“…Therefore, this study proposed an analysis of inundation caused by erosion-induced defense malfunctions for two scenarios: One for the erosional coast sector, in which the 0 m isobaths are fixed by the coastal defense, and the other for the insufficient function of coastal defense regardless of the current state or erosion estimation. This study analyzed a scenario of coastal inundation induced by the malfunction of defense from coastal erosion in terms of the elevation difference between the heights of shoreland and 50-year tidal level recurrence periods, previously calculated as 2.64 m (Huang et al, 2018) [40], in order to analyze the significance of the inundation depth. For this analysis, the scope of coastal inundation was considered to be inherently compartmentalized by regional drainage due to the flood protection system.…”

A coastal erosion risk assessment was framed as the basis for the intervention of coastal adaptation strategies under time-variant scenarios. The framework was devised to assess the influence of coastal erosion on coastal defense, the coastal inundation induced by the erosion-induced malfunction of defense, and risks using a downscaling analysis and the mechanism of the compound hazard interaction, which are innovative and practical for the application of coastal management in Taiwan. In addition, the vulnerable socio-economy was also taken into consideration in risk assessment. The adaptive strategy is proposed in terms of the risk origins and time-variance of risk forecasts, and the risk origins were assessed based on the Fuzzy Delphi Method and the analytic hierarchy process instead of subjective consideration. Within the erosion-induced hazard and risk assessments, this study considered erosion rates, decreases in defense elevation due to land subsidence, and population development in time-variant scenario analyses to estimate risk forecasts. Furthermore, a case study of the Yunlin coastal area was undertaken to demonstrate the feasibility of the proposed method. The presented results are informative for coastal hazard reduction and the promotion of the sustainable development of coastal zones.

This paper intends to offer the readers an overview of the Special Issue on Coastal Vulnerability and Mitigation Strategies: From Monitoring to Applied Research. The main focus of this Special Issue is to provide the state-of-the-art and the recent research updates on the sustainable management strategies for protecting vulnerable coastal areas. Based on 28 contributions from authors from 17 different countries (Australia, China, Ecuador, Germany, Greece, India, Italy, Mexico, The Netherlands, New Zealand, Poland, Spain, Sri Lanka, Taiwan, United Arab Emirates, UK, USA), an ensemble of interdisciplinary articles has been collected, emphasizing the importance of tackling technical and scientific problems at different scales and from different point of views.

“…Sea-related hazards are mainly triggered by monsoons in winter and typhoons (tropical cyclones) in summer, including extreme waves (EW), storm surges, destructive swells, coastal flooding, and SST drop (SD; Doong et al, 2015;Hsu et al, 2015;Chen and Liu, 2016;Chang et al, 2018;Huang et al, 2020;Kuo et al, 2020). The potential risk maps for typhooninduced waves have been used to identify vulnerable areas along the coast of Taiwan (Chien et al, 2012;Huang et al, 2018;Shih et al, 2018). Taiwan is also located in an earthquake-prone area.…”

A service platform (referred to as Taiwan Marine Environment Monitoring Service) was designed to integrate marine environmental parameters, including wind, wave, tide, current and temperature components, from in-situ and remote sensing observations, ship reports and numerical models to support the safety of various marine-related activities in Taiwanese waters. Independent modules were developed and plugged into the platform to facilitate advanced analyses via the safe sea, particle tracking module, extreme waves, oil spill simulation, tsunami warning (TW), sea level rise, dangerous swell warning (DSW), and SST drop modules. This paper introduces the service platform and DSW and TW module analysis methods. A real-time analysis method for tsunami height is developed and validated; a criterial analysis of hazardous swells is also performed. This service platform is now in operation and has served more than 10 governmental institutions and numerous members of the public in Taiwan.
