Research on the application of the multi-objective coordination Four-Preparation scheduling system in typical plain river networks: A case study of Kunshan

Kunshan, a typical river network city located in the Taihu Plain, has a dense network of rivers, with upstream receiving discharge from rivers and downstream supported by multiple tributaries entering the Yangtze River. Additionally, the citys internal embanked areas are numerous. Furthermore, the existing information system was constructed prematurely and lacks professional forecasting and simulation technologies, making it difficult to fully grasp the current water security situation and rapidly display the effects of scheduling plans. This study analyzes the Four-Preparation integration and proposes improvements. Based on Kunshans current situation, the goal is to construct an Integrated Four-Preparation System, establishing a scientific coupling system for forecasting, early warning, rehearsal, and contingency planning. This will strengthen intelligent and smart development applications to achieve scientific disaster reduction.
