Scotland River Temperature Monitoring Network (SRTMN) - Predictions of river temperature and sensitivity to climate change

11311655Scotland River Temperature Monitoring Network (SRTMN) - Predictions of river temperature and sensitivity to climate changeEdited by MartynC.100015086layer_information_pageund1508248013154531085100154531085155River temperature is an important control on the health of fish populations. Under climate change it is expected that river temperature will rise with potential consequences for fish populations. Therefore, rivers and fisheries managers require information regarding 1) where the maximum river temperatures occur (where is hottest) and 2) where is most sensitive to climate change (where may change the most). This information can then be used to decide where to plant trees. The layers presented here provide this information for Scotland. River lines in the layers were derived from a Digital Rivers Network licensed from the Centre for Ecology and Hydrology (CEH). The details of modelling work that produced these layers can be found in the associated peer reviewed manuscript: Jackson et al (2018) ‘A spatio-temporal statistical model of maximum daily river temperatures to inform the management of Scotland's Atlantic salmon rivers under climate change.’ (see link under ‘Additional Information’ Tab). The outputs of this work are illustrated as four layers on Marine Scotland Maps NMPi: <ol> <li>SRTMN – Predictions of maximum daily river temperatures for the hottest day between July 2015 and June 2016.</li> <li>SRTMN – Predictions of maximum daily river temperatures for the hottest year in the last 20 years (2003).</li> <li>SRTMN – Predictions of the change in river temperature that would result from a 1°C increase in air temperature.</li> <li>SRTMN - Management priority on a scale of 1:9 where 1 is highest priority (i.e. high river temperature and high climate sensitivity) and 9 is lowest.</li> </ol>   filtered_htmlRiver temperature is an important control on the health of fish populations.

SRTMN is a strategically designed and quality controlled network being delivered by Marine Scotland Science – Freshwater Fisheries Laboratory (MSS-FFL) in collaboration with local rivers and fisheries trusts and boards. Details on SRTMN and the network design can be found in Jackson et al (2016) ‘A novel approach for designing large-scale river temperature monitoring networks’. (see link under ‘Additional Information’ Tab). The daily maximum river temperature model for Scotland allows current and future river temperatures and sensitivity to climate change to be predicted from; the day of the year (DoY), air temperature on that day, location in the country (region/hydrometric area), location on the river network and the characteristics of the river (elevation, bankside woodland and channel orientation). The predictions can be used to identify areas which may benefit from management action such as native tree planting to reduce maximum temperatures. This information should be combined with an understanding of the processes controlling the effectiveness of riparian shading to make decisions on the precise locations for planting (see Marine Scotland Topic Sheet ‘Where should we plant trees’ under ‘Additional Information’ Tab). The single layer 4 has been developed by (1) dividing the predictions of layer 2 and layer 3 into 5 equal categories between the minimum and maximum observed values (2) assigning these categories a value ranging from 1 (the hottest / most sensitive rivers) to 5 (the coolest / least sensitive rivers) (3) sum the rankings (-1) to produce an overall priority ranking (1:9) where rivers ranked as 1 are the highest priority for management (i.e. high river temperature and high climate sensitivity) and 9 the lowest. The details of the model and predictions can be found in: Jackson, F.L., Fryer, R.J., Hannah, D.M., Millar, C.P., and Malcolm, I.A.
