“…2a and 2b. The small increases in TP concentration during these low magnitude runoff events, albeit over a high background concentration, is an example of transport limited P transfer at the catchment scale (Haygarth et al, 2004). A further pattern of chronic TP transfer at low flow was observed during six-and seven-day periods without rainfall during May and June, respectively.…”

A six-month series of high-resolution synchronous stream discharge and total phosphorus (TP) concentration data is presented from a 5 km 2 agricultural catchment in the Lough Neagh basin, Northern Ireland. The data are hourly averages of 10-minute measurements using a new bankside, automatic, continuous monitoring technology. Three TP transfer event-types occur in this catchment: (1) chronic, storm independent transfers; (2) acute, storm dependent transfers; (3) acute, storm independent transfers. Event-type 2 transferred over 90% of the total 279 kg TP load in 39% of the total period; it corresponded to diffuse transfers from agricultural soils. Event-types 1 and 3, however, maintained the river in a highly eutrophic state between storm events and were characteristic of point source pollution, despite there being no major industrial or municipal point sources. Managing P transfers at the catchment scale requires a robust monitoring technology to differentiate between dynamic, multiple sources and associated event types and so enable a reliable assessment of the performance of mitigation measures, monitored at catchment outlets. The synchronous and continuous TP and discharge data series generated in this study demonstrate how this is possible.

“…These processes group into either solubilisation or detachment mechanisms, defined by the physical size of the P compounds that are mobilised (Haygarth et al 2005). The detachment and transfer of non-dissolved P in association with soil particles is more pronounced where farming practices generate erosion (Chamber et al 2000) and provides a physical mechanism for mobilising P from soil into surface waters (Sharpley and Smith 1990;Toy et al 2002).…”

“…The delivery of these materials to hydrological networks is augmented by the relatively low filter resistance and restricted potential for temporary storage in these small catchments. Resultantly, the catchment export of sediment and P may be closely related to the magnitude of erosion and land degradation (Kovacs et al, 2012), with adverse impacts on the aquatic habitats ensuing (Collins and Walling, 2004;Haygarth et al, 2005a;Haygarth et al, 2005b;Holden et al, 2007;Valle Junior et al, 2015).…”
