    Sedimentation from rivers is called fluvial sediment. Sediment itself refers to matter that settles at the bottom of a body of water or a liquid environment. This could be pieces of eroding rock, sand, clay, pebbles, etc.

    Sand technically is a specific grain size of clasic (broken) material, from a fraction of a millimeter up to two mm in size. Smaller particles are silt, clay, or mud, and larger ones are pebbles, cobbles, and boulders – with variations in terminology depending on which system you use. River sediment could include all of these, which are size terms and do not relate to the composition.
