ABSTRACT:
An improved material movement system for use in a body of water for moving bottom materials. The system includes a vessel from which at least one propulsion unit is suspended and which has the ability to provide flow therefrom directed at a preselected angle toward the bottom. Deflector means are used with the propulsion units to control the direction of flow from the propulsion unit and to create pressure fluctuations in the flow from the propulsion which fluctuations are both low frequency and higher frequency. The pressure fluctuations, the deflection of the propulsion flow and other features are controlled by a central controlling computer. It is preferred that the high frequency fluctuations in the propulsion flow be controlled so that the frequency is adjusted to cause a maximum of excitation or movement of the bottom materials. This is done by propeller selection, speed of rotation and other factors under the control of the operator. The low pressure and low frequency fluctuations are controlled to arrive at the bottom in conjunction with the passing of a wave trough over the point on the bottom.
