ABSTRACT:
An aquatic sediment and current monitor adapted to be positioned in a body of water comprising an elongate, vertically alignable, collecting tube having an open upper end and a closed lower end for collecting, over a long period of time, the natural materials and polluting substances that accumulate in the body of water. A generally funnel-shaped magnifying cone is positioned with the small diameter end thereof extending into the open end of the collecting tube to magnify the amount of sediment and pollution collected. A baffle is positioned in the magnifying cone adjacent the large diameter end thereof. A marking material dispenser is provided for automatically marking, at regular intervals, the quantity of sediment and pollution accumulated in the collecting tube during such intervals. A current wheel is positioned above the baffle for measuring the velocity of currents in the water body. A marking material dispenser is also provided for automatically marking the quantity of sediment accumulated in the collecting tube after a predetermined flow of current passed the monitor.
