Effective urban drainage to manage stormwater and control flooding depends on good engineering especially when an environmentally sustainable approach is being applied. This new text focuses on green methods and modelling techniques. It covers the principles of hydrology and drainage low-impact-development (LID) designs computer modelling techniques the evaluation of existing systems and planning for both new development and urban renewal. It outlines design procedures using examples spreadsheet models photos and real-world design examples. Unlike other books which focus on extreme events this book covers hydrologic designs for both extreme and frequent events and reflects the latest revolution in stormwater LID management and takes a quantitative as well as a qualitative approach. PowerPoint presentations and Excel computer models are provided to follow and build on the exercises in the book. It is written especially for students on urban watershed courses and also for those studying urban planning landscaping water resources hydrology and hydraulics. . Language: English
