Chyandour




Tidal changes at Chyandour. Here you can see the tidal range where the beach is totally submerged at high tide. There is a large area of the beach uncovered at low tide due to the low gradient of the beach. In rough weather waves can spread high up the rock armour, to the left of the image, it is also clear here where seaweed has covered the rock armour.
New studies are currently being carried out looking into rock armour and adapting it to encourage more wildlife to grow there, by using sand bags and gavel between the spaces of rocks it is hoped that it will encourage sedimentation creating habitats amongst the rock, increasing the biodiversity.






Here at Chyandour looking through one of the three tunnels at high and low tide it is possible to see the rocks which in spring tides or rougher conditions are impossible to see. These rocky formations house a variety of marine species with mussels being the most common species.
