FIELD: measurement equipment.
SUBSTANCE: invention relates to the field of study of soil parameters. The method of determination of filtration coefficient of running soil is offered according to which through the soil sample the water flow is passed, on the surface of the soil sample of a small weight is places, the moment of start of sinking of the small weight, the parameters of the sample and water flow are measured, the soil filtration coefficient is calculated using the measured indicators. The innovation is in that the value of concentration of polyacrylamide in the water flow passed through the soil sample is registered and at decrease in value of concentration by more than 8% from the initial value the polyacrylamide solution is added into the water flow directed towards the soil sample, thus recovering the value of polyacrylamide concentration in the water flow passed through a soil sample, to initial value.
EFFECT: expansion of functionality is achieved.
