What are the importances of the following four rivers: Volga, Dnieper, Dniester, Danube?
Volga - The Volga River is the longest river in Europe and Russia's most important waterway. Originating northwest of Moscow, the Volga and its many tributaries carry more freight and passenger traffic than any other river in Russia. It provides hydroelectric power and water to many parts of Russia.
Dnieper - The Dnieper River also originates in Russia. It flows through Belarus and Ukraine before empting into the Black Sea. Dams and reservoirs southeast of Kiev provide hydroelectric power. They also irrigate farmlands and help relieve water shortages in parts of Ukraine.
Dniester - Originating in the Carpathian Mountains and emptying into the Black Sea, the Dniester River is the second-longest river in Ukraine. The Dniester carries freight and passenger ships, and it serves as an important route to the Black Sea.
Danube - From its origins in southwestern Germany, the Danube flows toward the east through several countries before emptying into the Black Sea. The Danube provides transportation, hydroelectric power, fishing, and water for irrigation. Historically, the river transported traders as well as invading armies. Today, many cities are located along its banks, including three capital cities: Vienna, Austria; Budapest, Hungary; and Belgrade, Serbia. The Main River became connected to the Danube via the Main-Danube Canal, which linked the North Sea with the Black Sea.
