Title: Hiz, Oughton and Purwell environmental appraisal. Vol 1 appendices
Author: National Rivers Authority Anglian Region
Document Type: Monograph
The essential objectives of this environmental appraisal were to catalogue the present-day ecological, conservation and amenity value of the in-river, riparian and associated wetland systems of the River Hiz, Oughton and Purwell, from their respective sources downstream to Cadwell Bridge, just north of Hitchin. These objectives were achieved through the combined processes of historical data review, consultation with interested bodies and considerable original baseline field survey work. This final report details the results of a 6-month study undertaken during April-September 1993, during which river corridor surveys and river landscape assessments were completed in accordance with standard NRA methodology, supplemented throughout with in-stream community and channel morphology surveys.
