In addition to the previous answer, as sea-level rises as a result of global warming and the associated deglaciation; the sub-environments associate with a river system will backstep landward.
For example, the Mobile-Tensaw River which feeds into Mobile Bay forms a large delta at the head of the bay. As sea-level rises due to deglaciation, the delta will backstep across the current low-lying delta plain. The low-lying plain will then become flooded extending the size of Mobile Bay as the delta further retreats landward.

One of the less-publicized results of global warming is global drying: when the average temperature is higher, the air can hold more water, so there is less precipitation. This would lead to there being less rainfall and lower rivers.
Some computer models shown more extreme weather due to global warming, and this would mean a greater variation in the annual river heights, bad news for those who live in floodplains near rivers.

at a guess it will cause excessive rainfall which will lead to flooding and erosion.
