Accurate measurement and understanding of sediment volume, especially volume, is an important point. Conventional means for measuring the volume of the barge loading soil is to measure the height of several places on the pile of the loading soil by a skilled person on the barge, or to measure with a measuring tool, and use the measured value. Then, the volume is calculated by the integral calculation of the Simpson method.
