The flood was so big that it entered people's homes with a flood height of 60 cm to 100 cm. The flood had a rather severe impact in several villages, mainly Polando Jaya Village, Lalundu Utama Village, Panca Mukti Village, Rio Mukti Village, Pakava Village, Ngovi Village, Pantolobete Village, Bonemarawa Village, and Tinauka Village. Based on these problems, the purpose of this study was to determine the level of flood vulnerability using GIS in Rio Pakava District, Donggala Regency.This research was conducted for three months, starting from January to March 2022, with quantitative methods by means of scoring and weighting. Scoring and weighting are carried out on several parameters, namely rainfall, slope, soil type, land use, and river density.The results obtained in the Lariang Hulu watershed area, Rio Pakava District, Donggala Regency, the category prone to flooding is 1,410.10 Ha or 4.08%, the category is quite prone to flooding 9,621.01 Ha or 27.09%, the category is somewhat vulnerable to 23,561.01 Ha or 68.09% , and the category not vulnerable 10.05 Ha or 0.03% . |
