Systems and methods for mitigation of beach erosion and escarpments
Embodiments for mitigating beach erosion and escarpments include a system comprising an offshore hydraulic dredging vessel; a conduit connected to the offshore hydraulic dredging vessel, wherein the conduit carries sand and seawater to the beach; a reservoir, wherein the reservoir is connected to the conduit; and a sand stabilization compound, wherein the sand stabilization compound is mixed with seawater in the reservoir to form a slurry; wherein the offshore hydraulic dredging vessel pumps the slurry, sand, and seawater to the beach.
1. A method for beach escarpment mitigation, the method comprising:
mixing a sand stabilization compound with seawater in a reservoir to form a slurry, wherein the sand stabilization compound is a hydrogel comprising one or more polysaccharides, one or more cross-linking agents, and one or more emulsifiers;
adding the slurry to a conduit carrying sand and seawater;
pumping the slurry, sand, and seawater to a beach; and
creating a new shoreline with the pumped slurry, sand, and seawater.
2. The method of claim 1 , wherein the one or more polysaccharides comprises one or more algae-derived phycocolloids.
3. The method of claim 1 , wherein the one or more polysaccharides comprises one or more plant-derived gums.
4. The method of claim 1 , wherein the pumping is performed by an offshore hydraulic dredging vessel, and wherein the sand is dredged from a seabed floor and pumped through the conduit by the offshore hydraulic dredging vessel.
5. The method of claim 4 , wherein the reservoir is located on the offshore hydraulic dredging vessel.
6. The method of claim 4 , wherein the reservoir is located on the beach.
7. The method of claim 4 , wherein the reservoir is located on a support vessel.
8. The method of claim 1 , wherein the beach comprises an escarpment, and wherein the pumped slurry, sand, and seawater collapses the escarpment.
9. The method of claim 8 , wherein the beach includes one or more sea turtle nesting sites.
10. A system for beach escarpment mitigation, the system comprising:
an offshore hydraulic dredging vessel;
a conduit, wherein the conduit is connected to the offshore hydraulic dredging vessel, and wherein the conduit carries sand and seawater to a beach;
a reservoir, wherein the reservoir is connected to the conduit; and
a sand stabilization compound, wherein the sand stabilization compound is mixed with seawater in the reservoir to form a slurry, and wherein the sand stabilization compound is a hydrogel comprising one or more polysaccharides, one or more cross-linking agents, and one or more emulsifiers;
wherein the offshore hydraulic dredging vessel pumps the slurry, sand, and seawater to the beach, wherein the pumped slurry, sand, and seawater creates a new shoreline.
11. The system of claim 10 , wherein the one or more polysaccharides comprises one or more algae-derived phycocolloids.
12. The system of claim 10 , wherein the one or more polysaccharides comprises one or more plant-derived gums.
13. The system of claim 10 , wherein the reservoir is located on the offshore hydraulic dredging vessel, and wherein the sand is dredged from a seabed floor and pumped through the conduit by the offshore hydraulic dredging vessel.
14. The system of claim 10 , wherein the reservoir is located on the beach.
15. The system of claim 10 , wherein the reservoir is located on a support vessel.
16. The system of claim 10 , wherein the beach comprises an escarpment, and wherein the pumped slurry, sand, and seawater collapses the escarpment.
17. The system of claim 16 , wherein the beach includes one or more sea turtle nesting sites.
18. The system of claim 10 , wherein the reservoir comprises a mixer and a drum.
