The objective of street stormwater drainage design is to warrant efficient and safe traffic movements during the severe storm events. This book is dedicated to the latest developments in: (a) new concepts to analyze the urban catchment hydrology for storm runoff predictions, (b) innovative methods to estimate the street allowable capacities to convey storm runoff, and (c) useful computer models to simulate flow movements in inlets and sewers. • An excellent textbook for senior designs in Civil Engineering • A useful technical book for Public Works and Urban Infrastructure, • Good reviews of street hydraulics for Urban Drainage • Revised Rational Method for urban catchment analysis, • New concepts of street flow modeling with consideration of safety, • Improved methods for street inlet sizing and storm sewer designs, and • Efficient computer programming and models for sewer system flow analyses, and • Excel tools using Excel spreadsheets and workbook approaches.
