A Case Study on Simulation of Urban Inundation by Inland Flooding and River Flooding

Sangho Lee, Taeuk Kang, Yongkyu Jin, Donggyu Hwang

J. Korean Soc. Hazard Mitig. 2023;23(5):31-42.

Urban flooding can occur due to a combination of factors such as insufficient drainage capacity in stormwater systems, inland flooding from elevated river levels, and river flooding. This study proposes a method for analyzing urban inundation resulting from these complex phenomena using XP-SWMM. This is essentially a model capable of...

Short-term Prediction of Urban Inundation based on Radar-predicted Rainfall through Real-time SWMM Parameter Calibration

Woojin Lee, Gyujin Park, Jongwon Choi, Hwandon Jun

J. Korean Soc. Hazard Mitig. 2023;23(5):43-54.

In recent times, the rapid pace of climate change has been causing urban inundation in areas where drainage of inland water is difficult. In response to this concern, studies that use SWMM are being actively conducted to predict urban inundation. However, the parameters applied to SWMM use historical values, resulting...

Analyzing Downstream Flooding Effects Due to Small-Scale Reservoir Destruction Using Flow-R

Hayong Kim, Yoonkyung Park, Jingul Joo

J. Korean Soc. Hazard Mitig. 2023;23(5):55-62.

The frequency of abnormal weather patterns owing to climate change and the aging of reservoirs are contributing to an increase in dam failures, particularly of small-scale agricultural reservoirs. Dam collapses can lead to significant human and material damage downstream, even in the case of small-scale reservoirs. Therefore, alongside systematic maintenance...

Study on Fire-Resistance Performance and Heat-Discharge Characteristics Based on the Thickness of Plant Concrete Barriers

Yichul Shin, Daehoi Kim, Sooyoung Park

J. Korean Soc. Hazard Mitig. 2023;23(5):87-93.

Fire-resistant barriers are usually installed in industrial plants to reduce the risk in fire. These barriers are installed in accordance with the guidelines stipulated in various standards applicable to the plant, but the standards for fire-resistance performance and barrier thickness are unclear. In this study, fire-resistance tests were conducted on...
