ABSTRACT
Flood and social vulnerability analyses were used to assess the dynamics and social impact of flood in the flood plains of Tanay.  Flood simulation was carried out using the derived hydrograph as input in the simulation model.  The social vulnerability of each of the flood-prone barangays in the town was also determined using proxy indices such as strength of public infrastructure, demographic and socio-economic factors. The model successfully predicted the flood depths and delineated the spatial extent of flooding in the different barangays of the town. This was shown by the simulated flood depths that were comparable with the observed flood depths of the communities in seven out of nine flood-prone communities in Tanay. Barangay Tabing Ilog had the highest overall vulnerability index, indicating that this barangay is the most vulnerable to flood and needs a comprehensive flood risk preparedness and social development plan to increase the coping capacity of the residents to flooding.

INTRODUCTION
Many populations around the world are vulnerable to various disasters. During the 20th century, natural disasters particularly floods are occurring around the world with increased frequency and strength as a consequence of land-use changes and increased climate variability (Balica et al. 2009). In the Philippines, the intense and beyond-normal downpour of rainfall during Typhoon Ondoy last 2009 created devastating effects to life and properties and to the development of the affected areas in the low-lying areas of Metro Manila and Rizal Province. Losses suffered by these places were overwhelming and set back economic and social development (Pati et al. 2014). Rehabilitation costs were almost unaffordable and the affected individuals and families suffered psychologically and financially (Borga et al. 2011; Ouma and Tateishi 2014) . . . . . . read more
