This layer describes the Recovery Potential of a reach, which is a measure of river energy based on specific stream power (W/m2) (see lineage section to understand how SSP is calculated). Rivers with higher energy have a greater capacity to 'self-heal' and can be restored using passive restoration techniques. In contrast, lower energy rivers require more costly interventionist restoration approaches such as remeandering. Through understanding the energy regime of the river we can design restoration to minimize the work needed and maximize the length of river improved by working with and enhancing the natural processes of the river. The dataset was developed in conjunction with the 'Will the river do the work?'

This was derived from the Slope layer (calculated using the 5 m next map DEM) and discharge at QMED (CEH QMED flood dataset calculated for each 50 m point), the channel width derived from channel outline from the 2008 Ordinance Survey maps. As part of the STREAM project the baseline waterbody was separated into reaches with a homogeneous character (similar slopes and channel width). This reaches were used and Specific stream power was averaged for each homogeneous reach to convert the 50 m point data to vector lines of the waterbody. The CEH baseline network was used to map the location of the rivers. The stream power was then used to derive the recovery potential categories. 7235 km of waterbody was walked in Scotland and the reference river type recorded as part of the less than good surveys. Stream power ranges were extracted and mapped for each river type creating the resilient to change, high, moderate and low recovery potential categories.", "licenseInfo": "
