Water temperature in rivers
Water temperature is of fundamental significance of aquatic animals, particularly those that are cold-blooded including fish and invertebrates. The growth, development and activity of these animals is directly related to the environmental temperature. Therefore, current and future changes in river temperatures will have critical impacts on the health of stream ecosystems. However, some river reaches will be more vulnerable to changes in water temperature than others, which may be resilient to change and therefore provide an important refuge to animals whilst surrounding river reaches warm (or cool). 

With Prof. Wilby (Loughborough University) and Julia Toone (Environment Agency), we set up a network of temperature sensors along the River Dove and River Manifold in the Peak District, UK. At each monitoring site we log a measure of the maximum, mean and minimum air and water temperature, every 15-minutes. 20 sites now have a 3.5 year record. These data time-series are made freely available at the following website: www.luten.org.uk

The data has been used to develop simple metrics that can be used to assess the vulnerability of river reaches to warming. In addition, the data was used to explore the potential lengths of tree shade necessary to prevent 1 °C rises in temperature. For more information, please see: www.luten.org.uk
