WebDec 16, 2024 · Darcy's Experiments and Darcy's Law In 1855, Henri Darcy, a French hydraulic engineer (Figure 24), oversaw a series of experiments aimed to understand the rates of water flow through sand layers, and their relationship to pressure loss along the flow paths. WebDarcy’s law states that flux of water through saturated po rous media is directly proportional to the hydraulic gradient. The negative sign in the equation signifies the fact the water flows ...
