The impact of climate change on groundwater recharge: National-scale assessment for the British mainland Open
Groundwater systems provide an important source of water supply as well as contributing baseflow to rivers, lakes and dependent ecosystems and so the impact of climate change on these systems needs to be understood. Calculating recharge to…

The need to integrate legacy nitrogen storage dynamics and time lags into policy and practice Open
Increased fluxes of reactive nitrogen (Nr), often associated with N fertilizer use in agriculture, have resulted in negative environmental consequences, including eutrophication, which cost billions of dollars per year globally. To address…

Assessing the vulnerability of shallow groundwater resources to deep subsurface energy activities (VoGERA) Open
<p>Society is increasingly looking to the subsurface for our energy needs, be that for extracting geothermal energy, shale gas, or buffering heat, gas, or storing by-products of energy production. An increasingly crowded subsurface p…

Developing a groundwater watch list for substances of emerging concern: a European perspective Open
There is growing concern globally about the occurrence of anthropogenic organic contaminants in the environment, including pharmaceuticals and personal care products. This concern extends to groundwater which is a critical water resource i…

Hydrological Outlook UK: an operational streamflow and groundwater level forecasting system at monthly to seasonal time scales Open
This paper describes the development of the first operational seasonal hydrological forecasting service for the UK, the Hydrological Outlook UK (HOUK). Since June 2013, this service has delivered monthly forecasts of streamflow and groundw…

The Nitrate Time Bomb (NTB) Model: a simple but effective method to investigate the impacts of historical nitrate loading on long-term groundwater nitrate concentrations Open
Nitrate water pollution, which remains an international problem, can cause long-term environmental damage and threaten both the economy and human health. Agricultural land is the major source of nitrate water pollution. It can take decades…

Quantification of nitrate storage in the vadose (unsaturated) zone: a missing component of terrestrial N budgets Open
National terrestrial nitrogen budgets for many developed countries have been calculated as part of the management of impacts of N on the environment, but these rarely represent the subsurface explicitly. Using estimates of vadose zone trav…
View article: The changing trend in nitrate concentrations in major aquifers due to historical nitrate loading from agricultural land across England and Wales from 1925 to 2150
The changing trend in nitrate concentrations in major aquifers due to historical nitrate loading from agricultural land across England and Wales from 1925 to 2150 Open
Nitrate is necessary for agricultural productivity, but can cause considerable problems if released into aquatic systems. Agricultural land is the major source of nitrates in UK groundwater. Due to the long time-lag in the groundwater syst…

Challenges of modelling a complex multi-aquifer groundwater system at a national scale: case study from the UK Open
Modelling of the UK groundwater system, composed of multiple discrete aquifers, is undertaken to help
\nassess water resources at the national scale. This groundwater system is made of the major aquifers that

Estimating numbers of properties susceptible to groundwater flooding in England Open
In the wake of widespread groundwater flooding that affected properties and infrastructure in southern England during 2014, a review has been undertaken of the number of properties in England that might be vulnerable during episodes of hig…
