Abstract: Sudden sinkhole events pose a threat to the property and life of citizens in large cities with dense social infrastructures. Sinkholes take place around the living areas of people due to sudden climate changes and urban development and there is a need to analyze and investigate them to make a total plan for urban disaster measures. This study set out to collect hydro-geomorphological information from sinkhole areas, analyze their characteristics from a hydro-geomorphological perspective with the Analytic Hierarchy Process (AHP) and GIS spatial analysis tools and identify sinkhole-prone areas. The study calculated the weighted rates of multiple factors identified before by applying the AHP theory. Based on the factors identified to evaluate sinkholes, the study selected and built spatial information including the sinkhole maps covering their locations. Such GIS spatial analysis techniques were used to obtain the analysis results of identified spatial information that reflected hydro-geomorphological characteristics. The findings led to the identification of sinkhole-prone areas from a hydro-geomorphological perspective. It was also found that adjacency, flow inclination of underground water and underground water levels of hydro-geomorphological factors turned out to have significant connections with sinkholes in the identified areas and that the possibility of sinkholes were high in non-residential areas. The spatial analysis with GIS produced the results shown in the risk of sinkholes in figure which categorized the risk of sinkholes into A, B, C and D for spatial presentation. Category A accounted for 27% which means that it was very vulnerable to sinkholes from a hydro-geomorphological perspective. The study analyzed the hydro-geomorphological characteristics of multiple factors of sinkholes with the GIS analysis technique and found that the risk of sinkholes was high around residential areas and in the roads, thus, raising a need for the urban facility management agencies to manage sinkholes systematically. In addition, the urban administration staff needs to conduct analysis and research on sinkholes by making active use of GIS and upgrade and apply the risk index of sinkholes on an ongoing basis based on the results. These findings may serve as major, basic data in the fields of urban disaster prevention and urban planning in the future and raise a need for extended research to integrate the field of facility management.
