Abstract
• Three sites in the Stroud Frome and Twyver catchments in Gloucestershire, UK were monitored for hydrology, sediment and water quality variables in five different flow conditions; these included two featuring leaky barriers installed in different years and a natural control site. • The results indicated that that leaky barriers were effective at reducing channel velocity and storing water up to a 1 in 9-year flow event (no higher magnitude flow events were captured), but did not impact on low flow velocities. • The time a leaky barrier had been in place was important; there were improvements in water quality and a reduction in the suspended sediment content when leaky barriers were present and these were more pronounced the longer a leaky barrier had been present. However, associated with this there was an increase in silt content in the bedload sediment upstream of leaky barriers which was increased through time since installation.
