The Engineering Behind the Defence

Rock Armour Groyne

Massive igneous boulders strategically placed to dissipate wave energy before it impacts the main sea wall.

  • High durability granite
  • Low maintenance

Stepped Revetments

Reinforced concrete steps that break wave power while providing integrated public seating and beach access.

  • Wave energy dissipation
  • Enhanced accessibility

Beach Nourishment

The replenishment of thousands of tonnes of local sand to maintain a natural profile and buffer for the town.

  • Ecological synergy
  • Storm surge buffering

A Changing Climate: The Risks We Face

As global temperatures rise, Barmouth faces unprecedented challenges. Our hub monitors these variables to ensure the defence scheme remains effective for decades.

Sea Level Rise

Projected 0.5m - 1.0m rise within 50 years, increasing flooding frequency.

Storm Intensity

More frequent and aggressive "Super Storms" threatening the railway link.

Biodiversity Preservation

Careful management to protect the Mawddach Estuary's unique SSSI status.

Balancing Protection & Tourism

Understanding the impact of major engineering on our resort's identity.

Benefits for Visitors

  • New wide-access promenade paths for families and wheelchair users.
  • Integrated seating and "viewing steps" creating social spaces.
  • Guaranteed beach preservation for generations to come.

Implementation Trade-offs

  • Temporary disruption and restricted beach access during key works.
  • Visual shift from natural dunes to engineered rock armour.
  • Increased heavy vehicle traffic through town during construction phases.

The Path to Completion

Phase 01

Preparation & Surveys

Site logistics, ecological assessments, and local public consultations.

Phase 02

The Heavy Lifting

Importing 20,000+ tonnes of rock and installing the stepped revetments.

Phase 03

Final Flourish

Landscaping, lighting, and reopening of the improved promenade.
