ESTIMATING CONTAMINANT LOADS IN RIVERS
1. Purpose and objectives
To review mass load estimation procedures and to recommend methods
to improve the accuracy of load estimates.
This component is a report containing a review of the methods most
commonly employed in river load estimation based principally on key papers
and reports. This is introduced by a brief explanation of some of the
terms and concepts involved in error analysis and a definition of
interpolation and extrapolation methods. Other topics covered in this
review include transfer function models, flow proportional and probability
sampling, real-time updated stratified sampling and hydrograph separation
This report also illustrates how a computer program for data
generation might be used to help solve the problem of the lack of long time
series of flow and concentration data. As an example, the use of a
There is a section on UK databases concerned with river quantity and quality, and one on UK river load surveys.
The report concludes with recommendations and suggestions for further
work relating to the topics discussed.
