Flooding has become one of the most dangerous hydrometeorological disasters, affecting the sustainability of cities in the future. This study aims to assess flood susceptibility using a frequency ratio approach and evaluate the spatial planning in Pekanbaru City, Indonesia. Flood locations were derived from synthetic aperture radar data to prepare actual flood data. In this area, the identification of physical environmental parameters was conducted using various datasets such as slope, landform, curvature, topographic wetness index, distance from rivers, rainfall, soil texture, and soil depth. Furthermore, a weighted assessment of all thematic layers was calculated based on the frequency ratio of actual flood events in the observation area. The overall data related to the location of the events were divided, with 70% for model development and 30% for validation. The results showed that actual flood events affected 18 km², with an accuracy of 84.21%. Flood susceptibility was categorized into four levels such as very high (11.36%), high (58.04%), medium (24.78%), and low (5.81%). An accurate assessment of potential flood susceptibility, measured by the operational characteristic curve (AUC), showed a prediction rate of 76.30% and a success rate of 78.45%. However, considering the implications for spatial patterns, flood susceptibility affects cultivated areas covering 381.16 km², which are spread almost throughout the urban area. High to very high susceptibility areas indirectly cause disaster losses and impact community activities. The misalignment between the distribution of flood susceptibility and spatial planning in urban areas needs to be addressed to anticipate other potential hazards.

This study examines how the locational characteristics of heritage sites influence their current flood risk in an urban environment under changing climate conditions. We studied 1620 heritage sites in the highly urbanized environment of Seoul, Korea; the study first quantified the flood risk of heritage sites, considering the topography and hydrological environment under 10-, 30-, and 50-year return periods of extreme precipitation scenarios. Terrain analyses were then applied to examine the physical locational characteristics of heritage sites related to flood susceptibility, with a literature review on the historical origin and human factors of each site. The evaluation of the location conditions of at-risk sites and their relationship with the construction period and type of heritage sites was conducted. The results show that the physical, political, economic, social, and cultural determinants of location varied depending on the construction period and heritage type, leading to the present spatial distribution of heritage sites. Specific sites in topographical knickpoints and lowlands near streams, which face additional hydraulic pressure and drainage issues from urban development, showed particularly high flood risks. By examining the interplay between historical, physical, and urban development factors, the research provides a holistic understanding of flood risks, essential for sustainable conservation strategies.
