What problems did canals face?

Canals faced several challenges, including sedimentation, which led to the need for regular maintenance to prevent blockages. They were also vulnerable to weather conditions, such as flooding and drought, which could disrupt navigation and water levels. Additionally, competition from railroads and road transport emerged in the 19th century, leading to a decline in their usage and economic viability. Finally, environmental concerns arose, as canals could disrupt local ecosystems and water quality.
