Geomorphic assessments

Geomorphic assessments utilises an understanding of the fluvial processes and morphology of a reach to predict the impact of such activities as bank protection, overgrazing by sheep and cattle, weir removal and changes to flow and sediment input. (click here to see example)

 

River Habitat Surveys (RHS) and Lake Habitat Surveys (LHS)

We are able to undertake standard assessments for physical habitat quality of rivers and streams (River Habitat Survey) and lakes, ponds and reservoirs (Lake Habitat Suvey) using accredited staff. (click here to see example)

 

MImAS assessments

Morphological Impact Assessment System (MImAS) is a tool developed by SEPA in conjunction with CRESS to provide a basic assessment of the activity footprint of a range of river engineering activities in relation to its impact on river ecological status. It is based on assigning an individual river to a geomorphic type and the assumption that each river type has the capacity to absorb a given level of a range of engineering activities. Since CRESS was involved from a very earlier stage in developing MImAS and in testing its validity, we are highly qualified to survey rivers and apply this useful tool under a range of scenarios.

Development of assessment tools

CRESS has been involved with Environmental protection agencies and organisations such SEPA and SNIFFER in the development of a range of tools associated with the Water Framework Directive (WFD); for example the MImAS tool and the Canal classification tool. (click here to see example)

 

Fish surveys

CRESS can provide assessments of species composition, abundance, habitats and pressures on freshwater fish and fisheries resources. (click here to see example)

 

Aquatic plants and macroinvertebrate surveys

Assessment of species composition, abundance and richness of aquatic plants and macroinvertebrates are important for assessing the nature conservation value of a reach and can be used as indicators of ecosystem health.

 

Water quality analysis

We have laboratories and equipment that can measure a range of water quality parameters including suspended solids, pH, dissolved oxygen, dissolved carbon, phosphate, nitrate and a number of other anions and cations. (click here to see example)

 

Hydrological monitoring

CRESS has the capability to design, install and monitor surface and groundwater and understand the hydrology network and water budgets in a water system. (click here to see example)

 

Spatial and Statistical analysis of river data sets

We are able to analyse datasets that may be in the possession of organisation for trends in the data or statistical differences between rivers and reaches or before and after treatments/activities.

 

Fluvial Audits

The Fluvial Audit (FA) uses contemporary field survey, historical map and documentary information and scientific literature resources to gain a comprehensive understanding of the river system and its catchment. FA is part of a sequence of survey types that we can offer to address specific issues. (click here to see example)

 

Advice on ecological aspects of SUDS

Sustainable Drainage Systems (SUDS) are considered a sustainable alternative to traditional drainage schemes. CRESS can provide recommendations concerning aquatic plant communities that are able survive under a given water quality and have the ability to uptake nutrients.
