| dc.description.abstract | Flooding is the inundation of a place due to high rainfall and causes an overflow of water
that exceeds the water disposal capacity of an area and causes economic, social and
physical losses. This research is motivated by the condition of the drainage and rivers in
Paluh Kemiri Village/Subdistrict which cannot accommodate the large amount of incoming
discharge due to high rainfall at the end of the year.
This study aims to obtain and determine the potential for flood inundation in the Paluh
Kemiri Village/District area with a flood inundation map produced from the Hydrologic
Engineering Center - River Analysis (HEC-Ras) software with the Environmental
Protection Agency Storm Water Management Model (EPA SWMM).
In carrying out this study, data was collected which included geometric data, rainfall data
from BMKG, and land use data. The Log Pearson III method fulfills the requirements for
rainfall frequency distribution. Next, flood discharge calculations were carried out using
the Rational Method for return periods of 5, 10, 25, 50 and 100 years. After that, channel
capacity discharge calculations were carried out using the R. Manning Method. From the
results of manual calculations, analysis of flood inundation in drainage using the
Hydrologic Engineering Center - River Analysis (HEC-Ras) software and the
Environmental Protection Agency Storm Water Management Model (EPA SWMM)
software, it can be seen that there is flood inundation at return periods 25, 50 and 100 year.
The location of the floodwaters is in the drainage on Jalan Ahmad Yani, Jalan Walet, Jalan
Inpres SD, Jalan Sudirman, Jalan Gg Front Polres/Jalan Kuburan, and Jalan LP. And the
drainage location where no puddles occur is the drainage on Jalan Malinda and on Jalan
Sudirman. For the estimated loss due to flood disasters with a return period of 5, 10, 25, 50
and 100 years, it is IDR. 23,179,816,552. | en_US |
