Determining the Intrinsic Permeability of Frazil of Frazil Ice. Part 2. Field Investigations
The intrinsic permeability of a frazil deposit can be used to describe its flow capacity and structure. Because of the nature of frazil ice, an in-situ test is desirable when determining this parameter in natural frazil deposits. This report describes the application of the borehole dilution test to...

The intrinsic permeability of a frazil deposit can be used to describe its flow capacity and structure. Because of the nature of frazil ice, an in-situ test is desirable when determining this parameter in natural frazil deposits. This report describes the application of the borehole dilution test to determine seepage velocity, which is then used to calculate intrinsic permeability and estimate porosity. Seepage velocities ranged from 0.29 x 10-3 to 5.98 x 10-3 cm/s (2.56 x l0-3 cm/s average), with an average intrinsic permeability of 2.75 x 10-4 cm2. Porosities for d10 grain sizes of 0.5 and 3.5 were 82.9 and 47.5 %, respectively. Seepage velocity and porosity data are also compared to laboratory data from borehole dilution tests, data measured previously at the same location with an in-situ groundwater flow meter, and to permeameter test results on remolded samples.
