Field-based method designed for consistent application by non-experts, to assess physical structure of stream, primarily for ecological and riverine-habitat purposes. The ability of RHS to inform or replace assessment methods used in other European countries has been investigated (Erba, et al. 2006; Raven, et al. 2002). The RHS conforms to the river classification and assessment requirements set forth by the European Water Framework Directive.
- Determine catchment characteristics
- identify attributes of high quality ‘benchmark’ streams
- identifying species-habitat relationships
- provide input to environmental impact assessments
Includes input data of: Valley Form, Fluvial Features (riffles, pools, point bars), Artificial Features, Bank and Channel Material Bank and Channel Modification
Bank and Channel Features, Flow Type, Adjacent Land Use, Adjacent Land Cover – detailed, Channel Vegetation, Bank Profile, Channel Dimensions:
(Banktop height, Bankfull height, Water Depth, Channel width, Bankfull width), Vegetation choking of channel, Special Features, Overall Characteristics
- Habitat Quality Score
- Modification Score
- Habitat Quality Assessment Scheme
