Complete step by step solution:
Volga River, Russian Volga is the continent’s longest river. It is also the principal waterway of western Russia. It marks the historic cradle of the Russian state. Its basin is expanded across two-fifths of the European part of Russia. It consists of almost half of the entire population of the Russian Republic. Volga river carries immense economic, cultural, and historic importance to its people. With the sheer size of the river and its basin, it ranks among the world’s greatest rivers. Also, a lot of people consider it as the national river of Russia. The western part of the country is where the river has set its course. As established, it is Europe's longest river, by a length of 3,530 kilometers. Rising in the Valdai Hills of Russia, 225m above sea level north-west of Moscow, it constitutes the core of the largest river system in Europe. Kama, Oka, Vetluga, and the Sura are the main tributaries of Volga. The Volga and its tributaries form the Volga river system or Volga Delta drains an area of about $1.35$ million square kilometers in Russia. The Volga Delta has sprawled to about 160 kilometers. The Volga river system has 555 channels and small streams making it the largest estuary in Europe. Pelicans, flamingos, and lotuses are found only in this Delta.
