As critical national space infrastructure and a strategic public resource, low Earth orbit(LEO) internet satellites, with their core advantages of wide coverage, low latency, high reliability, and strong resilience, together with their integrated communication-navigation-remote sensing service capability, provide novel technical support for the high-quality development of the water conservancy and the construction of smart water conservancy. At present, the water conservancy sector still faces challenges in core scenarios such as routine monitoring data acquisition and transmission and emergency response to sudden-onset floods and droughts, including blind spots in monitoring coverage, unstable data transmission, poor data sharing, and weak emergency communication, making it difficult to meet the development requirements of full-domain perception, rapid response, and intelligent decision-making. Based on the above industry needs, this paper systematically examined the correspondence between current pain points in the water conservancy and the capability supply of the new-generation space infrastructure. Drawing on the capabilities of LEO internet satellites in integrated communication, remote sensing, and navigation, as well as signals-of-opportunity remote sensing applications, it analyzed their compatibility with water conservancy business requirements from four dimensions: widearea coverage and low-latency communication, large-capacity data transmission, rapid emergency response, and communication-remote sensing integration. On this basis, the paper explored typical integrated application scenarios such as routine monitoring assurance, emergency disaster response, and cross-regional coordination, and proposed key technology innovation paths for water conservancy business integration, aiming to promote the deep integration of LEO internet satellites with water conservancy, comprehensively enhance water security assurance capabilities and the level of digital water governance, and provide a reference for the construction of smart water conservancy and the development of new quality productive forces in water conservancy.
