The territory of the comune of Rovasenda is enclosed in the alta pianura vercellese (high plain of Vercelli, also known as Baraggia). The land is levelled, with a slight inclination from north to the south. Its altitude varies from 259 to 199 m above sea level.; the Comune is about 9 km from north to south and 5 km from east to west. It borders
Roasio e
Gattinara to the north,
Lenta,
Ghislarengo e
Arborio to the east,
San Giacomo Vercellese and
Buronzo to the south and
Masserano and
Brusnengo to the west, which form part of the
province of Biella. The comune's territory comprises the
Rovasenda stream as well as the
Marchiazza stream, which marks part of its eastern boundary. Numerous irrigation canals supply the surrounding rice paddies with water; among these, the Roggia del Marchese (also known as
Roggia Marchionale) is the most noteworthy.Most of the settlements are found within the main administrative division (
capoluogo), surrounded by vast rice fields speckled with sparse, secluded farmhouses; aside from the capoluogo, there are no divisions of relevant size.Rovasenda is located at the crossroads of two railway lines, the
Santhià-Arona railway and the
Biella-Novara railway; oddly enough the town has two separate yet adjacent railway stations (the
Rovasenda and
Rovasenda Alta railway stations, on the
Biella-Novara and the
Santhià-Arona railway lines, respectively). == Demographic evolution ==
