Title: The 1990 river and estuary classification survey of England and Wales
Author: National Rivers Authority Anglian Region
Document Type: Monograph
This present report comprises comprehensive guidelines which NRA Regions must follow in order to achieve the requirements of the 1990 Survey of rivers and estuaries. Methods are specified for chemical and biological sampling, together with statistical methods, data handling, reporting and resource requirements. The report does not address classification schemes or EQOs and EQSs; these will be the subjects of later reports. For the 1990 survey the previously-used means of assessing water quality and classification will be used, together with a concurrent programme designed to extend its scope and content.
