17. A method of dewatering a slurry dredged from a source of water, wherein the slurry is dewatered to form a solid material and effluent water, said method comprising the steps of:
(a) providing a dewatering system that includes a plurality of support frames arranged to enclose an interior space of the dewatering system, geo-fabric material positioned on a portion of the support frames, and a dump door assembly associated with at least one of the support frames, wherein the dump door assembly comprises a plurality of hatches;
(b) adding a slurry to the interior space of the dewatering system; and
(c) separating the slurry into solid material and effluent water,
wherein during the separating of step (c), the solid material settles to a bottom of the interior space of the dewatering system, and the effluent water is discharged from the dewatering system by being filtered through the geo-fabric material and by passing through an open hatch of the dump door assembly.
