The paper sets out UKTAG’s guidance on the framework for the identification of, and assessments of ‘type-specific’ risk thresholds for deciding if a water body is likely to fail to achieve the ‘good status’ objectives in relation to existing biological classification schemes and monitoring data
The paper sets out UKTAG’s guidance on the framework for the identification of, and assessments of risks from, abstraction and flow regulation pressures on river, lake, transitional and coastal water bodies as required by Article 5 of the Directive.
This paper describes the development of a typology for England, Wales and Scotland. It does not describe the rivers typology development for Northern Ireland, which is being undertaken by the North/South TAG for Ecoregion 17.
