The number of phosphorus loss events will increase with variability and seasonality in far future climate scenarios.

ABSTRACT: Climate change is likely to add further pressures to water quality degradation across the globe. The development of robust climate-smart mitigation measures necessitates understanding the impact of extreme hydrological events on catchment hydrology and nutrient losses. Here, empirical modelling (EM) was applied on 14 years of sub-hourly water quality and weather data from six hydrologically diverse agricultural catchments in Ireland to understand the climatic factors that trigger an increase in phosphorus (P) losses [manifested as increase of 0.01 mg L^- 1 in total phosphorus (TP) and increase of 0.005 mg L^- 1 in total reactive phosphorus (TRP) over one day]. Plausible future P-loss due to extreme weather events was then modelled using climate change scenarios (from 20
