The battle over the future of Barmouth's beach has ignited a heated debate, with residents and experts alike weighing in on the proposed sea defence scheme. The plan, which aims to protect the resort from the encroaching sea, has sparked significant opposition, with critics arguing that it threatens the very essence of Barmouth's charm and tourism appeal. At the heart of this controversy lies the proposed construction of a 1.2km-long rock armour revetment and a 1.55-metre-high secondary wall, which have been met with fierce resistance from both locals and a renowned geologist, Dr. Graham Hall.
Dr. Hall, a former geologist at Aberystwyth University, presents a compelling argument against the proposed scheme. He warns that the beach, already at risk due to its off-shore topography and ongoing sand loss, could be entirely lost if the plan proceeds. This loss, he asserts, would significantly diminish Barmouth's appeal as a tourist destination, as the beach is a cornerstone of its allure. The geologist's concerns extend beyond the beach itself, as he predicts that the rock armour revetment would severely restrict access to the beach, an essential attraction for visitors.
The proposed secondary wall, with its 1.2km-long recurve face, is described by Dr. Hall as a "featureless concrete canyon," detrimental to people's wellbeing. He argues that the wall would do little to prevent sand loss and could even exacerbate beach erosion, leading to increased wave damage to the sea wall and promenade. This, in turn, could result in the closure of the promenade road and the loss of buildings in north Barmouth.
Dr. Hall offers a compelling alternative, suggesting four defence strategies that could save the beach and mitigate flooding for at least the rest of the current century. These include near-shore boulder reefs, raising the primary sea wall, retaining the existing dwarf wall, and creating a storm water retention lake that could become a tourist attraction.
The retention lake idea, in particular, stands out as a novel and ingenious solution. By storing storm water on a large piece of unused land, the lake could provide valuable tourism opportunities, transforming a less-visited area into a vibrant hub. This concept is not entirely new, as similar water parks with inflatable slides and climbing frames have gained popularity in Britain's warmer summers, successfully developed on lakes in Cardiff and Conwy.
However, the council has its own concerns, rejecting the idea of beach recharging and groynes due to minimal longshore drift impacts. They argue that the rock revetment, when combined with other measures, will significantly reduce the risk to life on the promenade and in Barmouth. Physical modelling has demonstrated the effectiveness and stability of the rock armour, and the council assures that accessibility and safety have been prioritised with new steps and a walkway.
Despite the council's efforts to address concerns, the opposition remains strong. Dr. Hall urges the council to reconsider, warning that without intervention, the beach's protective effect will be lost, leading to further damage to the primary sea wall and costly repairs. The geologist's passion for preserving Barmouth's natural beauty is evident, and his alternatives offer a promising path forward.
As the planning and marine licensing consents are set to be submitted, the future of Barmouth's beach hangs in the balance. The debate rages on, with residents, experts, and the council all having a say. The outcome will shape the town's destiny, determining whether the beach's beauty and tourism appeal will endure or be forever lost to the encroaching sea.
