Abstract

Flood is one of the disasters that often hit various regions in Indonesia, specifically in West Kalimantan. The floods in Nanga Pinoh District, Melawi Regency, submerged 18 villages and thousands of houses. Therefore, this study aimed to map flood risk areas in Nanga Pinoh and their environmental impact. Secondary data on the slope, total rainfall, flow density, soil type, and land cover analyzed with the multi-criteria GIS analysis were used. The results showed that the location had low, medium, and high risks. It was found that areas with high, prone, medium, and low risk class are 1,515.95 ha, 30,194.92 ha, 21,953.80 ha, and 3.14 ha, respectively. These findings implied that the GIS approach and multi-criteria analysis are effective tools for flood risk maps and helpful in anticipating greater losses and mitigating the disasters.

基于GIS和多准则分析的南加比诺西加里曼丹地区洪水风险制图

洪水是经常袭击印度尼西亚各个地区的灾害之一，特别是在西加里曼丹。马拉维县南加比诺区的洪水淹没了18个村庄和数千所房屋。因此，本研究旨在绘制南加比诺的洪水危险区及其对环境的影响。利用多准则GIS对坡面、总降雨量、流量密度、土壤类型和土地覆盖等次生数据进行分析。结果表明，该地区有低、中、高风险。高、易发、中、低风险区分别为1515.95 ha、30194.92 ha、21953.80 ha、3.14 ha。这些结果表明，GIS方法和多准则分析是绘制洪水风险图的有效工具，有助于预测更大的损失和减轻灾害。
