"강" is the Korean word for "river." It refers to a natural watercourse that flows towards an ocean, sea, or lake. Rivers are essential for ecosystems, providing habitats for various species and serving as a source of freshwater for human consumption and agriculture. In South Korea, notable rivers include the 한강 (Han River) and 낙동강 (Nakdong River). These rivers play a significant role in the country's geography and culture, supporting transportation, recreation, and tourism. Rivers also contribute to the economy by facilitating trade and providing resources for industries.
