Modelling faecal coliform dynamics in streams and rivers
TL;DR: In this article, a new conceptual model of faecal coliform dynamics is proposed and preliminary modelling results presented, based on the assumption that the entrainment and deposition of organisms from storage within the stream bed is governed by the relationship between flow and the channel bed.
Journal ArticleDOI
Cross continental increase in methane ebullition under climate change
Ralf Aben,Nathan Barros,Ellen Van Donk,Thijs Frenken,Sabine Hilt,Garabet Kazanjian,Leon P. M. Lamers,Edwin T. H. M. Peeters,Jan G. M. Roelofs,Lisette N. de Senerpont Domis,Susanne Stephan,Mandy Velthuis,Dedmer B. Van de Waal,Martin Wik,Brett F. Thornton,J. Wilkinson,Tonya DelSontro,Sarian Kosten +17 more
TL;DR: It is suggested that global warming will strongly enhance freshwater CH4 emissions through a disproportional increase in ebullition (6–20% per 1 °C increase), contributing to global warming.
Journal ArticleDOI
Faecal indicator organism concentrations in sewage and treated effluents
David Kay,J. Crowther,Carl Michael Stapleton,Mark D. Wyer,Lorna Fewtrell,Anthony C. Edwards,Carol Francis,Adrian McDonald,John Watkins,J. Wilkinson +9 more
TL;DR: Very marked, statistically significant reductions in GM FIO concentrations result from secondary and tertiary treatment, and there are statistically significant differences between some secondary and some tertiary treatments.
Journal ArticleDOI
Catchment microbial dynamics: the emergence of a research agenda
David Kay,Anthony C. Edwards,Robert C. Ferrier,Carol Francis,Christopher David Kay,L. Rushby,John Watkins,Adrian McDonald,Mark D. Wyer,John Crowther,J. Wilkinson +10 more
TL;DR: In the UK, the majority of catchment-scale activity in this field has been undertaken by physical geographers although microbial flux analysis and modelling has received much less attention from the research and policy communities than, for example, the nutrient parameters as mentioned in this paper.
Journal ArticleDOI
Faecal indicator organism concentrations and catchment export coefficients in the UK.
David Kay,J. Crowther,Carl Michael Stapleton,Mark D. Wyer,Lorna Fewtrell,Steven G. Anthony,M. Bradford,Anthony C. Edwards,Carol Francis,M. Hopkins,Christopher David Kay,Adrian McDonald,John Watkins,J. Wilkinson +13 more
TL;DR: Examples are presented to illustrate how the results can be used to estimate daily summer base- and high-flow FIO loads for catchments with different land use types, and to assess the likely effectiveness of certain strategies for reducing FIO pollutant loadings in areas with extensive areas of lowland improved pasture.
