Impact of Climate Change on Train Operation Control Due to Flooding in Urban Small-Medium Sized Rivers

Key Points

• The study aims to assess how climate change affects train operation regulations due to flooding in urban small-medium rivers.
• Examination of regulatory decision-making based on precipitation levels.
• Assessment of future changes using climate model precipitation outputs.
• Analysis focused on five specific bridge locations in urban small-medium rivers.
• Increased frequency of regulatory decisions expected, from 0.5 to 3 times per 20 years.
• Probability of regulatory rainfall events is projected to increase 1.6 to 4.2 times.
• Flow rates corresponding to current regulatory probabilities may increase by 1.4 to 2.2 times.
