Error propagation for velocity and shear stress prediction using 2D models for environmental management.

Wheaton, Joseph; Buckland, E. M.; Pasternack, G. B.; Gilbert, A. T. (2006-08-30)

Resource managers, scientists, government regulators, and stakeholders are considering sophisticated numerical models for managing complex environmental problems. In this study, observations from a river-rehabilitation ...
Evaluating short-term changes in recreational water quality during a hydrograph event using a combination of microbial tracers, environmental microbiology, microbial source tracking and hydrological techniques: A case study in Southwest Wales, UK

Wyer, Mark D.; Kay, David; Watkins, John; Davies, Cheryl; Kay, Chris; Thomas, Rod; Porter, Jonathan; Stapleton, Carl M.; Moore, Heather (2010-09)

Quantitative assessment of multiple sources to short-term variations in recreational water quality, as indexed by faecal indicator organism (FIO) concentrations, is becoming increasingly important with adoption of modern ...
Farmyards, an overlooked source for highly contaminated runoff

Francis, Carol; Kay, David; Watkins, John; Edwards, Anthony C.; Wilkinson, J. R.; McDonald, Adrian T.; Wyer, Mark D. (2008-06)

Summer sampling of storm runoff generated from areas of roofs and hardstanding situated on four dairy/beef farms has provided novel information regarding its microbiological and chemical quality. All farm hardstandings ...
Floodplain catastrophes in the UK Holocene: messages for managing climate change

Macklin, Mark G.; Lewin, John (2011-06-13)

Floodplains may be transformed when environmental changes or human activity causes alluvial systems to cross channel pattern thresholds. Thresholds between pattern states based on occurrence fields are only available for ...
Flow convergence routing hypothesis for pool-riffle maintenance in alluvial rivers

Wheaton, Joseph; MacWilliams, M.; Pasternack, G. B.; Kitanidis, P. K. (2006-10)

The velocity reversal hypothesis is commonly cited as a mechanism for the maintenance of pool-riffle morphology. Although this hypothesis is based on the magnitude of mean flow parameters, recent studies have suggested ...
Formal ratification of the Quaternary System/Period and the Pleistocene Series/Epoch with a base at 2.58 Ma

Gibbard, P. L.; Walker, Michael J. C.; Head, M. J. (2009)

In June 2009, the Executive Committee of the International Union of Geological Sciences (IUGS) formally ratified a proposal by the International Commission on Stratigraphy to lower the base of the Quaternary System/Period ...
Formal ratification of the Quaternary System/Period and the Pleistocene Series/Epoch with a base at 2.58 Ma

Gibbard, P. L.; Head, M. J.; Walker, Michael J. C. (Wiley InterScience, 2010)

In June 2009, the Executive Committee of the International Union of Geological Sciences (IUGS) formally ratified a proposal by the International Commission on Stratigraphy to lower the base of the Quaternary System/Period ...

Griffiths, H. M. (2008-05-01)
Geomorphic dynamics of floodplains: ecological implications and a potential modelling strategy

Hughes, F. R. M.; Brasington, James; Richards, Keith S. (2002)

1. The dynamics of channel migration and floodplain renewal constitute an important control of the ecological diversity of river corridors. Restoration initiatives should therefore assess whether these dynamics must be ...
A geomorphological approach to the management of rivers contaminated by metal mining

Bird, Graham; Macklin, Mark G.; Brewer, Paul A.; Hudson-Edwards, K. A. (2006-09-30)

As the result of current and historical metal mining, river channels and floodplains in many parts of the world have become contaminated by metal-rich waste in concentrations that may pose a hazard to human livelihoods and ...
Heavy metals in potable groundwater of mining-affected river catchments, northwestern Romania

Bird, G.; Macklin, M. G.; Brewer, P. A.; Zaharia, Sorin; Balteanu, Dan; Driga, Basarab; Serban, Mihaela (2009-12-01)

Groundwater, accessed using wells and municipal springs, represents the major source of potable water for the human population outside of major urban areas in northwestern Romania, a region with a long history of metal ...
Holocene flood histories in south-western USA

Harden, Tessa; Baker, Victor R.; Macklin, Mark G. (2010-05-01)

River basins in south-western USA are some of the most extensively studied arid land fluvial systems in the world. Since the early 1960s their hydro-climatic histories have been reconstructed from the analysis of alluvial ...
Holocene flooding and river development in a Mediterranean steepland catchment: The Anapodaris Gorge, south central Crete, Greece

Macklin, M. G.; Tooth, S.; Brewer, P. A.; Noble, P. L.; Duller, G. A. T. (2010-02-01)

Many Mediterranean steepland rivers are flanked by extensive alluvial and colluvial deposits, but Late Quaternary histories of channel and hillslope behaviour remain poorly constrained, primarily because of the limited ...
Holocene land-use change and its impact on river basin dynamics in Great Britain and Ireland

Macklin, Mark G.; Foulds, S. A. (2006)

River basins in Great Britain and Ireland have been characterized by periods of hillslope and valley floor instability during the Holocene, reflecting sensitivity to both climate change and anthropogenic disturbance. In ...
Holocene sequences and archaeology from the Crabble Mill site, Dover, UK, and their regional significance

Bates, M. R.; Preece, R. C.; Barham, A. J.; Walker, M.; Whittaker, J. E.; Pedley, M.; Parfitt, K.; Parfitt, S.; Jones, S. (2008)

The results of multidisciplinary investigations of the Quaternary sediments of the Dour valley, extending inland from Dover, Kent, are reported. The oldest sediments are unfossiliferous coarse gravels and silts of probable ...
How sensitive are river systems to climate and land-use changes? A model-based evaluation

Macklin, Mark G.; Coulthard, Tom J. (2011-07-18)

Simulated Holocene sediment discharges from a high-resolution cellular model of river evolution in northern England, driven by a peat-bog proxy climate and palynological based land-cover record, show a very close similarity ...
The impact of future climate change on seasonal discharge, hydrological processes and extreme flows in the Upper Wye experimental catchment, mid-Wales

Jones, Tony; Pilling, C. G. (2002-04-30)

Analysing the impact of future climate change on hydrological regimes is hampered by the disparity of scales between general circulation model (GCM) output and the spatial resolution required by catchment-scale hydrological ...
The impact of recent climate change on flooding and sediment supply within a Mediterranean mountain catchment, southwestern Crete, Greece

Maas, G. S.; Macklin, Mark G. (2011-10-18)

This paper presents work from a geomorphological investigation carried out in the Aradena Gorge, southwestern Crete, Greece. The gorge is typical of many steepland fluvial systems in the Mediterranean, with steep relief, ...
In-situ characterization of grain-scale fluvial morphology using Terrestrial Laser Scanning

Hodge, Rebecca A.; Richards, Keith S.; Brasington, James (2009-04-14)

The grain-scale morphology of fluvial sediments is an important control on the character and dynamics of river systems; however current understanding of its role is limited by the difficulties of robustly quantifying field ...
Integrating agent-based models of subsistence farming with individual-based forest models and dynamic models of water distribution

Bithell, Mike; Brasington, James (2009-02)

Subsistence farming communities are dependent on the landscape to provide the resource base upon which their societies can be built. A key component of this is the role of climate and the feedback between rainfall, crop ...
