CASE05

Urban flood

Consideration of flood countermeasures due to short-term heavy rains

Functions to use

Rainfall

We will confirm the risk of flooding due to short-term heavy rains and consider rainfall standards for drainage measures.

Required
Information

Past flood information
  • Rainfall information
  • Drainage planning rainfall

Setting details

Rainfall information

Input the hourly rainfall of the future climate change scenario confirmed with ’show rainfall’ in the urban area of Hue, Vietnam.

Tips:
Enter the amount of rainfall for which you need to consider countermeasures, such as the maximum observed amount of rainfall.
Drainage planning rainfall

Assuming that the target rainfall for the drainage facility is 50mm, we set 73.8mm by subtracting 50mm from the target rainfall of 123.8mm.

FUTURE

CASE06

Coastal flood

Consideration of flood countermeasures due to sea level rise in coastal areas.

Functions to use

Surge embankment

We will confirm the risk of flooding due to sea level rise in coastal areas and consider the effectiveness of coastal embankment measures.

Required
Information

Past flood information
  • Tide information
  • Coastal embankment planninginformation

Setting details

Tide information

Select the coastal area of Funafuti in Tuvalu, enter the future sea level height of 1m and the initial value of 10h for time information.

Tips:
The simulation time is specified as 2 hours because the calculation range is narrow. If flooding is expected over a wide area, such as in a plain area, it is necessary to set a long time.
Tips:
You can also enter the height of waves caused by storm surge. In that case, by setting the ‘type’ item to ‘Time invariant’, you can set tide level changes that change over time.
Coastal embankment planning information

Confirm that two areas are flooded and create a 3m embankment on the coast to check the effectiveness of the measures.
