Risk Evaluation of Ice Flood Disaster in the Upper Heilongjiang River Based on Catastrophe Theory

“…Ice-jam floods often cause issues such as farmland submersion, building collapse, and embankment erosion. Additionally, these disasters can also affect the sedimentation and release of chemical substances in river water bodies [4,5]. Thus, ice floods are more likely than open-water floods to cause financial costs and damage to humans and their habitats [6].…”
