Abstract : This patent discloses a scour jet array system which includes a pump, both fresh water and surface water intakes, an automatic water mixing valve, a chemical buffer injector, a water heater, a series of scour jets with control valves, and a central control system. The control system senses the beginning of ebb tide for starting an initial scour jet, and as each jet scours the freshly deposited mud from the area, temperature, salinity and pH of the surface suction intake water are measured to determine the amount of fresh water injection, chemical buffer injection, water heating and duty cycle time in order to minimize the energy required to scour the sediments from the area.
