Resumo: The present paper is a contribution to the study of the Upper Grande River, Nova Friburgo. It is a preliminary study of the relationship between the river-bed sediments and the declivity of the river profile. Granulometric analysis were performed on channel sediments in attempt to find a sedimentological caracterization of the river. The following parameters were computed: central tendency (median grain size (Md;) and mean grain size (M Z) , dispersion (σI) , assimetry (SK I) and curtosis (K G).The data analysed shows two distinct environments: that of the headwaters and that of the base level. Both environments are composed of poorly selected sediments.
