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 ...

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 ...

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 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 ...

Impacts of climate change on rainfall extremes and urban drainage systems: a review

by IWA Publishing  (Jul. 4, 2013)

A review is made of current methods for assessing future changes in urban rainfall extremes and their effects on urban drainage systems, due to anthropogenic-induced climate change. The review concludes that in spite of significant advances there are still many limitations in our understanding of how to describe precipitation patterns in a ...

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 ...

Impacts of Climate Change on Rainfall Extremes and Urban Drainage Systems

by IWA Publishing  (Jun. 4, 2012)

Cities are becoming increasingly vulnerable to flooding because of rapid urbanization, installation of complex infrastructure, and changes in the precipitation patterns caused by anthropogenic climate change. While there are many previous works that have dealt with the effects of urbanization, the number of quantitative assessment studies related ...

Comparison between InfoWorks hydraulic results and a physical model of an urban drainage system

by IWA Publishing  (Jul. 19, 2013)

Urban drainage systems are frequently analysed using hydraulic modelling software packages such as InfoWorks CS or MIKE-Urban. The use of such modelling tools allows the evaluation of sewer capacity and the likelihood and impact of pluvial flood events. Models can also be used to plan major investments such as increasing storage capacity or the ...

Urban drainage models – simplifying uncertainty analysis for practitioners

by IWA Publishing  (Nov. 29, 2013)

There is increasing awareness about uncertainties in the modelling of urban drainage systems and, as such, many new methods for uncertainty analyses have been developed. Despite this, all available methods have limitations which restrict their widespread application among practitioners. Here, a modified Monte-Carlo based method is presented that ...
