CASE03

Flood risk

Estimating flooding status from observation information

Functions to use	Flood Flows Run a river flooding simulation by inputting the observed information under flow conditions.
Required Information	Past flood information Observing position Observation information
Setting details	Observing position It is assumed that there is observation information on “Bishnumati Bridge” in Kathmandu, Nepal.
Setting details	Observing position Input CSV file Input the CSV file of observation information of time changes. Please refer to the sample file for the CSV file. Tips: Since rivers cannot be precisely expressed using topography alone, accuracy can be improved by specifying the time change of the ‘Surge’ function as the water level.

CASE04

Draft plan

Consideration of flood countermeasures due to river flooding

Functions to use	Flood Flows We will confirm the risk of inundation due to river flooding and confirm the effectiveness of countermeasures such as setting up an embankment on the left bank.
Required Information	Past flood information Current flood risk information Flood countermeasure plan
Setting details	Current flood risk information Use the simulation results of Case3 Tips: It is also very effective to use the results of replicating past flood damage.
Setting details	Flood countermeasure plan 5m embankment will be built to prevent flooding on the left bank.
