The Marchiazza is formed in the eastern and hilly part of the Alpi Biellesi from the confluence of several streams; the longest of them is named Rio della Moja and has its source on the southern slopse of Cima Frascheja. The Marchiazza flows close to the village of Lozzolo and comes out of the hills entering the Po plain. In the territory of Gattinara it receives the waters of its mail natural tributary named Rio della Marchiazzola. Heading south in crosses the Baraggia heathland and then the paddy fields of the province of Vercelli. Between Albano Vercellese and Villarboit the Marchiazza is overpassed by Canale Cavour through a water bridge.
