Flood hazard mapping using Flo-2D to simulate the flood plain in a river basin.

 

Data used:
DEM
River Network
Land use and land cover data
Soil data
Rainfall data

 

Constructing the model involves:
Incorporating the collected data,
Defining the boundary conditions (upstream and downstream water levels) and initial conditions,
Setting model parameters like roughness coefficients and infiltration rates.

Simulating the Flood
Mapping the Hazard by analyzing the output data to determine the hazard levels.

 

The simulated flood extent was compare with field observation data for validation and accuracy assessment.
