In Roman times a maritime line was created that linked the lake, thanks to Ticino , to Pavia , from where the ships would then continue along the Po to the Adriatic Sea . After the fall of the Western Roman Empire , the lake was under different domains. Most of

During winter, the lake helps to maintain a higher temperature in the surrounding region (since water releases heat energy more slowly than air). The temperatures are cooled down in summer by the breezes that blow on the water's surface, changing its colour. The area enjoys nearly 2300 hours of sunshine a year and an average annual temperature of 15.5 °C (60 °F). The water of

Its form is very sinuous so that there are few points from which any considerable part of its surface can be seen at a single glance. If this lessens the effect of the apparent size, it increases the variety of its scenery. While the upper end is completely alpine in character, the middle region lies between hills of gentler form, and

The causes are first a decrease in the sedimentation rate due to the locking of sediment behind hydroelectric dams and the deliberate excavation of sand from rivers for industrial purposes. Second, agricultural use of the river is heavy; during peak consumption

The main products of the farms around the river are cereals including – unusually for Europe – rice , which requires heavy irrigation . The latter method is the chief consumer of surface water, while industrial and human consumption use underground water. The Po has 141 tributaries . They include (R on

The rate of coastal zone progradation between 1000 BC and 1200 AD was 4 m/yr. Human factors, however, brought about a change in the equilibrium in the mid-20th century with the result that the entire coastline of the northern Adriatic

The diversion channel was at first called the Po di Ficarolo . The Fiume Po before then followed
