Purpose: to develop software for the process of arranging sprinklers on the water-conducting belt of a sprinkler to improve the irrigation quality. Materials and methods. As a theoretical basis for creating software, the traditional methods of algorithmization and programming based on the processes of algorithm design for solving the problem of calculating the optimal spacing and flow-pressure characteristics of deflector nozzles on the water-conducting belt of sprinklers, respectively, formalized in the form of a scheme, and writing the source code in the object-oriented programming language Python were used. Results. To replenish the domestic scientific and technical base for digitalization of engineering and reclamation work with information tools, software for the process of arranging sprinklers on water-conducting belt of a sprinkler for uniform distribution of artificial rain along the irrigated area has been developed. The algorithm graphical model is represented by three blocks. The “Source data input” block provides a choice of the type of sprinkler, the operating flow rate of irrigation water, as well as the material of the water conducting belt. In the “Intermediate and target values calculation” block, the irrigation water loss, head loss, distance between the end and first nozzles, as well as the total number of sprinklers are calculated. In the “Cyclic computation and output of results” block, head losses along the length and local pressure losses are determined for each section, the sum of which makes up the total head losses. Using the designed software, computations were performed using the example of a cantilever sprinkler with 4 sections of steel pipeline, a total flow rate of 6 l/s and a pressure at the end of the console of 10 m. It was determined that to ensure the uniform distribution of artificial irrigation along the irrigated area, it is necessary to install 9 sprinklers with variable spacing along the length console, and to provide a head at the beginning of the sprinkler machine of 23.8 m, taking into account the total head loss of 13.8 m. Conclusions: the software allows simulating the optimal arrangement of deflector nozzles of the same size on a water-conducting belt at the design stage of double-cantilever and multi-tower lateral sprinklers.
