Construction and technical application in the digital twin irrigation development in the three large irrigation schemes at Binzhou City of Shandong Province

Abstract

The three large irrigation schemes, namely Bojili, Xiaokaihe and Handun irrigation scheme, in Binzhou City of Shandong Province include in the pilot list of digital twin irrigation schemes by the Ministry of Water Resoucres. This paper systemically introduced the overall design structure of digital twin irrigation scheme for the three large irrigation schemes, as well as the construction components and technical approaches for the digital twin irrigation development in the three irrigation schemes, including, data base, vertical monitoring system, canal automation, models, support system and management platform, etc. The construction of the digital twin irrigation schemes in the three large irrigation schemes in Binzhou City is based on the existing information system. The total investment has reach more than 42.8 million RMB Yuan, and the major part of the pilot project has completed and put into use successfully and received good application results. The application of water schedule model could reduce planning time by 60% and saving water by 6%, and canal automation could save labor by 40%. With the further development, updating and application of the digital twin irrigation technology in the three large irrigation schemes, irrigation water management can be further improved by increasing digital, intelligent and precise management, which will contribute to high quality and sustainable development of irrigation schemes.
