CONCEPT OF A DIGITAL TWIN FOR WATER MANAGEMENT IN IRRIGATION SYSTEM

Abstract

The analysis of modern challenges of water resources use in irrigated agriculture under conditions of growing population, developing production, climate change is carried out, and the state of water use management in the domestic reclamation water management complex is characterized. The prospect of application of digital twin technologies as an effective approach to optimization of water use management in inter-farm irrigation system is substantiated. The concept of digital twin control model as a basis for use in the practice of reclamation water management complex operation service is presented. The purpose of creating a digital twin model for water management in inter-farm irrigation systems is to ensure efficient and sustainable systemic water use based on optimizing water distribution and water consumption, increasing agricultural land productivity, and reducing the negative impact on the agricultural landscape. The list of model tasks includes: modeling of water use processes; optimization; monitoring and analysis of the control system state in real time; analysis and assessment of the impact of external factors; forecasting; decision-making support and generation of alternative scenarios for water use management; efficiency assessment; algorithm development; sensitivity analysis and identification of critical factors; integration with other systems. The structure of the model of digital twin of the process of water use management of inter-farm irrigation systems is proposed and the structural-functional scheme "Digital twin of the process of management of technical operation of irrigation system" is developed, the central link of which is the model of technical operation optimization as a special case of the model of water use optimization.
