- Abstract
Flooding has become an increasingly urgent global issue, causing environmental damage and significant economic and social losses. Over the past ten years, Nagan Raya Regency has experienced 24 flood events that have caused casualties and damage to residential houses. To mitigate the risk of damage and losses caused by flooding, it is necessary to carry out flood control measures. The objective of this study is to assess the impact of flood control modeling, including levee construction and river normalization, on water surface elevation and flood inundation area downstream of the Tripa River Basin, as well as to plan appropriate locations for flood control structures. The research method involves hydraulic modeling using the Hydrologic Engineering Centers River Analysis System (HEC-RAS) version 6.6 software. The modeling plan includes levees at six locations with a total length of 9,008 meters, revetments at three locations totaling 1,347 meters, and normalizing the river at five locations spanning 9,848 meters. The modeling results indicate that after implementing the flood control structures, the flood inundation area for the 25-year return period decreased from 108.35 km2 to 105.58 km2 or about 2.6%. Although the reduction in the inundation area is relatively small, the number of flood inundation points in the study area dropped significantly from 29 points to only 3 points, representing an 89% decrease. Additionally, the flood water levels at two points in Kabu Village and Lueng Kuebue Jagat Village also declined, from 1.82 meters to zero and from 1.64 meters to 0.77 meters, respectively.
