Falling Head Test

The Falling Head Test is a method used to determine the permeability of soil or rock. In this test, a column of water is maintained at a specific height above a soil sample. As water drains through the soil, the height of the water decreases over time. By measuring how quickly the water level falls, engineers can calculate how easily water can flow through the soil. This information is important for construction projects, groundwater studies, and assessing drainage capabilities, helping to ensure the stability and safety of structures built on or in the ground.
