Abstract: A method for rehabilitating a land area comprises the step of using an excavating machine to extract dirt desired to be dispersed over the land area from another area, such as a ditch. The extracted dirt is mixed with water to form a slurry. The slurry is pumped to a high-pressure spray nozzle, and is then sprayed in a thin layer over the land area desired to be rehabilitated. The slurry can also be pumped to the land area at a controllable depth to achieve a desired land profile thereat.

Abstract: A method for constructing or rehabilitating a marsh or wetland comprises the step of inserting propagatable material into liquid or slurry emerging from a high-pressure spray nozzle to form a mixture. The liquid/ or slurry/propagatable material mixture is then sprayed over a marsh or wetland area desired to be constructed or rehabilitated.

Abstract: A method for distributing a dredged slurry of water and solids over a substantially large area wherein the solids may be distributed in a thin environmentally acceptable manner of uniform thickness or a land area or the bottom of a water area may be significantly raised in elevation. A plurality of aerial projectors in the form of nozzles mounted upon movable supports distribute the slurry and the supports and nozzles move over the area in a predetermined manner to produce slurry distribution as desired.

Abstract: A system for distributing a slurry of water and solids over a substantially large area wherein the solids may be distributed in a thin environmentally acceptable manner of uniform thickness or a land area or the bottom of a water area may be significantly raised in elevation. A plurality of aerial projectors in the form of nozzles mounted on vehicles distribute the slurry and the vehicle or vehicles move over the area in a predetermined manner and velocity to produce slurry distribution as desired.
