Canal systems are man-made waterways designed to facilitate the movement of water and goods. They connect rivers, lakes, and oceans, allowing boats and ships to travel more efficiently. These systems often include locks, which help manage changes in water levels, making it easier for vessels to navigate different elevations. Historically, canal systems played a crucial role in trade and transportation. Notable examples include the Panama Canal, which connects the Atlantic and Pacific Oceans, and the Erie Canal in the United States, which links the Hudson River to Lake Erie. These canals have significantly impacted economic development and regional connectivity.
