- Abstract
Flooding is an annual problem in the Peusangan River Basin, Aceh. Flooding caused by overflowing Peusangan River results in environmental damage and significant economic losses for local communities, especially downstream. To mitigate these impacts, flood control measures are needed to reduce flood peaks. The purpose of this study was to determine the locations of retention ponds and river normalization and to determine their effects on the inundation area and floodwater level. To support this planning, this study used the Hydrologic Engineering Centers River Analysis System (HEC-RAS) 2D software to design and model flood control structures. The modeling was carried out by designing eleven retention ponds and implementing river normalization at three locations. The total retention pond capacity is 192,743,450 m3. Meanwhile, the total length of the river normalization was 5,522 meters. The modeling results indicate that the area of the village affected by flooding before the control structures were installed was 30.359 km2. After handling the scenarios of constructing retention ponds, river normalization, and a combination of the two, the inundation area decreased to 18.843 km2, 29.265 km2, and 17.310 km2 respectively. This indicates a decrease in the area of villages affected by flooding by 10%, 15%, and 9% respectively, compared to the initial condition of 16%. The water level in the retention pond scenario and the combination of the two decreased from 1.39 meters to 0 meters. Meanwhile, in the river normalization scenario, the WSE decreased to 1.19 meters.
