Abstract
This invention relates to a device and method for measuring the depth of water and sediment deposition in pipes, channels, overland flows and tidal beaches. Sediment deposition may be detrimental to flood control in sewer systems. The invention is specifically concerned with measuring an electrical property such as the conductivity or capacitance in different mediums and therefore quantifying the depths of the different mediums. The measurement of an electrical property such as conductance or capacitance of the medium may also indicate the nature of the medium such as sediment structure, water salinity, and the presence of pollutants. The device includes an array of elongate, substantially mutually parallel electrodes each having a predetermined length, the lengths being incremented stepwise from a shortest electrode to a longest electrode. The device includes electronic circuitry to apply a potential difference across selected pairs of electrodes and to measure a resulting electrical property between each selected pair of electrodes, the measured electrical property providing an indication of a submersion depth of the pair of electrodes in the at least one medium.
