  • Piemonte Region Meteo-Hydrological Alert and Real-Time Flood Forecasting System D
    WMO/GWP Associated Programme on Flood Management ITALY: PIEMONTE REGION METEO-HYDROLOGICAL ALERT AND REAL-TIME FLOOD FORECASTING SYSTEM D. Rabuffetti, S. Barbero1 Abstract. Information is provided on the approach and experience in flood management in the Piemonte Region. Actual practices comprise mainly: (i) the structural mitigation of floods; and (ii) non-structural safety measures subdivided into land use planning and emergency plan activation through hydrometeorological forecasting and the development of an Alert System for flood forecasting and warning. Of particular interest is the comprehensive description of the hazard map developed to establish the interaction between human activities, river and hill slope dynamics, of the risk scenario identification as well as of the Information System for Operational Flood Forecasting 1. Location The Piedmont Region, located in the northwestern part of Italy, is a predominantly alpine region covering 25,000 km2. It is situated on the Padana plain and bordered on three sides by mountain chains covering 73% of its territory. The entire area drains to the Po River. The Upper Po River basin is characterized by a number of fast responding boulder-lined tributaries from the Alps (North and West) and Appenines (South). The mid Po River is moderately flat and contains wide floodplains and a meandering cobbled and sandy riverbed. The mountainous part of the territory is mainly natural and covered by forest and the pastures have been decreasing for the past decades. The lower areas are mainly used for agriculture and the land-use patterns have not changed significantly. The border between mountain and lowlands, as well as the major valleys, are more populated and industrially developed.

  • Alte Valli Pesio E Tanaro
    ALTE VALLI PESIO E TANARO IT1160057 SIC e ZPS ALTE VALLI PESIO E TANARO Comuni interessati: Briga Alta, Chiusa Pesio, Magliano Alpi, Ormea, Roccaforte Mondovì Superficie (ha): 11.278 Stato di protezione: Area protetta regionale (Parco naturale Alta Valle Pesio e Tanaro); protezione parziale. Legge Regionale 19 aprile 1979, n.18 Caratteristiche generali Il sito è collocato nelle Alpi Liguri al confine con Liguria e Francia, ed occupa una vasta area che comprende il Massiccio del Marguareis, la parte alta della Valle Pesio, il Vallone di Carnino e un ramo laterale dell’alta Val Tanaro. I confini dell’area, posta a quote comprese tra 850 e 2.651 m, seguono la linea di spartiacque della Val Ellero a ovest, e della Valle Vermenagna ad est, passando per la Cima del Cars (2.204 m), la Cima delle Saline (2.612 m), la P.ta Marguareis (2.651 m), la Conca delle Carsene (in media 2.300 m) e la Punta Mirauda (2.157 m). La morfologia di questa zona alpina risulta fortemente influenzata dalla predominanza di litologie calcareo-dolomitiche alle quote più elevate e, alle quote più basse, dalla presenza di rocce impermeabili di origine più antica (es. porfiroidi). Imponenti e di notevole impatto paesaggistico sono le forme del Massiccio del Marguareis, costituito da altopiani calcarei e dolomitici, ubicati ad una quota media di 2.000-2.200 m e separati dai fondivalle da ripide bastionate potenti anche 1.000 m, alla base delle quali risorgono le acque sotterranee, quando incontrano gli strati di rocce 466 IT1160057 impermeabili. Sono evidenti in queste aree sia le forme del carsismo ipogeo A sinistra, la cascata (grotte e inghiottitoi) che le forme del carsismo epigeo (doline e campi del Pis del Pesio.

