The present study aims at analysing the dimensional distribution of granulate grains all along the Togolese littoral and identifying the law of their longitudinal distributions. In this regard two hundred and ten (210) samples are collected all along the Togolese littoral from the Togo-Ghana border up to Togo-Benin border and another ten (10) samples on each side of a spike located at 37.5 PK. Samples dried at 105°C for 20 h are then subjected to screening test. Their longitudinal size distributions, uniformity coefficients and bendings are then specified. It is apparent that the sediments of the Togolese littoral consist of grains of category ‘’F3’’ that are getting bigger and bigger, less and less tight, badly graduated and more open in accretion and erosion zones in the direction of the littoral drift. Natural and artificial works all along the Togolese littoral enable to identify three categories of sediment (fine, medium-size and big) corresponding to properly determined usages in the concrete.
