Abstract: In order to study the response to urban waterlogging disaster, determine the flood material preparedness standard and formulate emergency plans, the inundation range and depth and water volume of key areas are obtained by establishing the rainwater waterlogging dynamic model and analyzing the results of the rainwater waterlogging model. According to the above data, appropriate flood materials and evacuation plans for people in affected areas should be provided to scientifically reduce the losses caused by extreme natural disasters.
