natural rivers hydromorphological quality and river restoration a challenging new agenda for applied Fluvial Geomorphology
Earth Surface Processes and Landforms, 2006Co-Authors: Malcolm Newson, Andrew R G LargeAbstract:Fluvial Geomorphology is rapidly becoming centrally involved in practical applications to support the agenda of sustainable river basin management. In the UK its principal contributions to date have primarily been in flood risk management and river restoration. There is a new impetus: the European Union's Water Framework and Habitats Directives require all rivers to be considered in terms of their ecological quality, defined partly in terms of ‘hydromorphology’. This paper focuses on the problematic definition of ‘natural’ hydromorphological quality for rivers, the assessment of departures from it, and the ecologically driven strategies for restoration that must be delivered by regulators under the EU Water Framework Directive (WFD). The Habitats Directive contains similar concepts under different labels. Currently available definitions of ‘natural’ or ‘reference’ conditions derive largely from a concept of ‘damage’, principally to channel morphology. Such definitions may, however, be too static to form sustainable strategies for management and regulation, but attract public support. Interdisciplinary knowledge remains scant; yet such knowledge is needed at a range of scales from catchment to microhabitat. The most important contribution of the interdisciplinary R&D effort needed to supply management tools to regulators of the WFD and Habitats regulations is to interpret the physical habitat contribution to biodiversity conservation, in terms of ‘good ecological quality’ in rivers, and the ‘hydromorphological’ component of this quality. Contributions from ‘indigenous knowledge’, through public participation, are important but often understated in this effort to drive the ‘Fluvial hydrosystem’ back to spontaneous, affordable, sustainable self-regulation.

sediment related river maintenance the role of Fluvial Geomorphology
Earth Surface Processes and Landforms, 1995Co-Authors: David Sear, Malcolm Newson, A. BrookesAbstract:This paper addresses the role that Fluvial Geomorphology might play in the management of sediment-related river maintenance in the U.K. Sediment-related river maintenance refers to the operational requirement of river management authorities to remove deposits of sediment or protect river boundaries from erosion, where these compromise the flood defence levels of service. Using data collected as part of a National Rivers Authority (NRA) Research and Development Project it is possible to identify the geomorphic causes of problems, and engineering responses to sediment-related river maintenance (SRRM) in England and Wales. The Project identified the management problem as widespread and often treated in isolation from the causative processes. Geomorphological guidance is shown to be both relevant and complementary to conventional engineering practice through its ability to identify the cause of a SRRM problem. A methodology for conducting a geomorphological survey, or ‘Fluvial audit’, is presented, which synthesizes historical data on the catchment land-use and channel network, with contemporary morphological maps to present a statement of the location and type of sediment supply, transport and storage within the river basin under scrutiny. The application of Geomorphology to two contrasting SRRM problems is explored using case studies from two catchments: the River Sence, a fine sediment system, and the Shelf Brook, a coarse sediment system.

Applying Fluvial Geomorphology to river channel management: Background for progress towards a palaeohydrology protocol
Geomorphology, 2008Co-Authors: K.j. Gregory, G. Benito, Peter W. DownsAbstract:Significant developments have been achieved in applicable and applied Fluvial Geomorphology as shown in publications of the last three decades, analyzed as the basis for using results of studies of environmental change as a basis for management. The range of types of publications and of activities are more pertinent to river channel management as a result of concern with sustainability, global climate change, environmental ethics, ecosystem health concepts and public participation. Possible applications, with particular reference to river channel changes, include those concerned with form and process, assessment of channel change, urbanization, channelization, extractive industries, impact of engineering works, historical changes in land use, and restoration with specific examples illustrated in Table 1. In order to achieve general significance for Fluvial Geomorphology, more theory and extension by modelling methods is needed, and examples related to morphology and process characteristics, integrated approaches, and changes of the Fluvial system are collected in Table 2. The ways in which potential applications are communicated to decision-makers range from applicable outputs including publications ranging from review papers, book chapters, and books, to applied outputs which include interdisciplinary problem solving, educational outreach, and direct involvement, with examples summarized in Table 3. On the basis of results gained from investigations covering periods longer than continuous records, a protocol embracing palaeohydrological inputs for application to river channel management is illustrated and developed as a synopsis version (Table 4), demonstrating how conclusions from geomorphological research can be expressed in a format which can be considered by managersThe support of INQUA for research including development of a Protocol is gratefully acknowledged and the helpful comments from two referees.Peer reviewe

Fluvial Geomorphology: A perspective on current status and methods
Geomorphology, 2008Co-Authors: V.r. Thorndycraft, G. Benito, K.j. GregoryAbstract:Fluvial Geomorphology seeks to study river landform history, understand formative processes, and predict changes using a combination of field observation, experimental studies and numerical models. A resurgence in Fluvial Geomorphology is taking place, fostered for example by its interaction with river engineering, and the availability of new analytical methods, instrumentation and techniques. These have enabled development of new applications in river management, landscape restoration, hazard studies, river history and geoarchaeology. This paper presents a perspective on recent advances in Fluvial Geomorphology, and introduces a selection of papers presented during the Fluvial Geomorphology and Palaeohydrology session within the Sixth International Conference on Geomorphology held in Zaragoza (Spain) in September 2005.Peer reviewe

Fluvial Geomorphology of central and southern England
Fluvial Geomorphology of Great Britain, 1997Co-Authors: K.j. Gregory, R. J. DavisAbstract:The boundary between the ‘Highland Zone’, of the north and west of Britain, and the ‘Lowland Zone’, of the south and east, is usually taken as a line running approximately from the mouth of the River Exe to the mouth of the River Tees. The area defined here as central and southern England includes some portions of the Highland Zone. These are principally found in south-west England, where three upland plateau areas of western Cornwall rise above a landscape that is dominated by coastal low plateaux cut across resistant Palaeozoic rocks. Also representing the upland scenery and resistant rock theme of the Highland Zone are the Mendips and the Quantocks, although the limestone features of such areas as the Mendips are included in another volume in this series. The central and southern Pennines also have the relief, scenery and resistant rock outcrops characteristic of the Highland Zone.

An introduction to the Fluvial Geomorphology of Britain
Fluvial Geomorphology of Great Britain, 1997Co-Authors: K.j. GregoryAbstract:Scenery in Britain is closely associated with rivers. Because no area is very far from the sea there are no very large rivers, but since the country includes areas with more than 1000 mm of precipitation annually (Figure 1.1), there are large numbers of rivers and streams. The Thames has the largest drainage basin with an area of 9950 km2, but this is only 0.14% of the area of the world’s largest river basin, the Amazon. Although the Thames is the largest British river, according to drainage basin size and also according to length of the main river (239 km), it is not the largest British river according to mean annual flow. The Tay in Scotland has a mean flow 2.26 times greater than that of the Thames, and the flows of the Trent, the Ness, the Tweed and the Wye are also greater than that of the Thames.
