The MoRPh Rivers field survey was originally designed for use by citizen scientists and non-profit organizations. It now forms one component of a suite of tools developed for River Condition assessment within Natural England’s Biodiversity Metric 3.1.

While MoRPh Cit Sci training provides a valuable approach for volunteers and researchers to gather evidence and build understanding of changes in the physical habitats of rivers and streams via and a basic set of 14 MoRPh indicators, all CS data are open source are shared via the CaBA Data Hub.

Our MoRPh Pro training combines the user-friendly MoRPh field surveywith River Type survey to generate and help interpret a detailed set of 37 indicators securely saved in a private workspace, providing environmental professionals with the in-depth knowledge and software tools to enable the baseline assessment of River Condition together with scenario modelling for target condition, as needed for Biodiversity Net Gain reporting.

River Condition Assessment Tools

The figure below outlines the structure of the River Condition Assessment. The individual components are discussed below:

1. MoRPh Field Survey

A field survey identical to MoRPh Rivers that characterises the local physical structure of a river channel and its margins. The survey is typically conducted over a river length of 10 to 40m.

2. MoRPh5

A sequence of 5 adjacent MoRPh surveys quantifies over 30 indicators that contribute to a preliminary condition score for a river subreach.

3. River Type Survey

A desk-based reach-scale (5 to 10 km) study identifies the hydrogeomorphological river type. This translates the preliminary condition score for each MoRPh5 into a final condition score, which reflects what is achievable for that river type.
