This document describes the process and results of a constant head permeability test conducted on a sand sample. Key details include: - The test was used to determine the coefficient of permeability (k) of the sand, .The falling head method of determining permeability is used for soil with low discharge, whereas the constant head permeability test is used for coarse-grained soils with a reasonable discharge in a given time. For very fine-grained soil, capillarity permeability test is recommended. Usually, permeability of soils is determined by two methods: 1.
