Predictive Hydrology: A Frequency Analysis Approach is the first book to address both the theoretical concepts and the methodological approaches used in frequency hydrology. Spelling out fundamental methods, it providing concise instruction on the techniques that are involved and includes examples and critiques based on practical applications. Exploring recent research developments, the book targets students in civil engineering, environmental sciences and technology, hydrology, geography, geology, and ecology. It will also serve as a useful reference for teachers, researchers, and engineering practitioners who handle data, but often find themselves without the appropriate analytical tools.
