Water emergencies occur frequently in China, which serious influence the security of city water supply. An emergency dispatch model for urban water supply was conducted base on the water supply network graphs, the model can give emergency dispatch scheme of urban water supply using some operation rules as far as possible to ensure the safety of water supply or the least affected premise. Selecting Anyang as the experiment, the emergency dispatch system was developed. Provide technical support and decision-making platform to improve the emergency response capacity of city water supply emergencies.
In view of the present situation of frequent flood and drought disaster in China, and lacking of technology for emergency hydrologic monitoring system and emergency response analysis. Face to emergency hydrologic forecast, this paper study on hydrologic information extraction and flood inundation risk emergency, and set up emergency hydrologic analysis system with the function of emergency hydrologic information extraction, flood simulation, flood analysis and hazard evaluation and so on. The system provided technical support and analysis platform for emergency hydrologic monitoring, forecasting and decision making.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
