Does the River Seine Have a Waterfall?

No. The Seine is a lowland river flowing 777 km (483 mi) from Source-Seine (Côte-d'Or) to the English Channel at Le Havre. Its gradient is gentle (avg. 0.1%), with no natural waterfalls.

Artificial "Falls"

• Weirs & locks: 37 navigation structures (e.g., Suresnes, Bougival) create small drops (1–3 m) for water level control.
• Paris: 3 weirs within city (Austerlitz, Marie, Garigliano) – modest cascades, not waterfalls.

Why No Natural Falls?

Geology: Paris Basin sedimentary rocks (limestone, chalk) erode evenly. No resistant caprock or glacial hanging valleys. Contrast with Rhône (Alpine) or Nile (cataracts).
