Flood Modelling of the Effect of Tide Fluctuations in Malusac, Sasmuan, Pampanga

Abstract

The Philippines' geographic location, which faces the Pacific Ocean and is part of the Pacific Ring of Fire, contributes to its vulnerability to natural catastrophes, particularly floods and other hydrological events. Every year, the country is hit with a lot of storms and rain, which can create flooding in a lot of places, especially around the shore. Rising sea levels increase the risk of flooding, and coastal communities must prepare for this increased risk [1]. Storm events that frequently flood many coastal communities are worsened by sea level rise and climate change. A crucial, but often ignored, aspect of the recurring floods these areas experience is the elevation of the groundwater table in these low-relief coastal cities [2]. In order to solve the growing problem of flooding in Malusac, Sasmuan, Pampanga, a model projecting the different flood effects by the varying tides was created in this study. Also, to be prepared and provide data that will aid the community in dealing with the coastal flood. The methods used were the collection of data including the elevation, boundary, location of the study area and maps, particularly the geologic, vicinity and land use map. All the data were obtained at the Municipality of Sasmuan, Pampanga, namely the Department of Engineering, Municipal Planning & Development Coordinator, and Municipal Disaster Risk Reduction and Management Office. The data gathered will be inputted into ArcScene and ArcMap to run and create the model. At the end of the study, the researchers will also provide a Flood Response Framework to help the community.
