This linear, steep-sided channel was in much need of enhancement and following conversations with various local landowners, a scheme was put together to improve the river's form and function.<br /> <br /> The lack of gradient through the site limits the effectiveness of restoration techniques aimed at increasing flow velocity. This is exacerbated by long-term maintenance that has seen the river routinely de-silted to a substantial depth, exceeding 1.5m in some places. Consequently the work that was undertaken aimed to increase habitat availability and diversity. Specifically, more shelter was created for fish and small in-stream organisms by constructing brushwood mattresses. Shallow berms were installed to soften the edge between the aquatic and terrestrial environment, providing an area of transitional plants to establish. In some locations a two-stage channel was formed using old spoil embankments, maintaining conveyance but increasing flow velocity at low flows.<br /> <br /> Over the course of two weeks in October 2014 and with a budget of under £15,000, approximately 1.5km of river channel was enhanced.<br /> }}<br /> {{Image gallery}}<br /> {{Case study image<br /> |File name=Berm feature bressingham.JPG<br /> |Caption=Looking downstream at a berm feature that was installed on the true left-hand bank of the River Waveney<br /> }}<br /> {{Case study image<br /> |File name=Drill.JPG<br /> |Caption=High-powered drills were necessary for us to screw some of the wooden features in place<br /> }}<br /> {{Case study image<br /> |File name=Drilling.jpg<br /> |Caption=Timber screws were used to connect the woody-debris to the vertical stakes.

This linear, steep-sided channel was in much need of enhancement and following conversations with various local landowners, a scheme was put together to improve the river's form and function.<br /> <br /> The lack of gradient through the site limits the effectiveness of restoration techniques aimed at increasing flow velocity. This is exacerbated by long-term maintenance that has seen the river routinely de-silted to a substantial depth, exceeding 1.5m in some places. Consequently the work that was undertaken aimed to increase habitat availability and diversity. Specifically, more shelter was created for fish and small in-stream organisms by constructing brushwood mattresses. Shallow berms were installed to soften the edge between the aquatic and terrestrial environment, providing an area of transitional plants to establish. In some locations a two-stage channel was formed using old spoil embankments, maintaining conveyance but increasing flow velocity at low flows.<br /> <br /> Over the course of two weeks in October 2014 and with a budget of under £15,000, approximately 1.5km of river channel was enhanced.<br /> }}<br /> {{Image gallery}}<br /> {{Image gallery end}}<br /> {{Toggle button}}<br /> {{Toggle content start}}<br /> {{Case study subcatchment}}<br /> {{Site}}<br /> {{Project background}}<br /> {{Motivations}}<br /> {{Measures}}<br /> {{Hydromorphological quality elements header}}<br /> {{End table}}<br /> {{Biological quality elements header}}<br /> {{End table}}<br /> {{Physico-chemical quality elements header}}<br /> {{End table}}<br /> {{Other responses header}}<br /> {{End table}}<br /> {{Monitoring documents}}<br /> {{Monitoring documents end}}<br /> {{Additional Documents}}<br /> {{Additional Documents end}}<br /> {{Additional links and references header}}<br /> {{Additional links and references footer}}<br /> {{Supplementary Information}}<br /> {{Toggle content end}}</div>
