AI Technical Summary

Technical Problem

Mangroves, crucial for coastal protection and biodiversity, are regressing due to climate change and human activities, and mangrove replanting programs face low survival rates due to inadequate methods and unfavorable hydro-sedimentary contexts, necessitating a solution for preventing or reducing coastal and river bank erosion.

Method used

An artificial reef system with elongated elements forming a porous barrier anchored to the water bottom, mimicking mangrove structures to dissipate wave energy, reduce sediment resuspension, and promote deposition, while being designed to withstand high swell environments and support local biodiversity.

Benefits of technology

The artificial reef system effectively prevents or reduces coastal and river bank erosion, stabilizes substrates, supports mangrove recolonization, and maintains ecological functionalities, enhancing carbon capture and storage, and promoting local biodiversity.

Abstract

The disclosure notably relates to an artificial reef for preventing or reducing coastal or river bank erosion. The artificial reef comprises means for anchoring the artificial reef to a water bottom. The artificial reef comprises elongated elements extending at least partially upward so as to form a porous barrier extending upward from the water bottom when the artificial reef is anchored to the water bottom. The porous barrier formed by the elongated elements presents a substantially constant density vertically. The artificial reef comprises horizontal structural elements maintaining the elongated elements. The artificial reef forms an improved solution for preventing or reducing coastal or river bank erosion.
