Who postulated the concept of hydraulic gradient?

The concept of hydraulic gradient is fundamental in the study of fluid mechanics and hydrology, and it was postulated by Henry Darcy. Darcy's work in the 19th century laid the foundation for understanding the movement of water through porous media. He introduced the idea that water flow through soil or any porous medium is influenced by the hydraulic gradient, which is the change in hydraulic head per unit distance. This principle is a crucial aspect in both groundwater studies and the design of water systems.

Darcy's Law, which describes the flow rate of water through soil in relation to this gradient, has significant applications in various fields such as civil engineering, environmental science, and hydrogeology. Understanding the hydraulic gradient is essential for predicting water movement and for effective water resource management.
