“…Compared to agricultural and forested landscapes, relatively few studies have quantitatively determined the sources of sediment in urban waterheds with studies to date being concentrated in Australia (e.g., Ormerod, 1999;Charlesworth et al, 2000), Brazil (e.g., Poleto et al, 2009;Franz et al, 2014), China (e.g., Yin and Li, 2008), UK (e.g., Charlesworth et al, 2000;Carter et al, 2003) and USA (e.g., Devereux et al, 2010). In part this stems from the inherent hydrological complexities associated with urban areas, alongside multiple diffuse sediment sources, and the potential for transformations in the physical and chemical properties of the sediment (Taylor and Owens, 2009).…”

“…The high contribution of urban sources (up to 40% sewage and RDS) illustrates the marked contrast of urban sediments to those in non-urbanised river basins. Yin and Li (2008) used a similar approach using 7 Be and 210 Pb as tracers to estimate that about 60% of the suspended sediments at the outlet of a sewer system in Wuhan City, China was derived from the drainage system (gutter sediments and combined sewer sediments), with about 40% from RDS. These findings are in general agreement with Nelson and Booth (2002) who found that, as well as landslides and channel bank erosion, 15% of sediment in an urbanised catchment was from road surface erosion.…”

“…Urban systems may exhibit a 'first-flush' or 'initial micro-pulse' (Lee et al 2002;Lawler et al 2006;Yin and Li 2008) whereby there is an initial increase in the sediment flux (concentration and/or load) due to a coupling between urban sources (i.e. RDS, CSO delivery) and the urban river network by rain events.…”

Background, aim and scope Over 50% of the global population live in urban centres and, therefore, an understanding of the processes acting upon urban systems is a global issue. The nature of human-made, often impervious, land surfaces and heavily engineered waterways results in hydrological and sedimentological systems in urbanised basins which contrast significantly to those within more natural (i.e. pristine, forested, agricultural) aquatic systems. In addition, the abundance of contamination sources in urban systems results in chemical pressures often manifested as high pollution concentrations or loadings, which in turn have detrimental impacts on human and ecosystem health. These lead to management and sustainability issues not generally encountered in more natural environments. The purpose of this review is to provide a state-of-the-art assessment of sediment sources, pathways and storage within urban river systems, to consider sediment management within urban systems and river basins, and examine the role of local and global environmental changes on sediment processes and management. Inevitably, much of the sediment that is transported within urbanised basins is contaminated, so this review also considers sedimentcontaminant sources and interactions. Conclusions and recommendationsWe reach a number of conclusions and recommendations for future research. There is a need for better sampling and monitoring of sediment and sediment-associated contaminant fluxes and cycling in urban river channels and basins. This should include better techniques and studies to identify sources and transfers of road-deposited sediment (RDS), airborne particulate matter and sediments in the river system. Greater interdisciplinary research, combining sedimentologists, hydrologists, urban planners, urban archaeologists, chemists and biologists, is needed. More attention needs to focus on upscaling and connecting urban areas to the rest of the river basin, both upstream and downstream. Finally, there is a need to balance multiple needs (urban population, water resources) with likely trends in both urban development and global environmental change.Keywords Contaminants . River basin . Sediment . Sediment management . Urban . Urbanisation Background, aim and scopeAt the time of writing, over 50% of the global population live in urban centres, with this value set to increase (UNFPA 2007). Thus, for example, about 80% of the UK population live in conurbations, and even in a large, relatively unpopulated country such as Canada about 70% of the population live in urban areas. In addition, the number of 'mega-cities' (those cities with a population of greater than 10 million) is also increasing, particularly in the developing world: China, India and South America. Therefore, an understanding of the processes acting upon

“…Lee and Heaney [19] about 52 years of long-term rainfall data to demonstrate that imperviousness of the surface is an important indicator of the impact of urbanization on stormwater systems and has a direct influence on stormwater quality and quantity. Identification of SS sources in urban stormwater runoff using radioactive tracers ( 7 Be and 210 Pb) was done by Yin and Li [20]. They found that 60±12% of SS at the sewer outlet originated from the drainage system sediments while the rest was from the wash-off of urban ground dust during the rainfall events.…”

Stormwater runoff from urban and suburban areas generates numerous pollutants. The areas include residential areas, parks, commercial areas, industrial areas and road/highways. Land use and human activities largely determine the nature and level of pollutants. Among the various types of pollutants that can contribute to adverse water quality impact in receiving water bodies, of concern are suspended solids, heavy metals, polycyclic aromatic hydrocarbons and nutrients. This paper provides a critical review of the characteristics and sources of urban stormwater pollutants and the manner in which the pollution occurs. Treatment systems for urban stormwater runoff and for urban stormwater harvesting are discussed.
