| Zusammenfassung |
| High-resolution measurements of total phosphorus (TP) concentrations in a
stream draining a 5 km2 agricultural catchment (a sub-catchment of Lough
Neagh in Northern Ireland) were made every 10 min by continuous flow
instrumentation using new homogenisation, digestion and colorimetric phases.
Concurrently, rainfall and stream discharge data were collected at 5 and 15
min intervals. Major P flushing episodes during storm events peaked on the
rising limbs of storm hydrographs. A period of baseflow also indicated the
importance of other sources that maintain the stream in a eutrophic state
between storm events. These data provide insights into catchment processes
that conform to definite patterns that, in a coarser sampling regime, might
ordinarily be attributed to sampling and analytical "noise". |
