description: The project is dedicated to determining the optimal configuration of the pressure front that meets the requirements of the compiled mathematical model. The author of the study proposed a mathematical model of numerical nonlinear optimization of the pressure front of a low-pressure hydraulic unit using design automation tools. Research objectives: To analyze the existing methods of calculation, modeling of spillway structures, as well as automation tools for the design of GTS based on the analysis of literary sources, scientific papers, Internet resources and regulatory and technical documentation; To create a model of nonlinear numerical optimization to calculate the optimal variant of the pressure front of the hydraulic unit; To develop a computer program for automating the calculation and modeling of GTS in the environment of the nanoCAD platform; To develop a method for the multivariate design of a low-pressure hydraulic unit on a non-rock basis using the developed computer program and the nanoCAD platform. According to the results of the study, it was concluded that the traditional methods of calculating hydraulic structures are reliable, time-tested and almost completely satisfy the design needs at the stages of detailed elaboration of project documentation. However, at the stage of conceptual and pre-design study, existing methods can be labor- and time-consuming due to the uniqueness of the conditions for the construction of hydraulic structures and the change in parameters from project to project (as well as from alignment to alignment on the same river). The author proposes a method of multivariate design, which significantly reduces the time for calculations and development of a 3D model of a hydroelectric power plant with obtaining the cost of materials for the construction of an underground and spillway dam. During the research, a mathematical model was compiled and a HydroCAD computer program was developed, the method of multivariate design was tested on given initial data, a conceptual 3D model of a low-pressure hydraulic unit was obtained for 19 variants of the spillway dam configurations, and optimization graphs for the projected hydraulic unit were constructed.
