context_page_description: The Geography of Piedmont is that of a territory predominantly mountainous, 43.3%, but yes with extensive areas of hills which represent 30.3% of the territory, and of plains.
  To the north and to the west Piedmont is surrounded by the Alps, to the south by the Apennines, and to the east by the Po plain.
  To the west Piedmont borders with France, to the north with Valle d'Aosta and Switzerland, to the east with Lombardy and Emilia Romagna, and to the south with Liguria.
  Piedmont is the second largest of the 20 administrative regions of Italy, after Sicily. It is broadly contiguous with the upper part of the drainage basin of the Po which rises from the slopes of Monviso in the west of the region and is Italy’s largest river. The Po collects all the waters provided within the semicircle of mountains which surround the region on three sides.
  From the highest peaks the land slopes down to hilly areas, and then to the upper, and then the lower Pianura Padana. The boundary between the first and the second is characterised by risorgive, springs typical of the pianura padana which supply fresh water both to the rivers and to a dense network of irrigation canals.
context_section_description: The largest river in Piedmont is the Po.
  Other important rivers, in order of their mean rate of discharge, include:
