Abstract:

Forecasting and early warning of water quality are essential for advancing the modernization of water pollution prevention. In this study, we developed a technical framework for a phosphorus risk assessment platform and implemented a water environment platform for phosphorus risk forecasting and early warning. The platform automatically collects and integrates multi-source heterogeneous foundational data, including meteorological, hydrological, water quality monitoring, and pollution source discharge data, and generates boundary and process conditions for an air-land-water coupled model. The platform forecasts rainfall, hydrology, and total phosphorus concentrations, assesses phosphorus-related risks, and issues early warnings. The platform was applied to the Xiangxi River basin in 2016 and 2020, and has provided technical support for enhancing intelligent basin management and mitigating phosphorus risks in the Xiangxi River basin.

Key words: water environment, phosphorus risk control, forecasting and early warning platform, business application, Xiangxi River basin
