INTEGRATED FLOOD MODELING FOR URBAN RESILIENCE PLANNING FOR MANDAUE CITY, PHILIPPINES

Urban flood resilience planning in the Philippines is necessary due to the country’s vulnerability to natural disasters and the effects of climate change, which increase the risk of flooding in urban areas. The high population density in urban cities further exacerbates this vulnerability making it crucial to have well-informed maps to serve as guides for disaster mitigation, prevention, and preparation. This study aims to create a 2D urban flood model for Mandaue City, Philippines integrating its urban aspects of road networks, drainage systems and other flood control structures to create a comprehensive hydrodynamic model. Data integration was created through Geographic Information System (GIS) and followed by 2D flood modelling in the Flo-2D program. The objective of the study aims to provide insights that can support the development of effective flood resilience planning. This planning will help prioritize tasks such as managing population growth, implementing measures to mitigate urban flooding, and integrating considerations of flood risks into urban development plans. Additionally, the results can help shed light into solutions to reduce the economic impact of flooding, ensure public health and safety, and foster environmental conservation. © 2023 ACRS.
