Flooding is the foremost natural hazard around the world, affecting human life and property (directly and indirectly). In the current era, many hydraulic and hydrologic modelling techniques are available for flood risk assessment and management as well as flood risk prevention and preparedness. They provide a platform for the scientific community to explore the causes of floods and to build up efficient methods for flood mitigation.

This special issue invites in-depth research work carried out through flood modelling including hydrological modelling, flood hydrodynamic modelling, flood inundation mapping, flood hazard mapping, risk assessment, flood policy, and flood mitigation strategy. It also welcomes studies dealing with various uncertainties associated with different stages of modelling and the exploration of modern techniques for model calibration and validation.

In addition, real-time flood inundation mapping is an important aspect for the evacuation of people from low-lying areas and reduction of the death toll. Real-time data gained through UAV-based flood inundation mapping and associated uncertainty in real-time aerial surveying are welcome in this special issue.
