Establishing a comprehensive dataset for the rivers we are working on is the first stage of any project. It allows TRT staff to identify the issues affecting rivers, the current status of the river and the other projects and initiatives which are already underway in any part of the catchment.
The first stage of any investigation is the desk study and TRT has developed map-based applications such as the Dove Catchment Mapping Portal to bring together a number of datasets for a particular river.
TRT has also produced webmaps for the Dove, Soar and Lower Trent and Erewash.
The use of modelling software enables TRT staff to identify potential issues in a particular part of a catchment. For example, we use SCIMAP as a tool for modelling and mapping diffuse pollution risk across landscapes. The models produced can be used to guide walkover surveys and more in-depth investigation.
The Trent Rivers Trust involves volunteers in the survey and characterisation of rivers whenever we can. Not only does this help us to compile information, but it also enables more people to learn about their local river and then look after it. Here are some of the techniques we use ourselves and with our volunteers:
Modular River Physical Survey (MoRPH)
is a new way for river enthusiasts to record and assess physical habitat and hydromorphological functioning in their local rivers and streams. We use it directly and train and support others to do so and we use the MORPH website to gather information about rivers we have surveyed.
We train volunteers to survey their local brook to record and assess all outfalls in order to identify sources of pollution.

We use this website to record obstacles and it can be a useful resource to find out more about obstacles on any river.
