Application and Assessment of GIS Technology in Flash Flood Risk Management

Abstract

This paper aims to explore the application of Geographic Information Systems (GIS) technology in the risk management of flash flood disasters and its role in safety assessment. Initially, the article briefly introduces the basic principles and functionalities of GIS technology, as well as how it can be effectively used in the monitoring, analysis, and prediction of flash flood disasters. Subsequently, the paper delves into the key applications of GIS in the risk assessment of flash floods, including the identification of disaster-prone areas, classification of risk levels, and planning of response strategies. The article also emphasizes the advantages of GIS technology in integrating multi-source data, achieving dynamic monitoring, and enhancing the efficiency of emergency response. Finally, through an analysis of existing research, the paper points out the potential and future directions of GIS in the field of safety evaluation of flash flood disasters. This study aims to provide more effective technical support and decision-making references for the risk management of flash flood disasters.
