Title: The River Thames phosphate model
Author: Gerrie Veldsink
Document Type: Monograph
Abstract:
A practical period for the Wageningen Agricultural University in Holland was fulfilled by working with The Water Quality Planning (WQP) Section in The National Rivers Authority (NRA) Thames Region. During the three months period from January '96 to March '96 a phosphate model for the River Thames has been used by WQP to determine whether phosphorus removal at sewage treatment works would have an effect on eutrophication, and to identity works where it would have the most impact. However, there appeared to be difficulties in calibrating and validating this model against data collected in the catchment of the River Colne, which is part of the Thames catchment. A more complex description of the catchment of the River Colne than being represented in the model could be an improvement. The objective of this practical period is to improve the calibration and validation of the River Thames Phosphate model for the River Colne. Also will be tried to improve the model by checking the order of Sewage Treatment Works and to try to bring high decay rates down in a number of sub-catchments.
