Sieving sediment

A person wearing a lab coat and rubber gloves holds clear plastic tube with water running into a cylindrical metal pan.

Detailed Description

Washing a sediment sample through two sieves with distilled water lets us measure the fractions of gravel (bigger than 2 millimeters or -1 phi) and sand (2 millimeters to 63 microns, -1 phi to 4 phi). Smaller sediment passes through the sieves into a standard 1-liter graduated cylinder.
