Book excerpt: Urban Stormwater Modeling and Simulation discusses several popular stormwater models and explains a variety of uses in practical terms. This unique book is divided into five key sections and begins with a description of urban runoff problems and how computer models play an important role in problem solving. The book continues with detailed discussions on the construction of watershed models, model verification and validation, the use of models for predicting stormwater runoff and pollution discharges, and common problems associated with popular modeling programs. A practical approach is used throughout the book, focusing on actual applications to illustrate basic principles. This is the first book available that provides both new and experienced engineers, consultants, and scientists with an organized approach to stormwater modeling and simulation, model construction, model verification, and software selection. Water quality professionals, environmental engineering students, technical libraries, regulators, and planners will also find this a perfect hands-on learning tool.
