Abstract

The aim of the research was to develop an algorithm for modeling the regulation of water resources in the fields of reclamation systems for dual regulation of the water regime of soils (drainage-moistening, drainage-irrigation) in the «group of water consumers» contour (crop rotation plot) for the subsequent development of information and software tools that provide the possibility of operational regulation of water resources on dual regulation systems. The information and methodological basis of work related to modeling the modes of distribution of water resources in crop rotation plots was made up of methods for collecting and processing information, systematization methods, regulatory and technical documents, provisions for the development of information technologies, as well as existing means of information technology support for tasks in land reclamation. The task of modeling was to determine the modes of water supply from a water source (regulating tank, water intake-water source) by a pumping station by controlling the on and off of pumping units of different capacities available on it under conditions of rapidly changing water intake modes in the circuits regulation «Water consumers». The algorithm for modeling water regimes in the control loop «Group of water consumers» (crop rotation area) in the reclamation SDR includes three stages: preparation – input of initial data on water consumption plans in the control loops «Water consumer»; modeling – cost calculation; simulation results – total volumes of water to be supplied to the site, total volumes of water from the control tank or water-receiver-water source, and others. The developed algorithm makes it possible to quickly regulate the modes of water supply from a control tank or a water-receiver-water source by pumping stations by controlling pumping and power units under conditions of rapidly changing water intake modes in the «Water consumer» control loops.
