The River Parrett near Burrowbridge is currently undergoing extensive dredging operations aimed at improving its capacity to handle floodwaters. The Somerset Rivers Authority has confirmed that this initiative is now in full swing.
Innovative Dredging Techniques Employed
Water Injection Dredging: A Proven Method
Following a successful trial in 2023, a Water Injection Dredging (WID) vessel named Borr is being utilized for the operation. This cutting-edge technique targets sediment removal from the river’s central channel, enhancing its ability to convey water efficiently.
Excavator-Assisted Cleanup
An excavator mounted on a floating platform complements the WID vessel by clearing material from the river’s upper banks. These sediments are strategically placed in Borr’s path, enabling the outgoing tide to transport them to the sea.
Benefits of the River Parrett Dredging Project
Improved Floodwater Capacity
The dredging program significantly increases the River Parrett’s capacity to manage floodwaters, reducing the risk of flooding in surrounding areas.
Enhanced Cross-Sectional Area
By removing sediment from critical sections of the river, the project creates a better cross-sectional area, ensuring smoother water flow during peak conditions.
Conclusion
The River Parrett dredging initiative represents a proactive approach to flood management, leveraging innovative techniques to improve waterway functionality. With the use of Borr and the excavator, the Somerset Rivers Authority is effectively enhancing the river’s resilience against potential flooding challenges.
