Abstract
In this study, the application of the resilience concept of the flood event depending on progress of the time is analyzed as the hazard occurrence, the disaster risk, the damage risk, and the evolution of the damages. Flood disaster is defined as the occurrence of an inundation in an exposed area. The human exposure (loss of life, injury, …), structural (buildings, roads, …) and functional (economic, political, … functions of an area) economic exposure cause high risk of damage if the area in which the hazard occurs is at low resilience. Furthermore the damage will increase without adequate response against disaster. The flood disaster risk is decreased by flood control measures, reducing structural and functional exposure. Non-structural measures, such as appropriate prior-evacuation, decrease the human exposure to flood disaster. This study reviews the events of 2000 and 2011 floods in the Shonai River basin in Japan to help assess resilience to flood disaster. These two events had the same type of hazards in intensity and location, allowing the study in terms of adaptation to flood disaster in the river basin to focus on the structural and nonstructural effort to increase resilience of the disaster depending on progress of the time.
Highlights
Flood disaster is one of the major natural disasters around the world in terms of frequency, victims and economic losses [1]
From the above recognition of the topics, firstly in this paper we review the characteristics of floods in Japan ; we will present the definitions of several concepts used in this study to assess the adaptation to flood risk by increasing structural and non-structural measure to fight flood risk
In order to overcome such vulnerability or to increase resilience against flood disaster and the subsequent damages, we have to prepare firstly structural measures to reduce the structural and functional exposure, the nonstructural measures to reduce the human exposure against damages by inundation, and the disaster management system has to support rapid recover and restoration to reduce the expansion of damages
Summary
Flood disaster is one of the major natural disasters around the world in terms of frequency, victims and economic losses [1]. (2015) Adaptation of Resilience against Disaster—Case Study of 2000 Tokai Flood and 2011 Flood in Shonai River, Japan. From the above recognition of the topics, firstly in this paper we review the characteristics of floods in Japan ; we will present the definitions of several concepts used in this study to assess the adaptation to flood risk by increasing structural and non-structural measure to fight flood risk. Two floods occurred in the Shonai River basin in 2000 and 2011, and we analyze how the adaptation of resilience against flood disaster was achieved
