Published on 30 Nov 2016 Text: During NRW's flood maintenance work on the River Rhymney, special silt wattles and silt mats were used to slow down the flow of the river and to capture sediment dislodged by the work. Working with company Frog Environmental, an innovative ‘bubble curtain’ was also trialled for the first time in a river in the UK. This curtain of air bubbles stretches across the river and helps to manage silt, as well as providing an acoustic barrier to absorb sound and increasing oxygen levels in the river - protecting fish and other river life during the disturbance. |
