Abstract：Monitoring and perception should be the premise and foundation of digital twin water resources. Application of monitoring or perception only can no longer meet the requirement for whole-process intelligent perception of all elements of water resources objects and water governance and management. Developing "sky-space-earth-water-project" integrated monitoring and perception system is urgent for monitoring and early warning of natural disasters,and an inevitable trend for developing new water conservancy productivity and a basis for improving quality and efficiency of digital twin water resources. Introductions are made on the overall framework,basic principles,and construction goals,with a focus on four aspects of technologies and equipment,communication security,data collection,institutional mechanism and standards. It aims to enhance monitoring and perception capabilities in six areas,including water and drought disaster prevention,water resource management and allocation,project construction and operation,river and lake chief system and governance,soil and water conservation,irrigation and drainage and rural water supply and hydropower development. Discussions are also made on the implementation path of "sky-space-earth-water-project"integrated monitoring and perception system,as well as measures of strengthening leadership,finance,scientific and technological innovation,and support of talents. The case of using monitoring and perception system to deal with breach of the Tuanzhou embankment in Hunan Province was evaluated. The research findings can provide reference for the comprehensive establishment of an integrated monitoring and perception system that covers "sky-space-earth-water-project"and support the development of a digital twin for water resources with full-element,high-fidelity "four-pre" (prediction,pre-warning,pre-emption,and preparedness) capabilities.
