This book, first published in 1987, contains a collection of papers presented at the 18th Binghamton Symposium, focusing on the topic of catastrophic flooding. These papers make the case for the careful collection and interpretation of data from which the importance and effects of catastrophic flooding may be deduced. Questions tackled include: what are the causes and effects of catastrophic flooding? What parameters should be used to measure them? What effect do they have on erosional and depositional landforms? Can modelling be used to predict their flow dynamics?
