Flood modelling in riverine floodplain areas
The number of people living close to rivers and within floodplain areas are growing rapidly worldwide, and recent years have proven a significant increase in frequency and severity of flood events in river systems globally. This creates a major threat to a growing number of people and their property.
Riverine flooding is caused by bank overtopping when the flow capacity of rivers is exceeded locally. The rising water levels generally originate from heavy snowmelt or high-intensity rainfall creating soil saturation and large runoff - locally or in upstream catchment areas. Sudden dam breaks or embankment failures are also important causes of flooding, and the severity may be further increased by local rising groundwater after prolonged natural recharge.
Riverine flood modelling with MIKE FLOOD combines our river model component, MIKE 11, and our 2D surface modelling component, MIKE 21. You can also conduct riverine modelling with detailed hydrological components and groundwater and surface water interaction using our MIKE SHE package. This includes a surface flood component and a linkage to MIKE 11.
Our riverine flood modelling packages serve as important analysis and planning tools to assist you with:
- Enhanced knowledge on impacts of riverine flood events
- Obtaining scenario analysis tools for improved flood alleviation
- Conducting accurate analysis of flood protection measures efficiency
- Providing seamless options for multiple flood scenario analyses, including impact assessment of climate change scenarios
- Seamless mapping of flood extent, flood risk and flood hazard
- Integrated modelling of catchments, rivers and floodplains
- Visualisation of flood dynamics in rivers and floodplains
- Extendable solution allowing analysis of riverine flooding impact on urban or coastal areas
