Permeability Apparatus Falling Constant Head is a popular testing method which is utilized for the purpose of determining the permeability of the fine-grained soil with slightly lower permeability such as clay and silts. The instrument that is used for measuring the permeability is called permeameter or permeability apparatus. The results obtained are used for the purpose of pumping the groundwater for designing the dams and for excavations.

The soil falling constant head permeability test apparatus can be done on remolded or samples that are undistributed by using the falling or constant head method. The falling head permeability test mainly includes water flow through a sorter soil sample that is connected to a standpipe. The standpipe in return provides for the water head and allows for the measuring of the volume the water that passes through the samples. The test can be conducted in a simple falling head permeability cell or it can also be conducted in an pedometer cell.

The apparatus is mainly utilized for the laboratory determination of permeability of the soil with the help of a constant or a variable head. This test is suggested for the soils having the co-efficient permeability that ranges between 0-10-3 to 10-7 cm/sec. The maximum size of the particle of the soil which the mould can test is 10mm
