Based on experimental investigations carried out under 
laboratory conditions, the features of filtration and infiltration 
of a liquid have been studied in a linear model of a bed. The model 
consisted of two zones of different permeabilities and was manufactured 
in the form of a cylindrical tube of length 1.1 m and inside diameter 
0.032 m. It has been shown that, in filtration of water from a lower 
permeability to a higher one, the productivity coefficient increases, 
on the average, by 15% as compared to infiltration. The mechanism 
of the phenomena observed has been proposed.
