Idrography
The province of Pavia is a territory rich in water resources, very
important for its economy and its history. Rivers constitute a fundamental
irriguos system for the richness of the pavese agriculture, through
an intense network of canals. The main rivers are the Po and the Ticino.
Other minor rivers are Olona, Vernavola, Gravellona, Navigliaccio,
Staffora and Agogna.
The Po is the major Italian river for its length (653 km) and its
basin (74.970 km2). The Po raises on Monviso and it flows towards
Adriatico sea after crossing the whole Pianura Padana.
The Ticino is called the bluer river of Italy due to the limpidity
of its water. It raises in Switzerland from San Gottardo mountain.
Its length touches 248 kms and it's the left affluent of the river
Po, in which it joins it in Vaccarizza (Ponte della Becca) just out
Pavia .

Orography
The hill areas correspond to the 16,2% of the territory of
Pavia province. In particular the Oltrepò Pavese is a territory
with a significant presence of hills constituted by sedimentary marine
rocks with a relevant clayey component. This area presents a complex
orography, with primary, secondary and inferior valleys. In the border
with the province of Piacenza, there is the Valle Versa, dedicated
to the vine cultivation. The "Central Oltrepò" is
constituted by a number of valleys fan-shaped, and bends toward west
compared to the Valle Versa axis, the Ronchi valley, Losana valley,
and others of minor connotation, until the limit of Ghiaia di Montalto
valley.
This last part of the Oltrepò is bordered by the Staffora valley
that climbs the hills of Varzi, Santa Margherita Staffora which also
has minor valleys as the Val di Nizza.
