Inland waterways are navigable bodies of water, such as rivers, lakes, and canals, that are used for transportation and trade. These waterways provide an efficient means of moving goods and people, often connecting rural areas to urban centers. They play a crucial role in reducing road congestion and lowering transportation costs. Inland waterways can also support recreational activities, such as boating and fishing, contributing to local economies. Many countries invest in maintaining and improving their inland waterway systems to enhance trade and tourism. Examples include the Mississippi River in the United States and the Rhine River in Europe.
