Published by the American Geophysical Union as part of the Water Resources Monograph Series, Volume 7.This monograph has been written over the last 2 years by eight members of the AGU Urban Hydrology Committee as a means of conveying state-of-the-art practices in the expanding field of urban hydrology and stormwater management. Although numerous references to on-going research are cited, the monograph is intended to serve primarily as a practical guide to methods and models currently in use to analyze different types of stormwater management problems. With this objective in mind, the authors have made a special effort to include examples which help illustrate the steps in a particular procedure or analysis. The monograph presumes a basic background in hydrology and makes no real effort to present conventional procedures which can be found readily in available hydrology textbooks. However, the detailed example calculations in Chapters 2, 3, and 4 should assist the unfamiliar reader in understanding basic hydrologic computations related to urban rainfall-runoff analysis. Given this coverage, the monograph should be useful as a reference to practicing engineers and urban planners as well as to graduate students in engineering-environmental disciplines with career interests in the growing field of urban hydrology and stormwater management.
