Modelling Sustainable Urban Drainage Structures

by Innovyze  (Jan. 1, 2002)

Introduction “Sustainable Development” is an increasingly important concept in most industries today, and one in which the water industry has been making rapid progress for over a decade. In countries around the world, including the USA, Europe, and Australia, Sustainable Urban Drainage (SUD) structures - permeable pavements, ponds, and the like ...

GIS applications in urban drainage master planning

by XP Solutions  (Mar. 2, 2012)

Introduction: The City of Stratford, Ontario, located 150 km (94 mi.) west of Toronto, initiated the development of an infrastructure asset database in the early 1990’s and continues to develop digital mapping to support the maintenance and management of municipal services. In continuing these efforts, the City initiated the City-Wide Storm ...

A spatial-temporal rainfall generator for urban drainage design

by IWA Publishing  (Jul. 4, 2013)

The work presented here is a contribution to the Thames Water project of improving the Counters Creek catchment sewerage system in London. An increase in the number of floods affecting basements in the area has indicated the need for improvements to the system. The cost of such improvements could be very high, and as such it is important to ...

A new litter trap for urban drainage systems

by IWA Publishing  (Feb. 1, 1999)

ABSTRACTLitter is generated in shopping areas and is washed or blown into stormwater drainage systems. These convey the litter to open water bodies leading to the accumulation of non-biodegradable litter on the banks and beaches of urban waterways and bay foreshores. The increasing public awareness of the problem prompted the State Government of ...

Implications of climate and urban development on the design of sustainable urban drainage systems (SUDS)

by IWA Publishing  (Oct. 23, 2012)

This paper explores the implications of climate change and urban development on the design of sustainable urban drainage systems (SUDS) using the example of ponds and raingardens in Auckland, New Zealand. Many of Auckland's coastal and freshwater receiving environments have been degraded due to stormwater inflows and are potentially at ...

Evolution of an integrated 1D/2D modeling package for urban drainage

by XP Solutions  (Mar. 2, 2012)

Introduction: Recent flooding events in North America have revealed deficiencies in existing stormwater infrastructure and management practices. The development of effective and efficient designs requires a comprehensive understanding of flooding in urban areas and complex open channel and overland flow systems. Traditional one dimensional (1D) ...

1D & 2D modelling of urban drainage systems using xpswmm and Tuflow

by XP Solutions  (Mar. 2, 2012)

Introduction: The release of a revised New South Wales (NSW) Floodplain Management Manual in 2001 established a new direction for urban flood management in NSW. This new direction was created by a redefinition of the floodplain as the area bounded by the Probable Maximum Flood (PMF) – this poses a challenge to estimate PMF flooding in highly ...

Use of InfoWorks CS to build an integrated urban drainage model

by Innovyze  (Feb. 28, 2008)

Creation of a single integrated InfoWorks CS model covering foul, surface and river systems is proving invaluable in understanding the complex interactions within a flood-prone urban catchment in north west London. The three systems had originally been held in separate models, with the foul and surface networks each modeled in InfoWorks CS and ...

Decision Analysis Applications for the Sustainability of Global Urban Water Resources and Drainage Systems

by Water Environment Federation (WEF)  (Oct. 22, 2006)

ABSTRACTWater is one of the most vital elements needed for life. In many countries water supplies, especially for critical drinking water, are either being depleted or polluted. Too often these problems are magnified due to the lack of reliable drainage systems that provide proper stormwater and sanitary sewage collection and treatment of human ...

The use of deconvolution techniques to identify the fundamental mixing characteristics of urban drainage structures

by IWA Publishing  (Apr. 1, 2010)

Mixing and dispersion processes affect the timing and concentration of contaminants transported within urban drainage systems. Hence, methods of characterising the mixing effects of specific hydraulic structures are of interest to drainage network modellers. Previous research, focusing on surcharged manholes, utilised the first-order ...
