Abstract:The causes and consequences of floods are embedded in complex sociopolitical contexts with numerous stakeholders of various interests and views that impact how problems are formed or perceived. Thus, the challenge of transferring the Dutch Room for the River (RftR) to other jurisdictions is not just about implementing technology, it requires a fundamental shift in the governance and culture. Through a technical analysis of flood modelling simulation and social assessment of applying flood resilience framework and contextual water governance theory, this study assesses how the stakeholders perceive the RftR approach and what is the feasibility of implementing the RftR intervention in Tsengwen River in Taiwan. The flood modelling is based on rainfall during Typhoon Morakot in 2009, which caused severe damage in southern Taiwan. The simulation shows an excellent performance (NSE = 0.938), and the flood characteristic analysis indicates that the Tsengwen Reservoir plays a crucial role in flood regulation in the Tsengwen River basin. In addition, the proposed interventions, including the RftR approach, optimised dam operation, and detention ponds, are simulated to evaluate the effectiveness of mitigating the flood hazards in the Danei District. Through applying the flood resilience framework, this study reveals that the current flood risk management strategies are biased towards building the resistance capacity to floods. This tendency might erode the flood resilience in the system. A contextual water governance theory is implemented to assess the complicated interaction among the actors, and how the cultural context, regulations, and previous projects shaped the Tsengwen River basin. These social assessments explicate how flood resilience and water governance framework could complement each other to provide an intact view of complex sociopolitical contexts. In conclusion, this study explores the possibility of applying the Dutch RftR approach to the water governance system in Taiwan. Gaining a better understanding of the viability of implementing the RftR approach in the Tsengwen River basin could help stakeholders in water governance anticipate and address potential challenges and conflicts that may arise when implementing RftR within unique political and geographical contexts.
