Results in brief
A probabilistic decision framework for MULti-HAzard RESilience of residential building portfolios subjected to floods and landslides
Floodings and landslide events (such as mudflows) are the most frequent natural disasters provoked by heavy rainfalls. Their occurrences often cause significant physical damage to the built environment, leading to severe economic losses and social disruptions in communities. To promote disaster resilience of communities, sophisticated models are needed to support citizens in making risk-based decisions on disaster mitigation actions. Considering the impacts of floodings and mudflows on the European residential community, the EU-funded MulHaRes project aimed to develop a decision-making approach that first establishes models to estimate physical hazard impacts on residential buildings; and then performs benefit analyses on hazard-retrofit options to find the optimal solutions for minimizing these associated impacts. In conclusion, the developed approach gives reliable resulting models that make "holistic" impact estimates on typical EU residential buildings under flood and mudflow actions, considering potential damage on "any building item and content item" and their associated "uncertainties." Moreover, the developed models distinguish differences in impact estimates and decision actions between "individual buildings" and "building portfolios". Therefore, the project outcomes can be widely used by research agencies, practitioners, and academicians seeking to address public policy issues related to the impacts of natural hazards and public investments in hazard-risk mitigation. Moreover, the project outcomes are of commercial value. They can be adapted to use by any EU country to develop insurance models, especially in the lack of any collected field data. Lastly, this fellowship helped the researcher Dr. Derya Deniz fully integrate into the host institution Ozyegin University, and supported her in making a significant career advancement and establishing an internationally well-recognized academic career in this research area.

Project objective
The recent catastrophic flood and landslide events triggered by heavy rainfalls have shown how vulnerable communities can be to natural disasters. To mitigate the impacts of natural disasters on communities, disaster resilience assessment and planning are required for the built-environment. The proposed research aims to develop a decision framework to support multi-hazard resilience of residential building stocks under rainfall-triggered floods and flow-type landslides (i.e., debris, mud-flows), considering two refinement levels in the framework: individual buildings vs. building portfolios in a community. The effects of uncertainties and spatial correlations in hazard demand and common building configurations and practices will be reflected in an aggregated assessment of multi-hazard resilience of building portfolios. The building portfolios that will be focused in the proposed methodology are residential buildings within a typical EU community, considering residential construction practice in Europe. However, the proposed framework can be adapted for resilience assessment and planning for other building portfolios involving different occupancies. The fellow Dr. Deniz, with her research experience in community disaster resilience and her firm-background in civil engineering, and reliability and statistical tools, has the required technical expertise to achieve the goal by conducting state-of-the-art robust analyses for the proposed project “A probabilistic decision framework for MULti-HAzard RESilience of residential building portfolios subjected to floods and landslides”. The proposed decision framework will greatly contribute to different stakeholders seeking to find optimal mitigation strategy for homes and to improve insurance portfolio risk policy, public policy and disaster management plans. This fellowship will support Dr. Deniz to establish an internationally well-recognized academic career and become one of the leading people on this particular research.
