Abstract
1. The papers reviewed are mainly interesting in respect of diversity, of both the problems tackled and methods of investigation, hydraulic, hydromechanic, physical, and mathematical modeling, the use of mathematical statistics procedures, and computers. The methods formulated in the USSR have been recognized abroad, although the corresponding literature is not always sufficiently use. (See for example “The Development of Investigations into Seepage Theory in the USSR,” published by Nauka, 1969). 2. Some of the papers point to new possibilities in the calculation of nonlinear seepage, transient processes, two-phase seepage, the interaction of different liquids, in addition to liquids with a soil “skeleton,” and finally seepage as an economic index in the search for optimum volumes and profiles of earth structures. 3. Some of the data from systematic experiments contained in the papers may prove useful for the definition of standards used in the calculation of seepage under conditions where the Darcy law is not applicable, both in the field of low seepage velocities (for example in clays) and high seepage velocities (for example in the zones of action of drainage).
