Conwy Catchment Stream Discharge and Temperature Data 2008-2011

Discharge and in-stream temperature data for the Nant y Brwyn peatland headwater stream in North Wales, collected from March 2008 to July 2011. The dataset was created by the Environmental Information Data Centre to support annual run-off estimates and fluvial carbon flux calculations for this catchment within Snowdonia National Park.

Use Cases

• Calculate annual run-off estimates for the Nant y Brwyn catchment using discharge data.
• Estimate fluvial carbon fluxes by analyzing the relationship between discharge and in-stream temperature.
• Model hydrological processes in a peatland headwater stream environment over a multi-year period.
• Identify periods of equipment failure or stream freezing by analyzing gaps in the discharge and temperature time series.

Strengths

• Provides over three years of continuous environmental monitoring data from March 2008 to July 2011.
• Focuses on a specific, ecologically significant location: the Nant y Brwyn stream on the Migneint blanket bog within Snowdonia National Park.
• Data is curated and hosted by the authoritative Environmental Information Data Centre with a persistent DOI.

Limitations

• Contains documented gaps in the data due to equipment failures, battery issues, or stream freezing events.
• Limited to a single stream catchment, reducing generalizability to other hydrological systems.
• Temporal coverage ends in 2011, which may limit analysis of recent trends or climate change impacts.
