Design of Villages and Towns Flood Disaster Simulation and Emergency Decision Support System

Abstract

China is a country prone to natural disasters, especially the flood disaster. In order to improve the villages and towns flood emergency management, through a series of methods such as information management and simulation, the establishment of emergency decision support using information technology to reduce losses caused by floods, the visualization technology is used in the virtual reconstruction model of floods, intuitive way to simulate the dynamic spread of the process of the flood disaster, in a safe and economical method to obtain the number of indicators of disaster-related decision. It provides a new method and ideas, and then it gives a reliable basis for the flood prevention and emergency management. The visualization analysis and decision is achieved for the villages and towns flood control, and it provides great support for the villages and towns flood mitigation and prevention. The result shows that the system is useful and meaningful in the town flood mitigation.

Intelligent Flood Disaster Forecasting Based on Improved Neural Network Algorithm

“…The forecasting and assessment of flood disaster is a non-engineering measure to prevent flood in recent years Parker, 2004;Sene, 2008;Boosik et al, 2010;Todini, 1999;Hijji et al, 2017;Song et al, 2012). Due to the suddenness, complexity and other characteristics of flood disasters, there are many defects in traditional disaster assessment and forecasting, such as poor timeliness, low prediction accuracy, and large gaps between forecasting and assessment results and the actual results (Yan, Fan and Jing, 2017;Wang and Cheng, 2008;Morita and Fukuda, 2002;Qing and Qiang, 2007).…”
