The stream, Nant Trawsnant, drains into the Llyn Brianne reservoir, Powys, United Kingdom. The data are for a 31 year period covering 1st April 1982 to 1st April 2012. The streamflow and acidity data are derived from 15 minute resolution observations throughout the calendar year 2013 from associated stream gauging and water quality stations on the Nant Trawsnant. The monthly rainfall measures presented, were derived from local rain gauges. The monthly temperature measures presented were derived from observations at a weather station near Talgarth, Powys. Routines within the Lancaster University Computer-Aided Program for Time-series Analysis and Identification of Noisy Systems (CAPTAIN) Toolbox for Matlab were used to develop a dynamic model of these data. These models were then used to simulate the 31-year record for which monthly statistics were derived. The statistics were derived to develop greater understanding of the controls on the long-term dynamics of aquatic biodiversity observed by other researchers in this stream. The work was part of the Diversity in Upland River Ecosystem Service Sustainability (DURESS) project, NERC grant NE/J014826/1. Members of staff from the Lancaster Environment Centre, Lancaster University installed, maintained and downloaded the stream gauging and water quality stations and also carried out statistical analysis of the data.\n","distributionFormats":[{"name":"Comma-separated values (CSV)","type":"text/csv","version":"unknown"}],"distributorContacts":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"distributor","email":"info@eidc.ac.uk"}],"funding":[{"funderName":"Natural Environment Research Council","funderIdentifier":"https://ror.org/02b5d8509","awardNumber":"NE/J014826/1","awardURI":"https://gtr.ukri.org/projects?ref=NE/J014826/1","orcid":false,"ror":true}],"id":"b085a784-0e16-4174-b208-465a8f43c8c8","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/b085a784-0e16-4174-b208-465a8f43c8c8.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"inspireThemes":[{"theme":"Hydrography","uri":"http://inspire.ec.europa.eu/theme/hy"},{"theme":"Environmental Monitoring Facilities","uri":"http://inspire.ec.europa.eu/theme/ef"}],"keywordsOther":[{"value":"Conifer plantation"},{"value":"Matlab"},{"value":"Streamflow"},{"value":"Rainfall"},{"value":"pH"},{"value":"CAPTAIN toolbox"}],"keywordsPlace":[{"value":"Powys"},{"value":"Nant Trawsnant"},{"value":"Llyn Brianne"}],"keywordsProject":[{"value":"Diversity in Upland River Ecosystem Service Sustainability (DURESS) "},{"value":"Biodiversity & Ecosystem Service Sustainability (BESS)"}],"licences":[{"value":"This resource is made available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}],"lineage":"The streamflow and acidity data are derived from 15 minute resolution observations recorded onto Campbell Scientific CR1000 data loggers throughout the calendar year 2013 from associated stream gauging and water quality stations on the Nant Trawsnant.
