Constant Head Test

The Constant Head Test is a method used to measure the permeability of soil, which indicates how easily water can flow through it. In this test, water is kept at a constant level, and the flow rate of water through a soil sample is recorded. This helps engineers and scientists understand the soil's drainage capabilities, important for construction, agriculture, and environmental assessments. A higher flow rate typically indicates more permeable soil, while a lower flow rate suggests that the soil retains water more effectively.
