Defending a coast without passing the problem on W1-mt_3Px4N4va3o-s1

  1. Moving life inland on purpose, phased · Retreat is planned and funded, which is what separates it from simply losing.
  2. Sea wall and beach nourishment · Walls are hard, nourishment is soft. The mixed pair names one of each.
  3. True · Trapping sand here means less sand arriving there. That is the trade.
  4. When defences cost more than they protect · Retreat beats rescue when the bill passes the value guarded.
  5. Cost, lifespan and downstream effect · Money, years and neighbours: those three lines keep the comparison honest.
  6. False · Every scheme picks winners and losers. Engineering never decides alone.
  7. Homeowners, councils and neighbours along the shore · Savers, payers and next door beaches all hold a stake in the choice.
  8. The wall moved the problem along the shore · Sand trapped here is sand stolen there. Problems travel along coasts.
