ABSTRACT
This chapter covers the possible effects of sea level rise (SLR) on river dominated parts of the Niger delta. It aims to study the interaction between the strong hydraulic currents flowing from the upstream fresh water zone and the flooding in the coastal zone with future SLR with river floods occurring more frequently than before. The chapter simulates the effects of coastal flooding on the wave dominated parts of the Niger delta under SLR conditions. For most coastal areas the possibility of coastal flooding in a year are quite high. High sea levels can cause inundation of coastal areas; e.g. parts of the Mississippi delta and Black River marshes in the US have already been submerged by rising sea levels. Inundation due to SLR will have a great effect if areas under fresh water regimes are turned into salt water swamps or wetlands.
