Constant Head Permeability Test

The Constant Head Permeability Test is a method used to measure how easily water flows through soil. In this test, a steady water level is maintained in a container above the soil sample, allowing water to seep through it. By measuring the amount of water that passes through over a specific time period, and knowing the dimensions of the soil sample, engineers can calculate the soil's permeability. This information is essential for understanding soil behavior in construction, drainage, and environmental studies, as it helps predict how water will move through the ground.
