Canal networks are systems of interconnected waterways designed for navigation, irrigation, or drainage. They can be man-made or natural and often include canals, rivers, and lakes. These networks facilitate the movement of goods and people, enhancing trade and transportation in various regions. In addition to their economic benefits, canal networks also support agriculture by providing water for irrigation. They can help manage water levels and prevent flooding in surrounding areas. Famous examples of canal networks include the Panama Canal and the Suez Canal, which are crucial for international shipping and trade.
