Coastal Mining and its Influence on Coastline Stability

coastal mining on the coastal sand system, as an anthropo-genic driving force, is assessed as a proxy of the state of the coast in this context. Note that the biotic, economic and societal components of the coupled coastal system are described in other sections of this book. The types of coastal mining activities in the WIO

Coastal development linked to human settlements, industry, aquaculture, and infrastructure can cause severe impacts on near shore ecosystems, particularly coral reefs. Coastal development impacts may be direct (e.g., land filling, dredging, coral and sand mining for construction) or indirect (e.g., increased runoff of sediment and pollutants).

Sand mining Wikipedia

Sand mining is the extraction of sand, mainly through an open pit (or sand pit) but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete.It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface.

What is dredging?

Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies. It is a routine necessity in waterways around the world because sedimentation—the natural process of sand and silt washing downstream—gradually fills channels and harbors.

This process utilizes magnetic and float separation to remove impurities. After the sand has been washed and dried and contaminants have been removed, it is screened. In this process, sand is separated according to grain size and stockpiled for future blending. These numerous demands for sand require mining of our dunes and other sand resources.
