Impacts of infrastructures
  • Stabilize beach
  • Build-up sand
  • Create dredging problems
  • Create rip tides and dangerous currents
  • Cause more to be spent on renourishment
  • Leads to indirect problems ( sand
    harvestingdestruction of marine habitats, etc.)
  • Cause us to believe coastal areas are safe for
    development (only temporary)
