  abstract = {{T}he {V}olta {R}iver delta developed as an asymmetric lobe in a tectonic offset on the coast of {G}hana. {T}he delta comprises a large curvilinear spit that widens in its central portion due to the adjunction of successive sandy beach ridges. {T}he appearance of a distinct spit, in lieu of a continuous barrier from the present mouth of the {V}olta {R}iver to the {B}ight of {B}enin coast, may be an outgrowth of a natural change in the location of the mouth of the {V}olta. {T}he spit marks a segmentation of the unique sand drift cell that hitherto prevailed on this bight coast. {S}pit growth has been accompanied by a wave of erosion over the last century of the immediate downdrift sector of the bight coast, endangering the town of {K}eta. {E}rosion since the 1960s may have been aggravated by the construction of the {A}kosombo hydropower dam. {T}he tip of the spit has recently welded to the shoreline, thus assuring resumption of sand supply from the {V}olta towards the rest of this formerly sand-starved sector of the bight coast. {B}locking of sediment by the {A}kosombo {D}am is, in due course, likely to become the overarching factor in delta shoreline stability.},
