The Demonstration Test Catchments (DTC) project is a joint Defra, Environment Agency (EA) and Welsh Assembly Government initiative working in three river catchments – the Wensum in Norfolk plus the Eden (Cumbria) and Avon (Hampshire).

The overall objective of the project is to provide evidence to test the hypothesis that it is possible to cost effectively reduce the impact of agricultural diffuse water pollution on ecological function while maintaining food security through the implementation of multiple on-farm measures across whole river catchments using local expertise to solve local problems.

  • 23 April 2016: Wild About the Wensum Again! This popular event celebrated its 10th anniversary this year and our Wensum Alliance stand had a high number of visitors who were keen to try out the catchment model demonstrating run-off and infiltation, testing river water, tap water and rain water samples nitrate levels, hearing about the DTC work on cover crops and taking part in a 'true/false' game about how oilseed radish can help mitigate water pollution. The youngsters were interested and enthusiastic - catchment scientists in the making!

NUTCAT event

  • 26 Feb 2016: NUTCAT 2050 Meeting at Salle NUTCAT event The Wensum and Eden DTCs invited farmers from the Wensum/Blackwater catchment to join experts from the UK Met Office for a meeting to feedback results from the data collected by the Wensum DTC team and to discuss weather trends and understand how changing weather patterns may affect the way we live and farm in the Wensum. The meeting also introduced NUTCAT 2050 (estimating NUTrient transport in CATchments to 2050)– a new project that will examine the role of land use and climate in nutrient runoff and implications for future water quality. Dr. Pete Falloon (Met Office Hadley Centre) compared data from local climate records against observed trends across the country and presented information on projected future climate change and Dr. Mary Ockenden (Lancaster University) led an interesting discussion session examining recent experiences relating to changing weather and how farmers are responding through changes in farming practices.

  • 21 Jan 2016: Cover, catch or companion? What are they and how do you best manage them to gain the benefits? CSF event
    This Catchment Sensitive Farming (CSF) event hosted by Natural England at Salle village hall invited farmers, particularly those in the Wensum catchment, to exchange knowledge on the use of cover crops to aid soil fertility. Cover crop use is becoming increasingly popular and this workshop focussed on the pro's and con's of their use, with first hand practical on-farm experience provided by Poul Hoveson. The event was attended by a good number of local farmers as well as staff/researchers from Natural England, Wensum DTC, Anglian Water, Agrii, Frontier, NIAB and others.
