Floods are one of the natural disaster leading couse of economic loses and death in the word. From 1970 to 2011 more than 60 timr of floods were reported in the US, Brazil, China, Thailand, and Indonesia (EM-DET, 2011). The number of death descreased significanly to 10.000 people death in 1960s after hitting a high of 210.000 peple in 1950s,.

Accourdingly, Tangerang City as a suburna area of Jakarta, faced that impact. Thopographical, characteristics, meteorological characterstics, and antrhropology in this research was based on GIS computation of the frequent rainfall inundation areas in tangerang between 2008 and 2015. The frequenrainfall inundation record from Tangerang City Government and a 90-an m Merit DEM bu Yamazaki 2017) were used in this research.
