Zusammenfassung |
Ten methods for estimating the loads of constituents in a river were tested
using data from the River Don in North-East Scotland. By treating loads derived
from flow and concentration data collected every 2 days as a truth to be
predicted, the ten methods were assessed for use when concentration data are
collected fortnightly or monthly by sub-sampling from the original data.
Estimates of coefficients of variation, bias and mean squared errors of the
methods were compared; no method consistently outperformed all others and
different methods were appropriate for different constituents. The widely used
interpolation methods can be improved upon substantially by modelling the
relationship of concentration with flow or seasonality but only if these
relationships are strong enough. |
