened, emptying the proglacial lake and leaving evidence in the Venetian Plain, South of the Adige River Glacial Amphitheatre. The comprehension of the deglaciation of the lower Adige Valley helps to reconstruct the transition between LGM and Post-Glacial period in the Southern Alpine region.</p>

<p>A late-glacial / early-Holocene lacustrine and peat succession, with conifer macro-remains and including some palaeo-mesolithic flint artefacts, was investigated in several steps in the Palughetto intermorainic basin (Venetian Pre-Alps). Published data on the geomorphic and stratigraphic relations, 14C chronology, pollen series and archaeology allow a reconstruction of the environmental history of the basin and provide significant insights into the reforestation and human peopling of the Pre-Alps. In this dendrochronological study, we analysed 203 trunks and branches from the subfossil forest of Palughetto mire, resulting in seven groups of 34 trees, which fall in a period of 1600 years of the Bølling-Allerød Interstadial between c. 14,900-12,800 cal BP. Crossdating was facilitated by numerous decadal AMS <sup>14</sup>C age determinations. Most of the trees were not found ‘in situ’. They fell into the lake and were preserved in the sediment. The forest mainly consisted of the species spruce (<em>Picea abies</em> Karst.), larch (<em>Larix decidua</em> Mill.), birch (<em>Betula pubescens</em> Erh.), poplar (<em>Populus spec.</em>) and willow (<em>Salix spec.</em>), confirming results from palynology and botanical remains analyses. Growth rates are different for each species. Spruce trees show wide rings and ‘complacent’ tree growth. Larch tree rings were smaller with higher interannual variability. The high growth rate of spruce indicates favourable growing conditions such as moderate temperatures and sufficient water supply during the vegetation period of the Bølling-Allerød in Palughetto, which is similar to the modern situation of the area.</p>
