Nera (Danube) Nera (Danube) The Nera (, or Нера, ) is a river running through Romania and Serbia. It is a left tributary of the Danube, which it joins near Banatska Palanka. The Nera rises in the Semenic mountains, the easternmost part of the Banat region, south of the city of Reșița, in the Caraș-Severin County of Romania. The river starts at the confluence of headwaters of the Nergana and Nerganița then flows straight to the south from the Piatra Grozbe peak, under which it springs. Reaching the village of Borlovenii Vechi, the Nera turns southwest, flowing between the Semenic and Banat
Koshi River north, the Gandaki in the west and the Mahananda in the east. The river is joined by major tributaries in the Mahabharat Range approximately north of the Indo-Nepal border. Below the Siwaliks, the river has built up a megafan some in extent, breaking into more than twelve distinct channels, all with shifting courses due to flooding. Kamalā, Bāgmati (Kareh) and Budhi Gandak are major tributaries of Koshi in India, besides minor tributaries such as Bhutahi Balān. Its unstable nature has been attributed to the heavy silt it carries during the monsoon season and flooding in India has extreme effects. Fishing
