The origin of this research unit is Anti-Flood-Hazard Systems Research Division (established in 1982), which was restarted and renamed as Urban Flood Hazard in Bay Area Research Division in 1992. The establishment of the research unit was motivated by the imminent need of development of defensive measures against urban flood damage at that time. The urban flood damage and defensive measures became a prominent problem in conjunction with the residential developments in the mountain side areas, low wetlands and landfill sites, as well as the expansion of urban areas and the concentration of social and economic activities in densely populated cities located in the bay areas. The urban flood hazard was seriously recognized as a result of the following affecting factors:
 Increased vulnerability of urban systems to natural disasters
Degradation of internal and external disasters due to river floods, storm surges, tsunamis and high sea waves in urban areas
Changes in boundary and environmental conditions of the coastal area, such as sea level rise and landfill
The mission of the research division in the earlier years was to conduct basic research to establish a comprehensive disaster prevention / reduction system consisting of both hardware and software aspects, incorporating disaster prevention facilities, assessment of hazardous areas, appropriate land-use policy, alert and evacuation methodology etc.
With the reorganization of DPRI in 1996, the research unit was restructured as Research Section of Urban Flood Control under Fluvial and Marine Disasters Research Division, and with the DPRI reorganization in 2005, the it became a part of Research Center for Fluvial and Coastal Disasters. With the reorganization of 2024, it has become Research Section of Urban Compound Disaster Protection as a part of Research Division of Atmospheric and Fluvial-Coastal Disasters until the present day. Currently, the research unit has been developing research activities related to the following research topics.
Elucidation of flooding and flood damage and development of analytical models in highly developed and multilayered urban areas including buildings, road and sewage networks, underground commerce centers, subway and other underground spaces
Development of prediction analysis method and countermeasure for tsunami flooding and tsunami run-up to the urban areas
A method of prediction, prevention and mitigation of diverse and complex disaster processes in urban ares
Development of design and maintenance method of infrastructure and facilities for urban disaster prevention
Evaluation and control of dynamically coupled response of fluid / structure system
