Groyne #26

 
 

The images show some of the work being carried out on the beaches of Poole Bay, Dorset. Specifically, the replacement of the wooden groynes that are designed to prevent longshore drift. Speaking to one hard-hatted chap surveying the scene, he mentioned that all things being equal it will take a month to replace each one. This involves drilling holes for the numerous posts, which range between 10 and 13 metres in length, digging out the sand once all are sunk to the required depth, and then adding the boards to complete each 45 metre structure.

From what I can see they are working on only two timber groynes at a time, and this is restricted to the winter months; the beaches being needed for tourism during the summer. So, bearing in mind that the bay has 13km (8 miles) of beach, and each wooden groyne is spaced 120 metres apart, by my reckoning there are... er, loads to do.
