Abstract Analysis of a mathematical model of water movement in a multi-tiered curvilinear capillary shows that in the multilevel capillary systems with curvilinear lateral capillary the water distribution in the branches is not the same. The greatest movement occurs in the the lowest level branches. The absolute value of the water movement changes depending on the number of levels in the system, the distance between them and parameters of a mathematical function which describes the curvature of the branches capillary. In multi-tiered curvilinear capillaries a decrease in the distance between the levels leads to an increase in water movement in each of the curved lateral branches. In a vertical capillary multilevel system of curved capillaries, the presence of side branches leads to increased recovery of water compared with a single vertical capillary of the same radius. The height of water rise in a vertical capillary system, ceteris paribus remains the same regardless of the side branches. In curved capillary systems, the movement of water in the capillaries of the higher levels relative to the first capillary having leveraged is greater as compared to the straight capillaries of the same levels. The absolute value of the water movement in the rectilinear lateral branches depends on the angle of inclination to the horizontal, the number of levels in the system and the distance between them, curved side branches, the absolute amount of promotion of water depends on the number of levels in the system, the distance between them, and curvature of the branch. In the considered layered capillary systems manifested is the following, common to all considered capillary systems feature of water distribution. A figure, formed by connecting an imaginary line connecting the water meniscus in the capillary branches, and in a vertical capillary, resembles a specific form of wood or leaf. This confirms the assumption that plants have their specific form owing to the presence of capillary systems.