  • Piedmont (Piemonte)
    Piedmont (Piemonte) growing occurs south of the Po Valley, in the provinces of Asti, Alessandria, and Cuneo. Within these provinces, the Monferrato and Langhe hills are planted with vineyards. Soils are predominantly calcareous marl and sandstone with varying percentages of clay and sand, Piedmont has a continental climate and the Alps to the north produce effect, In the Langhe and Monferrato hills, many of the best south facing vineyards planted with Nebbiolo are known as in the Piedmontese dialect,. Varietals Nebbiolo, is thin-skinned & produces wines of high acidity and tannin. The late-ripening Nebbiolo, together with Dolcetto and Barbera are the principal Piedmontese red grapes. Dolcetto, is the earliest to ripen and produces tannic, fruity wines, lower in acid and are suited to producing wines suitable for youthful consumption. Barbera is widely planted red grape. It has high acidity but low tannin. Other lesser indigenous red grapes of Piedmont include Brachetto, Grignolino, Ruchè, Croatina, Vespolina, and Freisa. varietal and is used in the production of the sparkling wines of Asti. Cortese, Arneis, Erbaluce and Favorita (Vermentino) are the other white grapes of the region,( in diminishing order of importance.) International grapes Cabernet Sauvignon, Chardonnay, Merlot, Syrah, Sauvignon Blanc, have been planted since the 1980s, although usage of such non-traditional grapes is limited to the less-specific DOCs and IGP wines. Piedmont has more DOC zones than any other wine region in Italy at the close of 2010, there were 16 DOCGs and over The most prestigious DOCGs in Piedmont are Barolo & Barbaresco, which are located along the Tanaro River, an area surrounded by the larger Langhe DOC.

  • Detecting Provenance Variations and Cooling Patterns Within the Western Alpine Orogen Through 40Ar/39Ar Geochronology on Detrita
    Geological Society of America Special Paper 378 2004 Detecting provenance variations and cooling patterns within the western Alpine orogen through 40Ar/ 39Ar geochronology on detrital sediments: The Tertiary Piedmont Basin, northwest Italy B. Carrapa* J. Wijbrans* G. Bertotti* Vrije Universiteit Amsterdam, Faculteit der Aardwetenschappen, De Boelelaan 1085, 1081HV Amsterdam, The Netherlands ABSTRACT The Tertiary Piedmont Basin is a synorogenic basin located on the internal side of the Western Alps. Because of its key position, the Tertiary Piedmont Basin represents an important record of processes occurring in the Alpine retrowedge for over the last 30 m.y. 40Ar/39Ar geochronology has been applied to detrital white micas as a prov- enance tool and to derive information on cooling and exhumation patterns within the surrounding orogen. The age distribution in the detritus shows that in the Oligocene the clastic sediments were fed mainly from a southern source area (Ligurian Alps) that widely records high pressure (HP) Alpine metamorphism (40–50 Ma) and, in part, Variscan metamorphism (ca. 320 Ma). From the Miocene, the main source area gradually moved from the south to a western Alpine provenance characterized by strong Late Cretaceous (70 Ma) and Early Cretaceous (120 Ma) signals. This enlarge- ment in the source is likely linked to an evolution of the main paleodrainage system into the basin. From the Serravallian, Variscan ages reappear; this is attributed to the exposure of the Argentera Massif as a new source for the Tertiary Piedmont Basin. The lack of thermal overprinting of the main detrital signals through time suggests that the western Alpine orogen has been regulated by episodic fast cooling and exhu- mation events followed by periods of slower erosion.

