Abstract: A curtain enclosure formed from a flexible, non-permeable membrane is positioned adjacent to a section of riprap or similarly configured structure that has been installed along a shoreline. The curtain is stretched around rigid elongate posts and extends outward into the water from the edge of the riprap to create an enclosed containment area formed between the interior of the curtain and the edge of the riprap. The bottom of the curtain is weighted to sit along the bed of the water body and resist movement in that position. Once the curtain enclosure has been formed, larval bivalve organisms, such as oyster larvae, are poured into the curtain enclosure, and thereafter the curtain enclosure is maintained in that position for a period sufficient to promote attachment and growth of the larvae on the riprap.

Abstract: The present invention provides a low-energy coastal beach restoration method, comprising: constructing a convex beach berm, determining an aspect ratio of the beach berm edge, determining a beach face slope, performing sand replenishment, determining the dredging zone and dredging depth, and determining the steps of building a sediment groin. The present invention utilizes the feature of the convergence effect of the wave energy on the headland, artificially constructs a convex headland shaped beach berm, and determines the required beach face range and slope according to the convex beach berm edge. During beach restoration, dredging around the beach face, while reducing mud sources and increasing the nearshore water depth, it also builds a convex nearshore terrain, which effectively increases the wave energy at the restoration site and improves the coast muddy situation of low-energy coasts.

The tapered top revetment blocks can be installed on the water side of the levee, or on the land side of the levee, or both sides.

Abstract: A carpet of wave energy conversion (CWEC) device mechanically couples an absorber carpet to one or more energy converters, thereby allowing for wave energy extraction from passing waves. The absorber carpet may be flexible material of a composite material that has a low elastic modulus in a longitudinal direction (to allow for stretching), and a relatively higher elastic modulus in a transverse direction (to better couple energy from wave to converters). Such designs have minimal wave reflections and high efficiencies within a relatively short extent of deployment. The resultant converted useful energy is available as either: 1) mechanical power including direct desalinization or electrical production; or 2) hydraulic power for a number of applications (including hydraulically powered motors supplying power to powered devices including generators), or pumping of the wave medium under pressure to an alternate location for irrigation or energy storage.

Abstract: An apparatus for collecting fluids into a reservoir, wherein the reservoir is floating on a body of water and has an opening in the bottom of the reservoir through which the fluids, such as petro-based products, arrive flowing upward from a submersible structure, such as a riser from a fluid source.

Abstract: Flexible containment tubes form sections of a dike for fluid containment. For example, multiple vinyl-coated polyester tubes with a 19-inch diameter may be filled with water and stacked on top of each other to create a temporary diversion dike.

Abstract: A method of building up and maintaining beach sediment, building and changing beach profiles, and controlling beach erosion that uses a series of varying diameter plastic pipes joined to obtain various lengths, laid parallel and on top of each other and situated perpendicular or at various angles to the shoreline. The pipes act to slow bottom currents and promote sand accretion in and around the pipes thereby stabilizing shoreline profiles and controlling beach erosion. The pipes are held together by cables or in a “cradle” to help stabilize the pipes on the sea bottom. Certain pipes have pre-drilled holes of various diameters through their sidewalls to allow in-flow of sand-carrying water such that the pipes become filled with sand acting to stabilize the pipes. Pipe diameter sizes are selected as necessary to accomplish most efficient sediment accumulation around the pipe structures.

Abstract: A constrained buoy experiencing vortex-induced, in-line and transverse angular motions and designed to absorb and attenuate the energies of streams, rivers and localized ocean currents is described. Referred to as a Finned-Spar-Buoy (FSB), the buoy design can be considered an exoskeleton, in that vertical fins are externally mounted on a vertical cylindrical float. The fins increase the drag coefficient by enhancing the wake losses. The FSB operates as a single unit or as a component of an array, depending on the application. The FSB can adjust to high-water events caused by tides, storm surges or spring-melting runoffs because the FSB can move axially along a center-staff which is attached to an anchor pole at a pivot point. The buoy-staff system is allowed to rotate in any angular direction from the vertical, still-water orientation of the center-staff. The FSB has a relatively small diameter-to-draft ratio, analytically qualifying the buoy as a slender-body.
