The constant head permeability test is a laboratory method used to determine the permeability of granular soils, like sands and gravels, by measuring the flow of water through a soil sample under a constant pressure difference (head).
Here's a more detailed explanation:
Purpose:
This test is used to determine the coefficient of permeability (k), which indicates how easily water can flow through a soil.
Method:
A cylindrical soil sample is placed within a permeability cell (also called a permeameter).
Water is passed through the sample from a constant level tank, maintaining a constant hydraulic head (pressure difference) across the sample.
The flow rate of water through the sample is measured.
Applicability:
Best suited for coarse-grained soils (like sands and gravels) with relatively high permeability.
