Last October, silt traps were installed on the Salle Estate, which covers 2000 hectares in the Broadland Rivers catchment. These traps were designed to protect the Wensum, which is impacted by farm pollution.
The site sits within the University of East Anglia Demonstration Test Catchment area. As part of this project, drones have collected data from the silt traps and produced an impressive 3D model. This data will help sediment accumulation to be calculated. The idea is that more data will be collected in the coming months and years to enable the traps to be better monitored.
