Chemical Oxygen Demand as a Measure of Fluvial Organic Matter Oxidation State (2023)
Journal Article
Worrall, F., Clay, G. D., Howden, N. J. K., & Burt, T. P. (2023). Chemical Oxygen Demand as a Measure of Fluvial Organic Matter Oxidation State. Journal of Geophysical Research: Biogeosciences, 128(10), Article e2022JG007248. https://doi.org/10.1029/2022jg007248

The oxidative ratio (OR) of the terrestrial biosphere is directly related to the size of the terrestrial biosphere carbon sink. In turn, OR of naturally occurring organic matter can be directly related to the oxidation state of the carbon in naturall...

Brief reference is necessarily made to some research from before and after t... Read More about Slopes: solute processes and landforms.

Constraining the Carbon Budget of Peat Ecosystems: Application of Stoichiometry and Enthalpy Balances (2022)
Journal Article
Worrall, F., Boothroyd, I. M., Clay, G. D., Moody, C. S., Heckman, K., Burt, T. P., & Rose, R. (2022). Constraining the Carbon Budget of Peat Ecosystems: Application of Stoichiometry and Enthalpy Balances. Journal of Geophysical Research: Biogeosciences, 127(10), https://doi.org/10.1029/2022jg007003

We consider how the stoichiometry and energy content of organic matter reservoirs and fluxes through and from a peatland enable the fluxes and storage of carbon within a peatland to be constrained. We include the elemental composition of the above- a... Read More about Constraining the Carbon Budget of Peat Ecosystems: Application of Stoichiometry and Enthalpy Balances.

Is water quality in British rivers “better than at any time since the end of the Industrial Revolution”? (2022)
Journal Article
Whelan, M., Linstead, C., Worrall, F., Ormerod, S., Durance, I., Johnson, A., …Tickner, D. (2022). Is water quality in British rivers “better than at any time since the end of the Industrial Revolution”?. Science of the Total Environment, 843, Article 157014. https://doi.org/10.1016/j.scitotenv.2022.157014

We explore the oft-repeated claim that river water quality in Great Britain is “better now than at any time since the Industrial Revolution”. We review available data and ancillary evidence for seven different categories of water pollutants: (i) bioc...

A 50‐Year Record Of Nitrate Concentrations In The Slapton Ley Catchment, Devon, United Kingdom (2021)
Journal Article
Burt, T., Worrall, F., Howden, N., Jarvie, H., Pratt, A., & Hutchinson, T. (2021). A 50‐Year Record Of Nitrate Concentrations In The Slapton Ley Catchment, Devon, United Kingdom. Hydrological Processes, 35(1), Article e13955. https://doi.org/10.1002/hyp.13955

Slapton Ley, a coastal lake, is the largest natural body of fresh water in south‐west England. There was concern in the 1960s that the lake was becoming increasingly eutrophic. To quantify inputs of water, sediment and nutrients into the lake, Slapto... Read More about A 50‐Year Record Of Nitrate Concentrations In The Slapton Ley Catchment, Devon, United Kingdom.

The problem of underpowered rivers (2020)
Journal Article
Worrall, F., Burt, T. P., Hancock, G. R., Howden, N. J., & Wainwright, J. (2020). The problem of underpowered rivers. Earth Surface Processes and Landforms, 45(15), 3869-3878. https://doi.org/10.1002/esp.5007

This study has hypothesized that for many rivers the trade‐off between flow accumulation and the decrease in slope along channel length means that stream power increases downstream and, moreover, that given the low slope angles in headwater and low‐o...

Monitoring soil erosion on agricultural land: results and implications for the Rother valley, West Sussex, UK (2020)
Journal Article
Boardman, J., Burt, T., & Foster, I. (2020). Monitoring soil erosion on agricultural land: results and implications for the Rother valley, West Sussex, UK. Earth Surface Processes and Landforms, 45(15), 3931-3942. https://doi.org/10.1002/esp.5011

Monitoring has played a key role in understanding the rates, extent and frequency of erosion on agricultural land and this includes projects in Switzerland, Germany and the UK. In this case we focus on highly erodible soils in the Rother valley, West...

A spatial total nitrogen budget for Great Britain (2020)
Journal Article
Fan, X., Worrall, F., Baldini, L. M., & Burt, T. P. (2020). A spatial total nitrogen budget for Great Britain. Science of the Total Environment, 728, Article 138864. https://doi.org/10.1016/j.scitotenv.2020.138864

Understanding nutrient budgets makes it possible to predict where and by how much nutrients are accumulating in the environment. Previous studies have considered this problem for nitrogen (N) but have limited themselves to reactive N species (i.e. ex... Read More about A spatial total nitrogen budget for Great Britain.

The importance of sewage effluent discharge in the export of dissolved organic carbon from United Kingdom rivers (2019)
Journal Article
