The protection measures comprised two phases: the construction of gabions and beach nourishment - the only scheme of its kind in Scotland. Around 18,500 cubic metres (? tonnes) of sand were deposited along a 300 metre stretch of dunes in between the estuary and the 8th hole of the Jubilee Course, to build up the eroded dunes. This new raised area was planted with marram grass to improve stabilisation. Over two thirds of the sand in still in place despite two winters with storms and gale force winds.
"I am very impressed that it has stood up so well despite major storms. Most of the sand that has been lost was blown backwards, replenishing existing dunes," said George Lees from Scottish Natural Heritage. "Every recharge scheme is different depending on local circumstances, but they can not be expected to last indefinitely. This is certainly holding up well and we will continue to follow the monitoring with interest."
Further along the estuary 100 metres of hard engineering, in the form of sloping gabions, was put in place to protect the dunes bordering the 8th tee of the Jubilee Course. Here the sand used to cover the gabions has been largely washed away.
"These coastal defences were the result of extensive consultation with environmental organisations. They represent a major investment by the Trust with no guarantee of success, so naturally we are pleased that they are working well so far creating a vital buffer zone between the estuary and the Links," said Alan McGregor, general manager, St Andrews Links Trust.
