Practices and thinking of water quality safety construction of digital twin Danjiangkou
Jiang Rong
Abstract：As the water source and a basic prerequisite for safe and stable operation of the South-to-North Water Diversion Project,the Danjiangkou Reservoir must ensure its water quality.Along with development of informatization and intelligence,digital twin technology has a broad applicable prospect for ensuring water quality and reservoir management.Discussions are made on the importance of ensuring water quality safety of the the Danjiangkou Reservoir and weakness of traditional management approaches.A core technology system involved in digital twin Danjiangkou water quality safety block is introduced based on the needs of water quality management in the reservoir,including high-precision collaborative perception and fusion governance technology for water quality dynamics,a model base for water quality safety based on"data+mechanism"model coupling and"Forecast,early warning,rehearsal and plan"technology.Practical application of automatic monitoring station for total phosphorus increase and sudden water pollution event prediction during the 2024 flood season in Qingshan demonstrates the effectiveness of digital twin Danjiangkou construction.At the same time,short board and weakness in terms of forecasting accuracy,prediction period,data integration,capability of model generalization and"Forecast,early warning,rehearsal and plan"business application are discussed.Focusing on key directions of technological upgrading,optimization and integrated expansion,ideas for following works of building water quality safety block for digital twin Danjiangkou and future prospect are proposed.
