Why the new plan for the Torrent de ses Planes needs more than concrete

Answer

Why do flood projects in Mallorca also need upstream retention areas?

Retention areas slow down peak flows before water reaches a narrow torrent or road crossing. In Mallorca, that matters because intense rain can send too much water and debris downstream at once. Holding some of that water upstream reduces pressure on the main channel and can make the whole system more resilient.
