BHA Sedimentation Committee

The former Blakeney Channel Coastal Community Team (B3CT) joined forces with the Blakeney Harbour Association to form the BHA Sedimentation Committee. The former members of the B3CT and others will now continue working towards our shared objectives as part of this newly formed committee. This step was jointly considered to be a great opportunity to consolidate our efforts, experience and resources to ensure we expedite our common aims and objectives.

The work performed by the BHA Sedimentation Committee ensures that the Blakeney waterways remain navigable for current and future vessel usage. Our work is related to the measurement and management of sedimentation and channel/bank movements and assists in maintaining the community, economy and heritage of Blakeney and surrounding villages.

This presentation shown above describes an analysis of the output from two drone surveys of the Blakeney waterways. The Bathymetric surveys, completed in 2017 and 2023, are water-based drone surveys that map the depth and shape of underwater terrain to illustrate and measure the land that lies below. 

Page 2 of the PDF provides the reader with background and context for understanding this detailed comparative analysis between the 2 surveys.

Our intention is to perform another survey in 2026 and to increase the scope to include a large area of Blakeney Harbour. This could include additional areas of the surrounding waterways e.g. Morston, Cley etc. This additional comparative to the previous 2 surveys will provide further evidence and insights into the direction the sedimentation and channel bank movement is taking.
