ABSTRACT:
A partitioning sediment trap adapted to be positioned in a body of water comprising an elongate, vertically alignable transparent collecting tube having an open upper end and a closed lower end for collecting, over a longer period of time, natural materials, contaminants, and polluting substances that accumulate in the body of water. A generally funnel-shaped cone is positioned with the small diameter end thereof extending into the open end of the collecting tube to magnify the amount of material collected. Means are also provided for automatically and efficiently partitioning and isolating undisturbed material accumulated in the collecting tube at regular time intervals.