  • Marchesi Incisa Della Rocchetta Rocchetta Tanaro – Piemonte, Italy
    Marchesi Incisa della Rocchetta Rocchetta Tanaro – Piemonte, Italy Roero Arneis docg 2017 Arneis is a unique varietal indigenous to the Roero area, in Piedmont, north west of Alba. Since 2006, Roero Arneis has gained DOCG recognition, considered to be the highest quality ranking among Italian wines. Arneis is one of the most interesting wines from Piedmont, which can express an unrivaled fruitiness, a delicate freshness and mineral notes. Tasting notes Color: Straw yellow Nose: An adventure of fruit and floral. Middle notes of acacia, green apple, peach and apricot. Stone fruits and cantaloupe Taste: Light-medium bodied wine, smooth and crisp, fresh and persistent dry, savory and mineral Winemaking Process The grapes are destemmed, pressed and vinified in white, without maceration, and at a low temperature to preserve the original aromas of the varietal. The alcoholic fermentation takes place in stainless steel vats at controlled temperature. The wine is stabilized at a low temperature to prevent tartaric crystal precipitation in the bottle. Vineyards & Soil The area of production is the geographical area of Roero situated on the left bank of the river Tanaro, in this case the village of Corneliano d’Alba. On the dry sandstone soils of the Roero, the Arneis grapes acquire a delicate bouquet that is reminiscent of white flowers with fresh fruity hints ranging from apple to peach and hazelnuts. Average yield per vine: 1.2 kg (8,000 kg/Ha) Vineyard size: 4 ha Type of soil: dry sandy soil with calcareous stripes rich in mineral Time of harvest: beginning of September Average production: 27,000 bottles / 2,250 cases Analytical values Alcohol: 13.5% alc.

Not if you bring your hiking boots. Shoehorned between the rice-growing plains of Piedmont and the sparkling coastline of Liguria lie the brooding Maritime Alps – a small pocket of dramatically sculpted mountains that rise like stony-faced border guards along the frontier of Italy and France. Smaller, yet no less majestic than their alpine cousins to the north, the Maritimes are speckled with mirror-like lakes, foraging ibex, and a hybrid cultural heritage that is as much southern French as northern Italian. Despite their diminutive size, there’s a palpable wilderness feel to be found among these glowering peaks. Get out of the populated valleys and onto the imposing central massif and you’ll quickly be projected into a high-altitude Shangri-La. Whistling marmots scurry under rocky crags doused in mist above a well-marked network of mountain trails where the sight of another hiker – even in peak season – is about as rare as an empty piazza in Rome. This is Italy at its most serene and serendipitous. Not 20km to the south are the fancy resort towns of Portofino and San Remo; yet up here in the high country that straddles the invisible border between Italy and France all you need is a map, a decent pair of shoes, and enough cheese and ciabatta to keep you going until dinnertime.

  • Origin of Knickpoints in an Alpine Context Subject to Different Perturbing Factors, Stura Valley, Maritime Alps (North-Western Italy)
    geosciences Article Origin of Knickpoints in an Alpine Context Subject to Different Perturbing Factors, Stura Valley, Maritime Alps (North-Western Italy) Monica Marrucci 1, Gerold Zeilinger 2, Adriano Ribolini 1,* and Wolfgang Schwanghart 2 1 Department of Earth Sciences, University of Pisa, 56126 Pisa, Italy; [email protected] 2 Institute for Earth and Environmental Sciences, University of Potsdam, 14476 Potsdam, Germany; [email protected] (G.Z.); [email protected] (W.S.) * Correspondence: [email protected] or [email protected]; Tel.: +39-050-2215769 Received: 31 August 2018; Accepted: 15 November 2018; Published: 28 November 2018 Abstract: Natural catchments are likely to show the existence of knickpoints in their river networks. The origin and genesis of the knickpoints can be manifold, considering that the present morphology is the result of the interactions of different factors such as tectonic movements, quaternary glaciations, river captures, variable lithology, and base-level changes. We analyzed the longitudinal profiles of the river channels in the Stura di Demonte Valley (Maritime Alps) to identify the knickpoints of such an alpine setting and to characterize their origins. The distribution and the geometry of stream profiles were used to identify the possible causes of the changes in stream gradients and to define zones with genetically linked knickpoints. Knickpoints are key geomorphological features for reconstructing the evolution of fluvial dissected basins, when the different perturbing factors affecting the ideally graded fluvial system have been detected. This study shows that even in a regionally small area, perturbations of river profiles are caused by multiple factors. Thus, attributing (automatically)-extracted knickpoints solely to one factor, can potentially lead to incomplete interpretations of catchment evolution.
