Flood Modelling: From Catchment Analysis to Risk Mapping
Flooding is one of the major natural hazards that can affect residential areas, industrial developments, agricultural land, roads, drainage networks, and critical infrastructure. Rapid urbanisation, changing rainfall patterns, inadequate drainage capacity, and development in flood-prone areas can increase the potential impact of flood events. For this reason, understanding how water behaves during heavy rainfall and extreme flow conditions is important for safer planning and infrastructure development. Flood Modelling provides a scientific approach to analysing water movement, identifying vulnerable locations, and supporting effective flood risk management. What Is Flood Modelling? Flood Modelling is a technical process used to simulate how rainfall, runoff, and water flow behave across a defined geographical area. It combines information such as rainfall data, topography, drainage characteristics, river or stream conditions, land use, soil properties, and catchment behaviour to ...
