Civil Engineering Government Rehabilitation of the Beach Sand Ecosystem
Erosion as Serious Threat
Once just a minor nuisance, years of beach erosion had begun to seriously threaten nearby buildings and businesses as well as the beach of Saint-Jean itself. Simple re-sanding operations had already failed in earlier efforts.
Strategy of Rehabilitation
A new strategy of rehabilitation for the beach was begun with a first step of recapturing sand currently drifting out to sea on the bottom of the bay of Saint-Jean and using a boat to pump it back to the beach. Normally, the ecosystem is a cycle of sand shifting back-and-forth with the wind & waves between sea and beach in a natural balance.
Multi-Step Ecosystem Rebalance
Unfortunately, loss of seagrass combined with a dying barrier reef strained the ecosystem and led to the drastic erosion. In addition to the sand excavation efforts, steps to re-grow the coral of the barrier reef and restore seagrass are underway. Collectively, the timely intervention of these actions rebalance a natural cycle that had simply fallen out of sync.
