Résumé: Previous studies by various agencies have shown that widespread erosion is occurring on the Nigerian shoreline and in some places, the rate of shoreline retreat is so rapid as to be alarming. Shoreline stabilisation methods adopted for combating erosion along our coasts have been counter-productive and, in many cases, aggravated the problem largely because such solutions had been, and are being, carried out without consideration or understanding of fundamental principles of shoreline dynamics and processes. Following a review of case histories, the Nigerian Institute for Oceanography and Marine Research initiated in September, 1981 a data acquisition programme aimed at making a scientific input into long term and large scale coastal management planing in Nigeria. This paper details the preliminary results and interpretations from on-going beach profiling and littoral environment observations at four selected erosion monitoring stations at Victoria Island, Forcados, Brass and Ibeno-Eket Beaches spanning the entire Nigerian coastline. State-of-the-art knowledge of coastal stabilisation and beach nourishment techniques are evaluated in the light of data presented in this work. Projected research efforts of the Institute along the Nigerian coastline are outlined and future national policy options suggested
