The works will be guided by regular monitoring of the river channels to determine the requirements for each maintenance dredge. The strategy includes some new dredging and a programme of maintenance dredging. There was a need to develop dredging designs which balanced the hydraulic benefit (in terms of reduction in flood levels) with the amount of maintenance dredging that will be needed in the future. Particular challenges on these tidal rivers include the high tidal range and the very high sediment loads from the Severn estuary. The presentation will cover the River Parrett and the River Tone. The first stage of the strategy covered the tidal reaches of the River Parrett and the River Tone, and the River Brue. ![]() In order to inform the dredging programme, a dredging strategy was prepared to identify the possibilities of dredging for flood risk reduction. The plan includes a programme of dredging to reduce flood risk. ![]() The Somerset Rivers Authority developed a flood action plan for the Somerset Levels and Moors that covered all aspects of flood management including engineering works and non-structural measures. In: Flood & Coast 2017, 28-30 March 2017, Telford, UK.įull text not available from this repository.įollowing the severe floods of winter 2013/14, an emergency programme of dredging was carried out on the tidal reaches of the River Parrett and the River Tone to reduce flood risk to the moors and the communities that were affected by the flooding. A dredging strategy for flood management on the River Parrett and the River Tone in Somerset.
