Research Activity

URBAN FLOOD CONTROL

The main research objective is how to prevent or reduce urban flood disasters. Mechanism and prediction method of flood disasters in urban area are studied. Countermeasures against urban flood are also examined. The specific research topics are as follows:

  1. Mechanism of urban flood disasters due to heavy rainfall, river flood, storm surge or their combination.

  2. Numerical modeling and analysis of inundation flow behavior in urban area considering buildings, streets and underground space effects.

  3. Design and evaluation of both structural countermeasures(such as underground tunnel systems) and nonstructural ones(such as evacuation systems).

  4. Numerical modeling and analysis of flow behavior and sediment transport in an estuarine basin.

  5. Flood hazard analysis in river recreation site due to heavy rainfall.

  6. Urban disasters caused by Tsunami and their modeling.
