Abstract: Purpose: to analyze and summarize the results of research by domestic and foreign scientists devoted to the theory of filtration from drainage canals. Discussion. The analysis was based on the results of research conducted by domestic scientists in the USSR and the Russian Federation, foreign research, and the author’s own data on the methods of calculating filtration from irrigation and drainage system canals. The results of research by domestic and foreign scientists aimed at developing the theory of filtration in the field of irrigation canals and drainage systems are summarized, and the main shortcomings, information on which has been obtained by various authors over more than 80 years of the development of the filtration school in relation to drainage canals are identified. The fundamental methods currently used for solving filtration problems through impervious screens (including those that are susceptible to damage), including experimental, theoretical, experimental-theoretical, and numerical methods are considered. The calculation dependencies used for filtration calculations of irrigation canals, based on classical methods of filtration theory, are presented. Conclusions. New (not previously considered) problems aimed at studying the permeability of reclamation canal coatings (primarily main and irrigation) made of geosynthetic polymer and bentonite materials are revealed. Methods used for solving problems of water permeability of geosynthetic impervious screens of irrigation canals are considered. In the domestic literature there are only individual publications that touch upon the issues of using modern construction geosynthetic materials on reclamation canals. There are practically no studies devoted to the issues of water permeability of geosynthetic bentonite materials, in particular, taking into account self-healing of damage due to the complexity of solving such problems.
