It has to do with something called ‘beach feeding’
The Municipality of Vellinge, located on the southwestern tip of Sweden, is a picturesque and popular beach and retreat destination for many Swedes, having been declared the second-best place to live in that country in 2009. It, however, also has an ongoing problem with coastal erosion.
Recent storms had hit and damaged the beaches of the municipality. In order to restore the capacity of the beaches, the Municipality has a permit to lay a maximum of 20,000 m3 of sand per year. This technique is called ‘beach feeding’.
Apparently, nature has a way of healing itself, as long as there is steady weather and predictable patterns. Sand that has been washed away in the winter can be washed back by the sea by summertime. However, increased climate volatility also threatens the healing process of the beaches.
The shoreline along the coast is both dynamic and affected by a sea-level rise. For that reason, Vellinge municipality has investigated how the shoreline will change over time. The municipality has estimated the need for sand in a 100-year perspective to better understand the processes and to be able to take the necessary measures and come up with cost estimates. Talk about having a long-term vision.
The study shows that the cost of preserving the position of the shoreline with the help of shore feeding increases over time, as the average water surface rises. So, in order to maintain the bathing cabins on the beach in their current location, approximately 2,000,000 m3 of sand will be needed by the year 2100.
“Vellinge Municipality works with what we call soft and nature-based protection. Sandy beach and its immediate environment, such as water edges and dunes, are a dynamic environment and to maintain the sandy beach, the dynamics also need to remain, which means that harsh protection could affect the sand movement and most likely create problems in another place,” explained Lisa Sundgren, a gardening expert, quoted by the Vellinge municipal website.
As for the beach bathing cabins, the municipality sees a problem in the long-term perspective and investigates alternative locations together with the County Administrative Board.
