River Surveillance Network Analysis Ready Data (NCEA)
The River Surveillance Network (RSN) is a statistically designed national monitoring network consisting of an unbiased and representative set of monitoring sites across English rivers. It will give a clear picture of river health across England by monitoring a wide range of parameters, supporting long-term measurement and detection of change. RSN monitoring follows a five-year panel design that balances temporal and spatial coverage. Across the five-year cycle, 1,600 unique sites will be monitor
