Abstract:
The principal objective of this study was to compare estimates of load based on discrete data (grab samples and instantaneous measurements of flow) with those based on continuous monitoring. Subsidiary objectives were to demonstrate the effects of sampling frequency and of choice of method of calculation on the accuracy of estimates, and to check the validity of sampling from a single position in the cross-section of the river.
