Pierre de Saint-Venant
Pierre de Saint-Venant was a 19th-century French engineer and mathematician known for his work in fluid mechanics and elasticity. He developed fundamental equations, called the Saint-Venant equations, which describe how water flows in open channels and rivers, accounting for forces like gravity and friction. These equations help engineers design efficient waterways and predict water movement. His contributions provide a practical understanding of fluid behavior in natural and artificial channels, making his work essential for hydraulics and civil engineering projects.
