An apparatus for removing sediment from a bottom of a waterway and pumping the sediment through pipelines, comprising: a) a platform positionally fixed above a water surface of the waterway;b) a central vessel having an upper end portion, a lower end portion, and an interior, wherein the central vessel is connected to the platform at the upper end portion and anchored in the bottom of the waterway at the lower end portion;c) one or more water jets mounted on the lower end portion of the central vessel for liquefying or slurrying sediment;d) one or more vents at the lower end portion of the central vessel for filtering said slurried or liquefied sediment; ande) a pump positioned in the central vessel interior for removing said slurried or liquefied sediment from the central vessel interior via an outflow pipeline. 2. The apparatus of claim 1 further comprising a second pump and flow control valve located on the platform. 3. The apparatus of claim 2, wherein the flow control valve is used for directing water flow from the second pump to any of the following: 1) the outflow pipeline, 2) the pump for removing said slurried or liquefied sediment, 3) the one or more water jets, and/or 4) the central vessel interior. 4. The apparatus of claim 1, further comprising a grating on the one or more vents. 5. The apparatus of claim 1, further comprising a comb slidably attached on the interior of the central vessel, said comb having blades positioned in said one or more vents for movably clearing said one or more vents. 6. The apparatus of claim 1, wherein the one or more water jets are positioned at various locations on the one or more vents. 7. A method of removing sediment from a waterway bottom and pumping the sediment through pipelines, comprising: a) positionally fixing a central vessel in the bottom of the waterway, said central vessel having a top, a lower portion and an interior, and mounting a platform on said top of the central vessel and above a water surface;b) slurrying or liquefying sediment with one or more water jets on the lower portion of the central vessel;c) filtering said slurried or liquefied sediment into said central vessel via one or more vents at the lower portion of the central vessel;andd) pumping the sediment out of the central vessel and away from the water bottom via an outflow pipeline. 8. A system for sediment control and altering the average effective depth in a section of waterway comprising positionally fixing a plurality of the apparatuses as in claim 1 in series, wherein the apparatuses are placed in a river bed within a sand bar outside of a river navigational channel. 9. A system for sediment control and altering the average effective depth in a section of a waterway comprising positionally fixing a plurality of the apparatuses as in claim 1 in parallel, wherein the apparatuses are placed in a river bed within a sand bar outside of a river navigational channel. 10. The system of claim 8, wherein the system decreases the river's flow velocity. 11. An apparatus for removing sediment from a bottom of a waterway comprising: a) a platform positionally fixed above a water surface of the waterway;b) a central vessel connected to the platform and anchored in the bottom of the waterway, the central vessel having an upper end portion, a lower end portion, an exterior wall and an interior;c) a flow control valve and a water pump are housed on said platform;d) one or more vents positioned on the lower end portion of the central vessel used to filter the sediment into the central vessel interior;d) one or more water jets mounted in the central vessel interior and positioned above and below the vents, said water jets fluidly connected to the water pump and used to slurry or liquefy the sediment entering said vents;e) a sediment pump positioned in the central vessel interior and next to the vents, said sediment pump fluidly connected to an outflow pipeline. 12. The apparatus of claim 11, wherein the platform further comprises a shelter. 13. The apparatus of claim 11, wherein the platform further comprises an electric power supply. 14. The apparatus of claim 11, wherein the central vessel is a large diameter steel pipe. 15. The apparatus of claim 11, wherein the water jets emit water through the vents. 16. The apparatus of claim 11, wherein the lower end portion of the central vessel includes an anchoring piling. 17. The apparatus of claim 11, wherein the sediment pump is removable. 18. The apparatus of claim 11, wherein the water jets are removable. 19. The apparatus of claim 11, wherein the central vessel comprises interlocking steel panels. 20. The apparatus of claim 11, further comprises a plurality of sediment conveyors operably connected to the flow control valve. 21. The apparatus of claim 11, wherein the water jets are angled in the central vessel and are configured to create a counterclockwise rotation of sediment around the exterior of the central vessel.
