Flooding:
Many islands in the Delta are below sea level, relying on levees for protection against flooding and tidal inundation. Most of them are farmland
There are many factors contributing to relative sea level rise (RSLR), Westerly Winds, Spring Tides, land subsidence due to compaction of organic soils (Peat), drainage from irrigation, .
Today, the Delta is largely devoted to agriculture, and includes about
55 islands or tracts that are imperfectly protected from flooding by
over 1,000 miles of levees.
