Assessing the Risks of Typhoon-Induced Multi-Hazards in South Korea

TL;DR

This paper reviews data, models, and methods for assessing individual and combined typhoon-induced hazards in South Korea, emphasizing adaptation of North Atlantic approaches to local contexts.

Contribution

It evaluates existing hazard assessment approaches and explores their adaptation and extension for South Korea's unique coastal risk management needs.

Findings

Analysis of multiple sites demonstrates strengths and limitations of current methods.

Assessment of data and models highlights gaps in understanding compound hazards.

Adaptation of North Atlantic methods shows potential for South Korean applications.

Abstract

Tropical cyclone-induced coastal hazards can significantly damage coastal infrastructure, and these risks may intensify under future climate change. As a result, there is increasing interest in conducting comprehensive assessments of coastal hazards-including storm surge, storm wind, storm rainfall, and their combined impacts-associated with tropical cyclone events. Risk assessments that overlook the compounding nature of these hazards may lead to ineffective or insufficient mitigation strategies. This study seeks to identify and evaluate the available data, models, and methodologies for assessing both individual and compound typhoon-induced hazards in South Korea. Particular effort is devoted to exploring how established approaches from the North Atlantic region can be adapted, integrated, and extended for application in the South Korean context. Multiple sites across South Korea are analyzed to illustrate the strengths and limitations of these methods.
