On an on-farm irrigation network, often the geometric dimensions and cross-sectional profile of the water conduit are dictated by the physical need for its throughput in a given area. The question about the rational transverse profile of the conduit directly related to its stress-strain state during operation. Production and operational experience shows that the installation of water conduits is carried out without a proper analysis of the total stresses in the soil and in the structures themselves. The object of study is a water conduit with a rectangular cross section under the influence of various loads on it: static, dynamic, and their combinations.
