This book summarises for the first time all relevant methodologies for type-based flood statistics, introduces the basis of flood typology and makes them accessible to the user. Flood types improve the understanding of the flood-generating processes and characterise the flood event in terms of its features such as peak, volume and hydrograph shape. In addition, they can also significantly expand the information used in flood statistics and add valuable flood characteristics to the determination of design floods, especially the determination of flood scenarios relevant for reservoir management. A detailed framework with all aspects of point and spatial statistics as well as regionalisation is presented, and examples illustrate the benefit of the proposed methodology. The target audience is both users in associations and engineering offices, as type-based statistics are increasingly becoming part of the specifications, and researchers, as this is a current field of research.

Summarizes the methodology of type-based flood statistics Contains detailed examples that help the reader to understand the methodology Includes a thorough framework for all aspects of design flood estimation

Autorentext

Andreas H. Schumann studied Hydrology and water management at the Technical University in Dresden, Germany. After his PhD in 1981 he worked several years in different water management agencies. In 1989 he went back to academia and became a Senior-Lecturer at the Ruhr-University in Bochum, Germany. In the year 2001 he became a Full Professor for Hydrology and Water Management at this university. Many of his scientific activities were dedicated to flood research. He published more than 200 papers and is the editor of the book "Flood Risk Assessment and Management", published by Springer in 2011. After retiring in 2019, he is researching as a Senior-Professor at the Ruhr-University. He initiated the Research Unit "Space-time Dynamics of Extreme Floods" (SPATE) which was funded by the German Research Foundation from 2017 to 2023. Svenja Fischer studied mathematics at the Ruhr-University in Bochum, Germany, and holds a PhD in statistics from the Technical University of Dortmund. Since 2021, she is an assistant professor for stochastic hydrology at the Ruhr-University Bochum. Her scientific activities focus on flood research with special emphasis on flood frequency analyses. She has published more than 30 papers, was vice-president of the IAHS commission for statistical hydrology (ICSH) from 2019 till 2023 and received the Tison award from IAHS in 2021 for her research paper on flood types.
