The Indonesian Geographers Association HAZARD ASSESSMENT TO TIDAL FLOOD INUNDATION (Case Study: Tegal Municipality)

Tegal Municipality is one of coastal cities suffering from tidal flood inundation. This paper aims to assess current and future hazards to understand the extent of the inundation. Field observation, questionnaires, in-depth interviews, as well as secondary data collection have been great tools in achieving the research objectives. It is found that households in research location are dominated by low hazard indexes. The results are influenced both by current autonomous and planned adaptation strategies conducted by affected households and governments. It is also found that due to its relatively low-lying area, Muarareja is the first village affected by inundation depth increase. A 10 cm inundation depth scenario results in the inundation of more than 85 % of Muarareja’s total area. Meanwhile in Tegalsari, Mintaragen, and Panggung, a 10 cm inundation depth scenario results in inundation of less than 21 % of total areas
