Meanwhile a further tributary catchment subject to riparian planting and fencing showed no significant change in lag times.<\/p>\n\n\n\n<p>The Eddleston Water Project is a 10-year long, whole catchment project to demonstrate the effectiveness of NFM in the real world &#8211; underpinned with empirical evidence.  Publication of these results is a key milestone in the project.  The combination of record lengths and gauging density makes Eddleston one of the UK&#8217;s premier sites for the study of NFM in terms of surface water hydrological change, as well as many other related aspects, including groundwater, channel morphology, ecology and ecosystem services.  Our monitoring and analysis are ongoing, with support from the Scottish Government, Tweed Forum, Scottish Environment Protection Agency, Scottish Borders Council, British Geological Survey, Forest Research, Forestry &amp; Land Scotland and research partners.
