Mountain torrent disaster warning system is a significant non-engineering flood prevention measure for achieving the goals of flood prevention and disaster reduction in the related small rivers. After analyzing the design principle and objective of the system, we proposed a mountain torrent disaster warning system based on WEB GIS technology and the distributed hydrological model (DHM) of the r...

Flood risk analysis is subject to uncertainties, often severe, which have the potential to undermine engineering decisions. This is particularly true in strategic planning, which requires appraisal over long periods of time. Traditional economic appraisal techniques largely ignore this uncertainty, preferring to use a precise measure of performance, which affords the possibility of unambiguousl...

Flood is one of the most important natural disasters affect China greatly, especially for southeast cities. To help mitigate the loss brought by it, technologies such as simulation, visualization, decision support system, etc. could be utilized in the process of emergency management for city flood. Thus the Flood Simulation and Decision Support System (FSDSS) comes into being. It is an integrat...

Of all natural disasters, flooding causes the greatest amount of economic and social damage. The United States' Federal Emergency Management Agency (FEMA) uses a number of hazard mitigation grant programmes for flood victims, including mitigation offers to relocate permanently repetitive flood loss victims. This study examines factors that help to explain the degree of difficulty repetitive flo...

Climate change and accelerating socioeconomic developments increasingly challenge flood-risk management in the Vietnamese Mekong River Delta-a typical large, economically dynamic and highly vulnerable delta. This study identifies and addresses the emerging challenges for flood-risk management. Furthermore, we identify and analyse response solutions, focusing on meaningful configurations of the ...

This paper presents the findings of an analysis of flood disaster trends in Asian countries during the last 30 years. The analysis was carried out to understand the changing characteristics of flood disasters in Asian countries in the past three decades with the rapid changes in socio-economic conditions. The second half of the paper presents the results of a modeling study of flood risk manage...

It is now commonly accepted that the management of flood risks has to be fulfilled within an integrated framework. About two decades ago flood risk was managed from a limited perspective predominantly by means of structural measures aimed at flood control. In contrast integrated flood risk management incorporates the complete management cycle consisting of the phases prevention, protection and ...

Attempts at flood management during the 20th century resulted in more flood disasters. To gain a better understanding of what went wrong, it is necessary to examine historical evidence, seek ancient wisdom and compare practices of flood management in different countries. This study examines flood management concepts and practices in China and Japan during different periods of time in history an...

Economical integration of permanent and emergency flood control options is a long-standing problem in water resources planning and management. A two-stage linear programming formulation of this problem is proposed and demonstrated which provides an explicit economic basis for developing integrated floodplain management plans. The approach minimizes the expected value of flood damages and costs,...
