There are two main factors contributing to the shrinking of the Mississippi River Delta.

1) Dams and Reservoirs along the Mississippi River trap between 70 - 90 % of the sediment that passes through them. This means that the suspended dirt that makes up the Delta is no longer being replaced as the ocean washes it away.

2) This process is being accelerated by rising ocean temperatures causing more extreme weather events that pull sediment out into the ocean with them (like Hurricane Katrina)
