Sponsored by the Urban Water Resources Research Council and the Environmental and Water Resources Institute of ASCE. This book contains 29 selected papers dealing with urban water resources selected from more than 40 years of materials prepared by the Urban Water Resources Research Council (UWRRC). Members of the UWRRC have collaborated to prepare reports, technical memoranda, conference proceedings, and other documents and, in the process, made extraordinary contributions to the field of urban water resources planning, design, and management. This book documents the unique contributions of the UWRRC with papers that are as timely and provocative today as when they were first published. Readers will be struck by the foresight and perspective of UWRRC members on such subjects as drainage and flood control, stormwater quality management, water supply planning, risk assessment, public involvement and participation, and the role of the water engineer in society. This book presents the evolution and primary underpinnings of urban stormwater management and will be beneficial to all stormwater management professionals.

Proceedings of the Ninth International Conference on Urban Drainage, held in Portland, Oregon, September 8-13, 2002. Sponsored by Urban Water Resources Research Council of the Environmental Water Resources Institute of ASCE; International Association for Hydraulic Research; Joint Committee on Urban Drainage of the International Water Association. This collection of 329 papers presents state-of-the-art solutions to common urban storm drainage problems, such as flooding, combined sewer overflows, nonpoint-source runoff quality, urban streams, and more. Papers report on practical applications of new and traditional methods of analysis, design, construction, operation, and maintenance of urban storm drainage systems, as well as on institutional and educational approaches for improving the urban water environment. Topics include: best management practices; decision support and modeling; combined sewer overflows and sanitary sewer overflows; stormwater management; urban streams; monitoring; precipitation and hydrology; flooding; education and involvement; sewer processes; hydraulics; real-time control; and Portland, Oregon, wet weather.

Recent years have seen a very marked increase in the desire to protect the environment from any and all malign influences. The maintenance or restoration of water quality is a vital part of that protection. A sine qua non of control system development for modern sewer networks is therefore the preservation of the water system around a network’s outflow(s). Several approaches have been proposed for the optimisation of sewage control and Optimal Real-time Control of Sewer Networks provides a comparative synthesis of a central sewer network flow control based on two of these: nonlinear-optimal and multivariable-feedback control. In nonlinear optimal control, control and operational objectives are treated directly by the formulation of a nonlinear cost function minimized according to system constraints and the relevant state equation. The comparison presented uses the rolling horizon method for the real-time application of the optimal control algorithm with updated inflow predictions and updated initial conditions. On the other hand, the linear multivariable feedback regulator – considered with and without feedforward terms to account for external inflows – is developed via a systematic linear-quadratic procedure including precise specifications on model structure, equations and the choice of nominal steady state and quadratic criterion. The comprehensive testing and comparison of these protocols is undertaken on the basis of their respective control results for the real large-scale sewer network located around the river Obere Iller in Bavaria. The control strategies now implemented within this network are based on this study. Starting at the selection of possible methods of control and moving to the actual implementation of those methods in a real sewer system, Optimal Real-time Control of Sewer Networks will be invaluable to control and civil engineers working in sewage flow and wastewater treatment and of great interest to academics wishing to see how their ideas on optimal control are likely to work out when practically applied. Advances in Industrial Control aims to report and encourage the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.
