This section is composed of three basic subareas: combined sewer overflows (CSOs), sanitary sewer overflows (SSOs), and stormwater discharges. Much of the literature cited came from documents covering noteworthy global conferences (Bathala, 1996; Engineering Foundation, 1996; Hallam et al., 1996; Maxwell et al., 1996; Sieker and Verworn [Eds.], 1996; Society of Environmental Toxicology and Chemistry, 1996; U.S. EPA 1996a; Water Environment Federation, 1996a,b,c). In addition, the U.S. Environmental Protection Agency (U.S. EPA) published guidance documents (U.S. EPA, 1996,c,d,e), which are discussed in more detail in the subsection Regulatory Policies and Financial Aspects.

Urban wet-weather flows

Turbidity dynamics during spring storm events in an urban headwater river system: the Upper Tame, West Midlands, UK.

Prediction of changes to in-stream ecology are highly desirable if decisions on river management, such as those relating to water abstractions, effluent discharges or modifications to the river channel, are to be justified to stakeholders. The physical habitat simulation (PHABSIM) system is a well-established hydro-ecological model that provides a suite of tools for the numerical modelling of hydraulic habitat suitability for fish and invertebrate species. In the UK, the most high-profile PHABSIM studies have focused on rural, groundwater-dominated rivers and have related to low flow issues. Conversely, there have been few studies of urban rivers. This paper focuses on the application of PHABSIM to urban rivers and demonstrates how sensitivity analyses can be used to assess uncertainty in PHABSIM applications. Results show that physical habitat predictions are sensitive to changes in habitat suitability indices, hydraulic model calibration and the temporal resolution of flow time-series. Results show that there is greater suitable physical habitat over a wider range of flows in a less engineered river channel when compared to a more engineered channel. The work emphasizes the need for accurate information relating to the response of fish and other organisms to high velocities. Copyright © 2004 John Wiley & Sons, Ltd.

Application of physical habitat simulation (PHABSIM) modelling to modified urban river channels

The widespread degradation of lotic ecosystems has prompted extensive river restoration efforts globally, but many studies have reported modest ecological responses to rehabilitation practices The functional properties of biotic communities are rarely examined within post-project appraisals, which would provide more ecological information underpinning ecosystem responses to restoration practices and potentially pinpoint project limitations This study examines macroinvertebrate community responses to three projects which aimed to physically restore channel morphologies Taxonomic and functional trait compositions supported by widely occurring lotic habitats (biotopes) were examined across paired restored and non-restored (control) reaches The multivariate location (average community composition) of taxonomic and functional trait compositions differed marginally between control and restored reaches However, changes in the amount of multivariate dispersion were more robust and indicated greater ecological heterogeneity within restored reaches, particularly when considering functional trait compositions Organic biotopes (macrophyte stands and macroalgae) occurred widely across all study sites and supported a high alpha (within-habitat) taxonomic diversity compared to mineralogical biotopes (sand and gravel patches), which were characteristic of restored reaches However, mineralogical biotopes possessed a higher beta (between-habitat) functional diversity, although this was less pronounced for taxonomic compositions This study demonstrates that examining the functional and structural properties of taxa across distinct biotopes can provide a greater understanding of biotic responses to river restoration works Such information could be used to better understand the ecological implications of rehabilitation practices and guide more effective management strategies

Macroinvertebrate Taxonomic and Functional Trait Compositions within Lotic Habitats Affected By River Restoration Practices

Urban riverscapes represent some of the most heavily engineered and degraded freshwater ecosystems in the world, and offer limited opportunities for restoration or rehabilitation because of continued anthropogenic use. The future of maintaining biodiversity and ecological quality in anthropogenic ecosystems may rest with the incorporation of novel techniques for habitat creation and improvement into the management of such systems, to reconcile the ecological requirements of the ecosystem with anthropogenic resource use. This emerging field is termed ‘reconciliation ecology’ and its principles may be particularly relevant to urban riverscapes. This review firstly draws a distinction between river restoration and rehabilitation on the one hand and reconciliation ecology on the other, before reviewing key factors relating to possible habitat creation and improvement methods for heavily engineered urban riverscapes, within the context of reconciliation ecology. Examples are mainly drawn from the UK, but can have international applications. Although such methods are relatively unexplored at the present time, this represents a useful research area that may engender collaborations between restoration researchers and practitioners in urban regions.

Perspectives on the potential for reconciliation ecology in urban riverscapes

Experience and knowledge of river-restoration schemes are generally available at the reach scale. However, there are problems with the application of this knowledge at the scale of large urbanised catchments which relate to understanding the system and predicting the impact of management strategies. This paper considers problems of developing a perceptive and efficient rehabilitation strategy for a large urbanised catchment, with specific reference to the River Tame in the West Midlands. Consideration is given to (a) rainfall-runoff relationships, (b) assessment of water quality and ecological status, and (c) predicting the impact of various management strategies.
