Abstract

A granulometric characterization of the sediment was performed in the Farfán estuary, located in the Gulf of Montijo. At six sainfoins, over six months, sediment samples were triplicated at depths of 5 and 10 cm, using 2" diameter PVC nucleators. Once in the laboratory the samples were dried in an oven. The material was selected through the dry screening technique (100 g of sample), using the USSM mesh No. 10, 18, 35, 60, 120, 230 and bottom in a Ro-Tap equipment with Tyler column. Individually, the sediment was formed by sand, with the corresponding components: very coarse sand, coarse sand, medium sand, fine sand and very fine sand, well represented, plus silt plus clay. The sediment did not show horizontal (between seasons) or vertical (between surface and bottom) variations; it originates in a river environment, is transported by rolling and leaping near the bottom and is deposited in a characteristic riverine environment, with influence of coastal marine of some energy level. It should also be noted that the composition of the substrate is important in the distribution of littoral benthic organisms.
