Abstract :
January 2021 Floods hit South Kalimantan
in 10 cities, and floodwaters inundated at least 24,379
houses. The government of South Kalimantan
announced Emergency Status for Flood Disasters a day
after water washed that region on January 15, 2021. This study intends to model the distribution of high
inundation that occurs using the Storm Water
Management Model (SWMM) and also aims to obtain a
Priority Analysis based on the impact of inundation that
occurs by referring to the Procedure of Compiling a
Master Plan for Urban Drainage Systems from the
Directorate General of Human Settlements, Ministry of
Public Works and Housing. The research location is in
the SimpangLayang and Veteran Flood Control Area
(FCAs), East Banjarmasin, with an area of 2,078,740 ha.
From the nine modeled Sub-Systems, the average
flood inundation height in the Simpang Layang FCA is
about 0.886 m. The average inundation height for the
Veterans FCA is about 0.838 m from the eight modeled
Sub-Systems. This modeling obtained 195 points of
inundation that occur in both FCA. Recommendations
will be made for Priority Analysis of the Control Flood
Inundation to validate the data on the distribution of
inundation points. This study took five validation points:
Jl Ayani, Komplek Kenanga, Komplek Smanda III, Jl
Mahat Kasan, and Jl. Pramuka. Jl. Pramuka is the
location with the highest priority, assessed based on
inundation parameters, economic losses, social
disturbances, government facilities, transportation
disturbance losses, housing losses, and
personal/household property rights losses. The area with
this highest priority number requires forward mitigation
because this area has been most severely affected and
inundated for a long time. This area is also one of the
centers of government, economic commodities, various
companies, health center facilities, residential and public
transportation centers in Banjarmasin, and other public
facilities.
