Residential areas with the high rainfall intensity, flow pattern, and channel condition caused recurrent inundation flood in West Aceh Regency, Aceh Province, Indonesia. The inundation results in the physical damages to the housing components and the number of losses. This study aimed to devise the flood inundation map. The method was field survey to identifying the location, the inundation depth, and the conditions of the exposed residential in 20-24 September 2018. The results showed that the pattern of land flow and drainage conformed with the topography of the area. However, the channel condition, such as bushes, narrowing of the channel, and certain stations with low contoured, caused the vulnerability of inundation. The results showed that the area of the inundation was 26.66 Ha when the flood reached a maximum water level. The inundation varied in the study area, with a duration of 4 to 5 days. Forty housing units in different areas were exposed to the inundation flood, with varying damage conditions depending on the flood depth. It depended on the water depth of the flood. This approach can be a guideline for designing flood disaster mitigation strategies, especially for the elements of residential areas.

印度尼西亚亚齐省西亚齐县，降雨强度高、水流模式和渠道条件高的居民区导致洪水泛滥。淹没导致外壳部件的物理损坏和损失的数量。本研究旨在设计洪水淹没图。方法是在2018年9月20-24日通过实地调查确定暴露住宅的位置、淹没深度和状况。结果表明，土地流向和排水模式符合该地区的地形。但河道条件，如灌木丛、河道变窄和某些站台等高线低，造成了洪水泛滥的脆弱性。结果表明，当洪水达到最高水位时，淹没面积为26.66公顷。研究区的洪水泛滥不同，持续时间为 4 至 5 天。不同地区的 40 个住宅单元暴露在洪水中，根据洪水深度的不同，损坏情况也各不相同。这取决于洪水的水深。这种方法可以作为设计防洪减灾策略的指南，特别是对于住宅区的元素。
