Core Viewpoint - The article discusses the implementation of a digital twin system and decision support system in China's water management, focusing on the "Four Pre" functions which are essential for flood and drought disaster prevention [1][4]. Group 1: The "Four Pre" Functions - The "Four Pre" refers to forecasting, early warning, rehearsal, and contingency planning, which are the core functions of smart water management [4]. - Forecasting serves as the foundation, utilizing mathematical models to predict various water safety factors such as precipitation, water levels, and soil moisture, thereby providing valuable time for flood prevention efforts [3]. - Early warning acts as a frontline measure, delivering timely information to frontline water management teams to guide emergency responses like engineering inspections and personnel evacuations [6]. Group 2: Simulation and Planning - Rehearsal involves simulating typical historical events and future scenarios within a digital twin watershed to formulate risk mitigation measures [8]. - Contingency planning is based on rehearsals, taking into account actual engineering and social conditions to develop actionable engineering and non-engineering measures, ensuring the feasibility of the plans [10]. - The four components are interconnected and progressively build a safety defense line for smart water management [10].
