C-NFM
Cumbrian NFM effectiveness monitoring network
1st Feb 2019 to 30th Apr 2026
This project is being delivered as part of the national DEFRA Flood Defence Grant in Aid (FDGiA) Catchment Scale programme aimed at delivering innovative Natural Flood Managment (NFM) monitoring on Catchments in Cumbria linked to the rest of the NFM programme. Natural Flood Managment is defined as anything that is or mimics 'Working with Natural Processes' (WwNP). In FCRM this means using NFM techniques to reduce flood risk and deliver multiple benefits.
The project comprises of four phases:
- Phase 1 involves purchase of five additional flumes to those installed by the NERC Q-NFM project; purchase of mobile network of stand-alone water-level recorders for use in NFM features near FRPB flumes; and the purchase of Turner fluorimetry system to quantify effective storage from leaky dams or channel realignment, and check flume calibration. The flume installations purchased by this project are associated with the five communiities: (1) Windermere road, Grange-over-Sands (Eggerslack stream), (2) Flimby village (Pennygill), (3) Sedbergh north of Station Road (as stream draining Winder), (4) Old Tebay (Tebay Gill), and (5) Mallerstang (Fallsike Gill).
- Phase 2 involves installation & monitoring of the equipment purchased, together with analysis of NFM-related change in rainfall-streamflow response with respect of local NFM features. Additionally, public sharing of live rainfall and streamflow data.
- Phase 3 involves renewal of the telemetry licence and refurbishment of the flumes.
- Phase 4 Lastly, phase 4 involves continued monitoring, analysis and data sharing from May 2021 to April 2026.
