It is a right-bank tributary of the [[Po (river)|Po River]]. The stream rises in the [[Apennine Mountains]] near [[Monte Penice]] and flows in a northerly direction into the Po.
==Geography== The Tidone's sources are on the northern slope of [[Monte Penice]] at an altitude of over {{convert|1000|m|ft|0}} in the [[Apennine Mountains]] in the municipality of [[Menconico]]. The river flows down a narrow mountain valley called ''Val Tidone''. The upper reaches of the stream are located in the [[Province of Pavia]] while the middle and lower course is in the [[Province of Piacenza]]. The village of [[Romagnese]] is found in the upper part of the valley.
Near the town of [[Nibbiano]] the Tidone flows into the [[Lago di Trebecco]] which is formed by a dam built in the 1920s. The reservoir is used for irrigation and the dam produces a modest amount of electricity.
The Tidone leaves the foothills near [[Pianello Val Tidone]] and enters the flat Po plains. The stream flows into the Po west of [[Piacenza]] between the towns of [[Sarmato]] on the west and [[Rottofreno]] on the east. The affluents of the Tidone are mountain streams called the Morcione, Tidoncello, Chiarone and Luretta. The [[Trebbia]] River is the next major river to the east.
==History== The [[Battle of Trebbia]] was fought near the lower course of the Tidone when [[Hannibal]] defeated a [[Roman Republic|Roman]] army in 218 BC. The name dates from the battle when a Roman [[centurion]] found the Tidone's waters to be clear and drinkable while the nearby Trebbia supposedly ran red with the blood of the battle's victims. In thanks to the river, the officer said ''O Valle ti dono questo anello; ti dono'' (I give). Also fought in the area was a second [[Battle of Trebbia (1799)|Battle of Trebbia]] in 1799 which pitted a [[First French Republic|Republican French]] army against [[Alexander Suvorov]]'s allied armies of the [[Russian Empire]] and [[Austrian monarchy|Habsburg Austria]].
