Abstract：Smart water conservancy signifies high-quality development in the water conservancy sector.To address challenges in smart water conservancy construction,such as incomplete theoretical frameworks,low accuracy in watershed mapping,and inadequate model precision,we established a smart water conservancy theoretical system composed of smart watershed,digital twin watershed,and intelligent water network theories.We investigated digital twin watershed perception models,including digital twin perception node optimization,precipitation remote sensing,evapotranspiration remote sensing,soil water remote sensing,lake water remote sensing,groundwater remote sensing,and water quality remote sensing models.Additionally,we constructed digital twin watershed virtual models encompassing hydrological,hydrodynamic,water quality,dynamic regulation,virtual simulation,collaborative decision-making,and parallelized combination models.These research outcomes offer theoretical foundations and technical support for smart water conservancy construction in China.
