Grain size, sorting, skewness, and kurtosis studies are of great importance in order to texturally characterize the sedimentary environments. These parameters are useful in order to characterize the dynamic beach environment, which is of potential interest for research on natural resources and to interpret analogous ancient sedimentary environments. The purpose of this paper is to investigate the characteristics and distribution of sediments along Kenitra coast (Morocco) for first time using size grain analysis. Grain size analysis aims to determine physical properties and textural parameters such as mean, sorting, skewness and kurtosis. Samplings were done at different locations on the beaches, which represent low tide line, high tide line, foot dune and dune areas. The observation from this study shows an abundance of the medium sand to fine sand which indicates the prevalence of comparatively moderate-to low-energy condition in the Kenitra area. Linear Discriminant function (LDA) analysis of the samples indicates an aeolian, shallow marine deposition environment and less influence of fluvial (7%) process. Analysis of sediments using Passega's C-M diagram (C = one percentile in microns and M = medium in microns) of the Kenitra coast suggests that sediment deposition is mainly by rolling and graded suspension.
