Vorma was so named because it was a "warm" river that never freezes over, while both the Glomma and the
Gudbrandsdalslågen routinely freeze. The junction of the Vorma with the Glomma at Årnes and
Nes is the site of the Funnefoss on the Glomma, a fall.
History
The junction of the Minnesund and the Vorma, Eidsvoll, served as an ancient 'ting' place - or meeting place for the local council or parliament - for
Romerike during the period when travel by boat was much easier than by land. The "Eidsivating" was, according to tradition, founded by
Halvdan Svarte, and served as the 'ting' place for all of the
Opplands and
Viken. Saint Olav also held a ting there and built a church at this site in 1017.
In 1795 a landslide totally blocked the Vorma at
Disen for 111 days, completely drying the riverbed. A channel was cut around it to prevent a major overflow, with accompanying downstream damage.

, lies the Svanfoss where the water level in Lake Mjøsa is regulated. A lock, which bypassed the Svanfoss, lifting boats to allow the bypassing of the fall, opened in 1906.
Geology
The Vorma discharges from Lake Mjøsa at the village of Minnesund on the southern lakeshore. The southern shore of Lake Mjøsa is a
terminal moraine deposit formed by a pause in the glacial ice retreat (the Minnesund pause) that occurred ~9,400 years before the present. The terminal moraine is characterized by substantial clay, sand and gravel deposits. The Vorma has eroded through these deposits, leaving steep banks with many high gradient tributaries forming cascades as they join the Vorma. The river cut down until it met the less-easily eroded intrusive sill (part of the Oslo Graben) at the town center of Eidsvoll where it formed the
Svanfoss. Falls are also found where the Vorma meets the Glomma - the
Funnefoss.
