This handbook approaches flood risk science from a problem-oriented and systems-based perspective, recognising flooding as a dynamic interaction between hydrological processes, landscape characteristics, and human interventions. It presents a layered understanding of how flood events emerge, evolve, and impact both natural and built environments. Rather than focusing solely on theoretical constructs, the book connects scientific reasoning with applied management practices, illustrating how data, modelling, and technological tools contribute to informed risk evaluation. It also highlights the significance of adaptive strategies, spatial planning, and infrastructure resilience in mitigating long-term impacts. Attention is given to the complexity of environmental variability and the need for integrated responses that balance ecological sustainability with socio-economic considerations. The narrative encourages readers to view flood management not merely as a technical challenge, but as a multidisciplinary and evolving field requiring continuous innovation.

This handbook is particularly suited to professionals, researchers, and advanced learners seeking a deeper, application-driven understanding of flood risk. It fosters critical thinking, strategic planning, and the ability to engage with real-world environmental uncertainties in a structured and informed manner.
