The river, whose name comes from Latin "Trebia",
is being born along the Prelà Mountain slopes at 800m
above sea-level, flowing for 118 Km maintaining a
The meandering watercourse, after a tortous run, little ponds
and bends, flows into the Po river, near Piacenza, even if
its spring is quite close to the Ligurian sea.
The regular shaped basin of the valley almost maintains a
The torrential regimes of the tributeries are quite changeable
during the year.
An important tributary is the Brugneto stream that flows
into the Trebbia river before Montebruno town, after having
filled up the homonym artificial lake.
Afterwards there is the Cassingheno stream near Due Ponti
town, and the Terenzone stream to the south of Gorreto that
flows down the slopes of the Carmo Mountain.
In the upper part of the valley on the right slope the limited
impluvium wideness prevents the formation of big basins,
even if there are numerous and steeply (Giassina stream,
Bocco stream, Cavagnaro stream...).
Streams of bigger length are formed only along the slopes
of Montarlone mountain because of the valley getting wider.
Some of these are the Sermigliasca stream, the Pescia
stream flowing between the Fontanigorda town and Casanova
town, and the Gramizzola stream, flowing down into the Trebbia
river close to Rocca dei Corvi and on the border between
Liguria and Emilia.
